[0035] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0036] The terms "first," "second," etc., used in this application's specification are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class, without limiting the number of objects. For example, a first object can be one or more, where "more" means at least two. Furthermore, in the specification, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] The terms "at least one" and "at least one of" in this application's specification refer to any one, any two, or a combination of two or more of the included objects. For example, "at least one of a, b, and c" can mean "a", "b", "c", "a and b", "a and c", "b and c", and "a, b, and c", where a, b, and c can be single or multiple, and multiple means at least two. Similarly, "at least two" means two or more, and its meaning is similar to "at least one". The identifiers in this application are text, symbols, images, etc., used to indicate information, and can use controls or other containers as carriers for displaying information, including but not limited to text identifiers, symbol identifiers, and image identifiers.

[0038] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The terminology involved in the embodiments of this application is explained below.

[0039] PDF document: A format for displaying and printing electronic documents across various operating systems and devices. Initially, PDF applications only included basic layout and graphics features, but over time and with technological advancements, PDF documents have been continuously improved and expanded. Now, PDF documents have become a widely used electronic document format globally, used for various purposes and everyday applications, including e-books, reports, forms, and contracts.

[0040] Controls: Elements in a graphical user interface that can receive user input to perform corresponding processing or display relevant data. Controls can include, but are not limited to, virtual buttons, sliders, progress bars, and checkboxes.

[0041] Interface: Refers to the medium through which users interact with electronic devices. The interface allows users to send commands to the system via input devices and receive feedback information via output devices. Input devices can be keyboards, mice, touchscreens, etc.; monitors, speakers, etc.

[0042] Intelligent document catalog: This refers to the document retrieval catalog provided in this application embodiment. It is generated by parsing the PDF document content using document artificial intelligence (AI) and is used to present the document's chapter and paragraph framework structure. If the PDF document itself has a table of contents, the document AI directly reads and uses the existing chapter and paragraph framework to generate the catalog; if the PDF document does not have a table of contents, the document AI automatically generates a catalog that conforms to the document's logical chapter and paragraph framework based on its understanding of the full text content, providing guidance for users to quickly understand and find document content.

[0043] Table of Contents Chapter Summary: After the user clicks the chapter summary control, the document's AI automatically interprets the content of each chapter in the PDF document and generates a brief text summary of the corresponding chapter. This summary is associated with the document's table of contents, allowing users to quickly understand the core content of each chapter through the chapter summary in the table of contents, improving the efficiency of finding the corresponding chapter content.

[0044] Keyword understanding: When the keyword function is triggered, the document AI automatically analyzes and understands the entire PDF document, identifying and selecting nouns and words with professional academic value or that reflect the core points of the document. This accurate identification and grasp of keywords lays the foundation for subsequent content retrieval and other operations.

[0045] Keyword Explanation: After completing keyword understanding and selecting relevant professional academic terms or vocabulary, the document's AI provides concise explanations for these terms. The aim is to help users quickly understand the basic meaning of these terms when searching for relevant content using keywords, thus assisting them in better comprehending the document content.

[0046] Menu Bar: The menu bar is actually a tree structure, providing entry points for most of the software's functions. It's a collection of buttons grouped according to program function, located horizontally below the title bar. The menu bar, situated below the title bar, consists of nine menu commands, including File and View.

[0047] The document reading method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0048] The document reading method provided in this application can be applied to document management scenarios, such as e-books and digital publications, internal enterprise documents and training materials, government and public service documents, and legal documents and contracts.

[0049] The document reading method provided in this application embodiment will be illustrated below with examples of specific scenarios.

[0050] Scenario 1: Taking the user's need to read specific content in a PDF document as an example, if the user needs to view the content about AI models in the PDF document, the user can click on the table of contents that contains the AI ​​model content in the document search directory to enter the table of contents title, so that the electronic device can jump to the document chapter corresponding to the table of contents title that contains the AI ​​model content.

[0051] Scenario 2: Taking a user's need to retrieve specific content in a PDF document as an example, if the user needs to retrieve the keyword "AI" in the PDF document, the user can click and enter the keyword search control in the document interface, so that the electronic device can display all the keywords in the PDF document and the page numbers corresponding to all the keywords; then, the user can click and enter the page number corresponding to the keyword "AI", so that the electronic device can jump to the corresponding page number of the currently displayed content in the document interface, so that the user can view the document content corresponding to the keyword "AI".

[0052] It should be noted that the above scenarios 1 and 2 are merely exemplary examples of some scenarios that may be applied to the embodiments of this application. In actual implementation, the embodiments of this application can also be applied to any possible scenarios such as more document processing, and the embodiments of this application are not limited here.

[0053] Based on the scenarios described above in the embodiments of this application, the document reading method provided in this application generates a document table of contents for a PDF document. Based on the user's input of any one of at least two document chapter identifiers, the user is directly redirected to the document chapter corresponding to the first document chapter identifier in the document interface. This allows the user to quickly find the content they need, eliminating the need for the user to browse through each page of the PDF document to find specific content, thus improving the efficiency of viewing information in PDF documents.

[0054] For example, in scenarios such as e-books (e.g., professional textbooks, industry monographs) and digital journals, this solution can overcome the limitations of traditional e-books that only support basic page turning: for scanned e-books with unstructured tables of contents (e.g., older professional textbooks), it automatically generates a "document table of contents," allowing users to jump to the corresponding knowledge point by clicking on a chapter, replacing the inefficient operation of "manually marking page numbers." It generates a "table of contents summary" for each chapter; for example, the summary of "Chapter 3 Marketing Strategies" in a textbook can extract core models, such as the 4P theory, and key cases, helping students quickly review the chapter framework, especially suitable for organizing knowledge points during exam preparation. Through "keyword understanding," it extracts professional concepts from the book, such as "marginal cost" in economics and "bona fide acquisition" in law, and marks the explanation location of the concept in the book; users can jump to the corresponding analytical paragraph by clicking on the keyword. Combined with the "keyword definition" function, it provides textbook-specific interpretations of professional concepts, such as explanations combined with case studies in the book, preventing students from interrupting their reading due to misunderstandings of terminology, eliminating the need for additional dictionary or note-taking, and achieving a coherent learning loop of "reading-understanding-memory."

[0055] Internal technical manuals and job training materials, such as new employee onboarding manuals and equipment operation guides, are often long documents. This solution addresses the problem of "difficulty for employees to find information and slow comprehension": For scanned, older technical manuals, such as those without a table of contents, a "document table of contents" is automatically generated, dividing chapters logically into sections like "equipment principles - operating procedures - troubleshooting." Maintenance personnel can quickly locate key modules such as "fault code interpretation" without having to flip through every page. A "chapter summary" is generated for each chapter of the training materials. For example, the summary for the "customer communication skills" chapter can extract three core communication principles and two typical scenarios. HR can use this summary to quickly break down the key points of the course for employees during training, improving the efficiency of pre-training preparation and review. "Keyword understanding" extracts core terms from the manuals, such as "equipment pressure threshold" and "customer classification standards," and links them to the corresponding implementation details. New employees can quickly grasp the key points of operation by clicking on keywords. "Keyword definitions" are provided for professional terms, such as the definition of "customer classification standards" in the context of actual business operations, avoiding work deviations caused by differences in terminology understanding among employees from different departments. This is especially suitable for document sharing scenarios in cross-departmental collaboration.

[0056] Government announcements, policy interpretation documents, and public service guides, such as social security application procedures and housing provident fund withdrawal instructions, need to be accessible to the general public. This solution can improve document readability and information retrieval efficiency. For scanned policy documents with unstructured directories, such as old versions of medical insurance policy interpretations, a "document directory" is automatically generated, dividing chapters according to public concerns such as "enrollment conditions - payment standards - reimbursement procedures." Users can click to jump to the corresponding content, replacing the tedious operation of "searching for key information page by page." A "directory chapter summary" is generated for each chapter. For example, the summary of the "rental withdrawal" chapter in the "housing provident fund withdrawal instructions" can extract core information such as "application materials - processing procedures - arrival time." The public can quickly understand the key steps without reading the entire text, reducing the chances of "going to the wrong place or bringing the wrong materials." Core concepts in the document are extracted through "keyword understanding," such as "flexible employment enrollment" and "out-of-town medical treatment registration," and marked in the corresponding policy clause paragraphs. The public can click on the keywords to view detailed regulations. "Keyword definitions" are provided for professional government terminology. For example, explaining the applicable groups for "flexible employment insurance" in plain language can prevent the public from giving up reading due to obscure terminology. This is especially helpful for middle-aged and elderly people or users without professional backgrounds to access government information and improve the inclusiveness of public services.

[0057] Legal judgments, contract templates, and legal provisions are characterized by numerous clauses and high levels of technicality. This solution assists legal professionals and general users in efficiently reviewing and understanding these documents. For contract templates without a table of contents, such as scanned labor contracts, a "document table of contents" is automatically generated, dividing the document into chapters according to core modules such as "salary clauses - job responsibilities - liability for breach of contract." Employees can quickly locate key clauses by clicking, avoiding the risk of "missing important content." A "table of contents summary" is generated for each chapter of legal judgments, such as "case facts - evidence acceptance - judgment result," allowing lawyers to quickly grasp the core of the case without reading the entire text, improving the efficiency of case retrieval and analysis. "Keyword understanding" extracts legal terms from the documents, such as "joint liability" and "statute of limitations," and links them to corresponding clause explanations. General users can click on keywords to view professional interpretations. "Keyword definitions" are provided for legal terms, such as the definition of "statute of limitations" in specific cases, helping users without a legal background understand the meaning of the clauses. This is particularly useful for ordinary people signing contracts or understanding their legal rights, lowering the professional threshold for obtaining legal information.

[0058] The document processing method provided in this application is executed by a document processing device, which can be an electronic device, or a functional module or entity within an electronic device. This application does not limit the specific implementation of this method. The following will use an electronic device as an example to illustrate the document processing method provided in this application.

[0059] This application provides a document processing method. Figure 1 A flowchart illustrating a document processing method provided in an embodiment of this application is shown. Figure 1 As shown, the document processing method provided in this application embodiment may include the following steps 201 and 202.

[0060] Step 201: When displaying a document display interface, the electronic device receives a first input for the first document chapter identifier of at least two document chapter identifiers.

[0061] In this embodiment of the application, the document display interface includes a first PDF document and a document directory corresponding to the first PDF document, and the document directory includes at least two document chapter identifiers.

[0062] In this embodiment of the application, the first document chapter identifier can be any one of at least two document chapter identifiers.

[0063] Optionally, in this embodiment, the document display interface can be a professional PDF editing interface or an interface for displaying PDF documents in any application. The specific interface can be determined based on actual usage needs, and this embodiment does not impose any limitations.

[0064] Optionally, in this embodiment of the application, the user can click on the first PDF document in the electronic device to input, so that the electronic device can display the document display interface corresponding to the first PDF document.

[0065] Optionally, in this embodiment of the application, the electronic device may display the first PDF document in the first display area of ​​the document display interface, and display the document directory corresponding to the first PDF document in the second display area of ​​the document display interface.

[0066] It should be noted that the first display area and the second display area mentioned above do not overlap.

[0067] For example, the electronic device can display the document table of contents corresponding to the first PDF document in the left half of the document display interface and display the first PDF document in the right half of the document display interface.

[0068] Optionally, in this embodiment, the first PDF document can be a PDF document containing arbitrary content. The specific details can be determined based on actual usage requirements, and this embodiment does not impose any limitations.

[0069] Optionally, in this embodiment, the aforementioned document directory can be generated by the user based on the document content of the first PDF document using the first model. The specific implementation process can be found in the following embodiments, and will not be repeated here to avoid repetition.

[0070] For example, the first model mentioned above can be an AI model, a neural network model, or a large language model, etc. The specific model can be determined according to actual usage requirements, and this application embodiment does not impose any limitations.

[0071] Optionally, in this embodiment, the document directory may include at least one first-level document chapter identifier, and each first-level document chapter identifier may include at least one second-level document chapter identifier, and each second-level document chapter identifier may include at least one third-level document chapter identifier. Specifically, it can be determined based on the document content of the first PDF document, and this embodiment does not impose any limitations.

[0072] Optionally, in this embodiment of the application, the document chapter identifier may include the target title text and the page number corresponding to the target title text.

[0073] It should be noted that the above-mentioned document chapter identifiers are clickable document chapter identifiers, meaning that electronic devices can jump to the corresponding document chapter based on the user's input of the document chapter identifier.

[0074] For example, such as Figure 2 As shown, taking a tablet computer as an example, the left half area 11 of the document display interface 10 on the tablet computer, i.e., the second display area, can display the document directory 12. This document directory includes a general directory title "Intelligent Directory" and three first-level document chapter labels, namely "AI Model Overview", "AI Model Establishment", and "AI Model Application". The first-level document chapter label "AI Model Overview" includes a second-level document chapter label "AI Model Definition" and page number 1. The first-level document chapter label "AI Model Establishment" includes a second-level document chapter label "AI Model Modeling" and page number 4. The first-level document chapter label "AI Model Application" includes a second-level document chapter label "AI Model Usage Scenarios" and page number 10. The right half area 13 of the document interface 10, i.e., the first display area, can display the starting document chapter of the first PDF document: "Artificial intelligence, also known as intelligent machinery or machine intelligence, refers to machines created by humans that can exhibit intelligence. Generally, artificial intelligence refers to the technology of presenting human intelligence through ordinary computer programs."

[0075] In this embodiment of the application, the first input user triggers the electronic device to display the document chapter corresponding to the first document chapter identifier in the document display interface.

[0076] Optionally, in this embodiment, the first input can be a user's click input, swipe input, preset trajectory input, or voice input on the first document chapter identifier. The specific input can be determined according to actual usage needs, and this embodiment does not impose any limitations.

[0077] Step 202: The electronic device responds to the first input and displays the document chapter content corresponding to the first document chapter identifier.

[0078] In this embodiment of the application, the electronic device can jump from the starting document chapter displayed in the second area of ​​the document display interface to the starting position of the document chapter corresponding to the first document chapter identifier.

[0079] For example, in conjunction with scenario 1 above, and in conjunction with Figure 2 ,like Figure 3A As shown, users can click on the section marker "Definition of AI Model" in the second-level document to input their information, such as... Figure 3B As shown, this allows the tablet to jump from the starting document chapter displayed in the right half of the document interface 10 (13) to the document chapter corresponding to the secondary document chapter identifier "Definition of AI Model": "The definition of artificial intelligence in general textbooks is 'the research and design of intelligent agents,' where an intelligent agent refers to a system that can observe its surrounding environment and take actions to achieve its goals. John McCarthy's 1955 definition is 'the science and engineering of creating intelligent machines.' Andreas Kaplan and Michael Heinlein define artificial intelligence as 'the ability of a system to correctly interpret external data, learn from that data, and use that knowledge to achieve specific goals and tasks through flexible adaptation.' Experts in the National Science and Technology Expert Database define artificial intelligence as: Artificial intelligence is a technological science system that uses formalized data computation as its core method to endow machines or programs with the ability to simulate human intelligent behavior, such as learning, reasoning, perception, and decision-making, in order to replace or assist manual labor in intelligently performing complex tasks in the physical and information worlds."

[0080] Optionally, in this embodiment of the application, the electronic device, in response to the first input described above, may mark the starting text of the document chapter corresponding to the first document chapter identifier.

[0081] In this embodiment of the application, the electronic device can mark the starting text of the document chapter corresponding to the first document chapter identifier using a first marking method.

[0082] Optionally, in this embodiment, the first marking method may include any of the following: color marking, highlighting, bolding, or underline marking. The specific method can be determined according to actual usage requirements, and this embodiment does not impose any limitations.

[0083] For example, combined Figure 3B ,like Figure 4As shown, the tablet computer can boldly display the starting text of the document chapter corresponding to the second-level directory title "Definition of AI Models" displayed in the right half area 13 of the document display interface 10: "The definition of artificial intelligence in general textbooks is 'the research and design of intelligent agents,' which refers to a system that can observe its surrounding environment and take actions to achieve its goals. John McCarthy's definition in 1955 was 'the science and engineering of creating intelligent machines.' Andreas Kaplan and Michael Heinlein defined artificial intelligence as 'the ability of a system to correctly interpret external data, learn from that data, and use that knowledge to achieve specific goals and tasks through flexible adaptation.' Experts from the National Science and Technology Expert Database define artificial intelligence as: 'Artificial intelligence is a technological science system that uses formalized data computation as its core method to endow machines or programs with the ability to simulate human intelligent behavior, such as learning, reasoning, perception, and decision-making, in order to replace or assist manual labor in intelligently performing complex tasks in the physical and information worlds.'"

[0084] In this way, electronic devices can display the document chapter corresponding to the first document chapter identifier while marking the starting text of the document chapter corresponding to the first document chapter identifier, so that users can quickly locate the document chapter corresponding to the first document chapter identifier by marking it, thus improving the readability of PDF documents.

[0085] In the document reading method provided in this application embodiment, when displaying a document display interface, a first input is received for a first document chapter identifier among at least two document chapter identifiers; the document display interface includes a first PDF document and a document directory corresponding to the first PDF document, the document directory including at least two document chapter identifiers; then, in response to a second input, the document chapter content corresponding to the first document chapter identifier is displayed. In this solution, a document directory is generated for the PDF document, and based on the user's input for any one of the at least two document chapter identifiers, the user can directly jump to the document chapter corresponding to the first document chapter identifier in the document interface, so that the user can quickly find the content they need without having to browse the PDF document page by page to find specific content, thus improving the efficiency of viewing information in PDF documents.

[0086] Optionally, in this embodiment of the application, before the "electronic device receives the first input to the first document chapter identifier among at least two document chapter identifiers" in step 201 above, the document processing method provided in this embodiment of the application further includes the following steps 301 and 302.

[0087] Step 301: When the document display interface is displayed, the electronic device receives the second input.

[0088] In this embodiment of the application, the document display interface includes a table of contents generation control and a first PDF document.

[0089] Optionally, in this embodiment, the table of contents generation control can be directly embedded in the document display interface, meaning the document interface itself includes the table of contents generation control and does not require user input to trigger its display. Alternatively, the table of contents generation control can be displayed in the document display interface based on user input. The specific implementation can be determined according to actual usage requirements, and this embodiment does not impose any limitations.

[0090] For example, the above-mentioned catalog generation control can be displayed in the menu bar of the document display interface.

[0091] For example, such as Figure 5 As shown, the upper half 15 of the document display interface 10 may include a menu bar 16, which may include a viewing control 17, a format conversion control 18, and a table of contents generation control 19.

[0092] In this embodiment of the application, the second input is used to trigger the electronic device to display the document directory in the document interface.

[0093] Optionally, in this embodiment, the second input can be user input via clicking, long-pressing, preset trajectory input, or voice input on the directory generation control. The specific input can be determined according to actual usage requirements, and this embodiment does not impose any limitations.

[0094] Optionally, in this embodiment, the second input can be a long-press input, a preset trajectory input, or voice input by the user in the document display interface. The specific input can be determined according to actual usage needs, and this embodiment does not impose any limitations.

[0095] Step 302: The electronic device responds to the second input and displays the document directory corresponding to the first PDF document.

[0096] For example, combined Figure 5 ,like Figure 6 As shown, users can click and input data into the table of contents generation control 19 in the document display interface 10, such as... Figure 2 As shown, this allows the tablet computer to display the document directory 12 in the left half 11 of the document display interface 10.

[0097] Optionally, in this embodiment of the application, if the first PDF document is detected to include a table of contents, the electronic device generates a document table of contents based on the table of contents.

[0098] Optionally, in this embodiment of the application, the electronic device can input the first PDF document into the first model described above, thereby detecting whether the first PDF document includes a table of contents through the first model.

[0099] It should be noted that the specific process of the electronic device detecting whether the first PDF document includes a table of contents and generating a document table of contents from an existing table of contents can be found in the description in the relevant technology. To avoid repetition, it will not be repeated here.

[0100] Optionally, in this embodiment of the application, if the first PDF document does not include a table of contents, the electronic device generates a document table of contents based on the document content of the first PDF document.

[0101] In this embodiment of the application, the electronic device can input a first PDF document into a first model, and perform summary extraction processing on the document chapters of the first PDF document through the first model to obtain the summary text corresponding to each document chapter, i.e., the table of contents title. Then, the summary text corresponding to each document chapter is associated with each document chapter to obtain the document chapter identifier, thereby generating a document table of contents based on the display position of the document chapter in the first PDF document.

[0102] Optionally, in this embodiment, the number of words in the document section identifier is preset by the electronic device or user-defined. The specific number can be determined according to actual usage needs, and this embodiment does not impose any limitations.

[0103] For example, the number of words corresponding to the first-level document chapter identifier can be 4-5, and the number of words corresponding to the second-level document chapter identifier can be 5-10.

[0104] In this way, electronic devices can detect whether the first PDF document contains a table of contents, and then generate corresponding document search directories based on different document content, thereby improving the flexibility of electronic devices in generating document search directories.

[0105] In this embodiment, the electronic device can display a document directory on the document display interface based on the user's input, so that the user can quickly find the document content they need based on the document directory, thereby improving the efficiency of the electronic device in viewing document content.

[0106] Optionally, in the embodiments of this application, step 302 above can be specifically implemented by step 302a below.

[0107] Step 302a: In response to the second input, the electronic device displays the document table of contents corresponding to the first PDF document, and at least one of the following: document chapter summary content corresponding to at least two document chapter identifiers, keywords corresponding to the first PDF document, and professional terms corresponding to the first PDF document and their definitions.

[0108] Optionally, in this embodiment of the application, the document display interface further includes a chapter summary control.

[0109] Optionally, in this embodiment of the application, the above-mentioned chapter summary control can be displayed in a preset position or blank area in the second display area; or, the above-mentioned chapter summary control can be displayed in the menu bar of the document interface.

[0110] It should be noted that the aforementioned blank area refers to the area in the second display area that does not include text and controls.

[0111] Optionally, in this embodiment of the application, the second input can be an input to the chapter summary control.

[0112] Optionally, in this embodiment of the application, the electronic device responds to the second input by performing summary extraction processing on the document chapter corresponding to each document chapter identifier to obtain the chapter summary text corresponding to each document chapter identifier, and displays the corresponding chapter summary text in the display area corresponding to each document chapter identifier.

[0113] For example, the electronic device can input the document chapter corresponding to each of the at least two document chapter identifiers into the first model mentioned above, so as to perform summary extraction processing on the document chapter corresponding to each document chapter identifier through the first model, thereby outputting the chapter summary text corresponding to each document chapter identifier.

[0114] For example, combined with Figure 2 ,like Figure 7A As shown, users can click on the chapter summary control 20 displayed in the second display area 11 to input information, such as... Figure 7B As shown, the tablet computer can display the corresponding chapter summary text "The definition of artificial intelligence in general textbooks is 'the research and design of intelligent agents'" in display area 21 corresponding to the second-level directory title "Definition of AI Model"; and display the corresponding chapter summary text "AI modeling refers to using artificial intelligence technology to construct mathematical or computer models" in display area 22 corresponding to the second-level directory title "AI Model Modeling"; and display the corresponding chapter summary text "AI model application refers to various scenarios and technical implementations of using artificial intelligence models to solve practical problems or provide services" in display area 23 corresponding to the second-level directory title "AI Model Application".

[0115] Optionally, in this embodiment of the application, each document chapter identifier can correspond to a chapter summary control. The user can click on the chapter summary control corresponding to any document chapter identifier to input text, so that the electronic device can display the chapter summary text in the display area corresponding to that document chapter identifier.

[0116] In this way, by allowing users to input information into the chapter summary control, electronic devices can display the chapter summary text corresponding to each document chapter identifier, enabling users to quickly read the core content of each document chapter and improving the readability of PDF documents.

[0117] Optionally, in this embodiment of the application, the document display interface also includes a technical term search control.

[0118] For example, the aforementioned technical term search control can be displayed in the menu bar of the document display interface.

[0119] Optionally, in this embodiment of the application, the second input can be the user's input to the professional term search control.

[0120] Optionally, in this embodiment of the application, the electronic device, in response to the second input, can display at least one technical term from the first PDF document on the document display interface, and display the definition of each technical term in the display area corresponding to each technical term.

[0121] Optionally, in this embodiment of the application, the electronic device can input the first PDF document into the first model to perform technical term extraction processing on the first PDF document through the first model, output at least one technical term and the technical term definition corresponding to each technical term, and then display at least one technical term and the technical term definition corresponding to each technical term in the document display interface.

[0122] Optionally, in this embodiment of the application, the electronic device can display at least one technical term in the first PDF document through a pop-up window on the document display interface, and display the definition of each technical term in the display area corresponding to each technical term; or, the electronic device can display at least one technical term in the first PDF document in the fourth display area of ​​the document display interface, and display the definition of each technical term in the display area corresponding to each technical term.

[0123] For example, such as Figure 8 As shown, the electronic device can display the following in the display area 31 below the technical term "intelligent agent": "Intelligent agent is an important concept in the field of artificial intelligence, referring to any independent entity that can think and interact with its environment."

[0124] In this way, electronic devices can automatically display all the technical terms in the first PDF document, along with their corresponding definitions, by allowing users to input the technical term search control. This makes it easier for users to quickly read the definitions of technical terms and improves the readability of the PDF document.

[0125] Optionally, in the embodiments of this application, the document processing method provided in the embodiments of this application further includes the following steps 401 and 402.

[0126] Step 401: The electronic device receives the fourth input.

[0127] In this embodiment of the application, the fourth input mentioned above corresponds to the first information.

[0128] Optionally, in this embodiment, the first information may include at least one of the following: abstract words, keywords, user-input questions, etc. The specific details can be determined according to actual usage needs, and this embodiment does not impose any limitations.

[0129] Step 402: The electronic device responds to the fourth input by highlighting the document content that matches the first information.

[0130] Optionally, in this embodiment of the application, the document display interface further includes a summary search control.

[0131] Optionally, in this embodiment of the application, the fourth input can be the fourth input of the user entering the first summary term in the summary search control.

[0132] In this embodiment of the application, the fourth input is used to trigger the electronic device to display the original text content that matches the first summary word in the first display area.

[0133] Optionally, in this embodiment, the fourth input can be text input or voice input by the user in the summary search control. The specific input can be determined according to actual usage needs, and this embodiment does not impose any limitations.

[0134] Optionally, in this embodiment of the application, the electronic device responds to the fourth input by marking the first abstract term in the first chapter abstract text corresponding to the first abstract term, and displays the first content in the first display area.

[0135] In this embodiment of the application, the first content mentioned above is the original text content in the document chapter corresponding to the first chapter summary text that matches the first summary term.

[0136] In this embodiment of the application, the first chapter summary text corresponding to the first summary term can be understood as: at least one chapter summary text contains the chapter summary text of the first summary term.

[0137] Optionally, in this embodiment of the application, the above-mentioned first chapter summary text may be one or more.

[0138] Optionally, in this embodiment of the application, the electronic device may mark the first abstract term using the first marking method described above.

[0139] In this embodiment of the application, the electronic device can directly jump to the original text content in the PDF document that matches the first abstract term.

[0140] For example, combined Figure 7B ,like Figure 9A As shown, users can enter the first summary term "AI" in the summary search control 24, such as... Figure 9B As shown, the tablet computer can mark the first abstract term "AI" in the second display area 11 by bolding it, and display "The definition of artificial intelligence in general textbooks is "the research and design of intelligent agents" in the first display area 13.

[0141] In this way, the electronic device can trigger the user to enter the first summary term in the summary search control as a fourth input, which will then mark the first summary term in the chapter summary and directly display the original text content in the document chapter that matches the first summary term. This eliminates the need for the user to search for relevant content in the document chapter, thus improving the readability of the PDF document.

[0142] Optionally, in an embodiment of this application, the electronic device receives input of a first chapter summary text in at least one chapter summary.

[0143] It can be understood that the above-mentioned first chapter summary text is any one of the first chapter summary texts from at least one chapter summary.

[0144] In this embodiment of the application, the above-mentioned input user triggers the electronic device to display the source information of the first chapter summary in the corresponding second chapter.

[0145] Optionally, in this embodiment, the input can be user-generated text such as click input, swipe input, preset trajectory input, or voice input. The specific input can be determined according to actual usage needs, and this embodiment does not impose any limitations.

[0146] Optionally, in this embodiment of the application, the electronic device responds to input by displaying the source information of the first chapter summary in the corresponding second chapter.

[0147] In this embodiment of the application, the aforementioned source information includes the source location and source page number of the first chapter summary in the second chapter.

[0148] Optionally, in this embodiment of the application, the electronic device can display the source information of the first chapter summary in the corresponding second chapter in the document display interface through a pop-up window; or, the electronic device can display the source information of the first chapter summary in the corresponding second chapter in the first display area of ​​the document display interface; or, the electronic device can display the source information of the first chapter summary in the corresponding second chapter in the blank display area of ​​the document interface.

[0149] Optionally, in this embodiment of the application, the electronic device may display a second chapter in the second display area of ​​the document display interface in response to input.

[0150] For example, combined Figure 9B ,like Figure 10A As shown, users can click to input the chapter summary text "The definition of artificial intelligence in general textbooks is 'the research and design of intelligent agents'", such as... Figure 10B As shown, the tablet computer can display the second chapter, "The definition of Artificial Intelligence in general textbooks is 'the research and design of intelligent agents,' referring to a system that can observe its surrounding environment and take actions to achieve its goals. John McCarthy's 1955 definition is 'the science and engineering of creating intelligent machines.' Andreas Kaplan and Michael Heinlein define artificial intelligence as 'the ability of a system to correctly interpret external data, learn from that data, and use that knowledge to achieve specific goals and tasks through flexible adaptation.' Experts from the National Science and Technology Expert Database define artificial intelligence as: 'Artificial intelligence is a technological science system that uses formalized data computation as its core method to endow machines or programs with the ability to simulate human intelligent behavior, such as learning, reasoning, perception, and decision-making, in order to replace or assist humans in intelligently performing complex tasks in the physical and information worlds.'" Furthermore, pop-up window 25 displays the source location of the first chapter's summary in the second chapter: the second paragraph of the second chapter, page number: page 10.

[0151] Optionally, in this embodiment of the application, the electronic device can display the number of times the first chapter summary appears in the second chapter in a pop-up window, and display the first original text of the first chapter summary in the second chapter for the first time in the pop-up window, as well as a count control in the pop-up window; then, the user can click the count control to input, so that the electronic device can update the first original text displayed in the pop-up window to the original text of the first chapter summary in the second chapter for the second time.

[0152] For example, combined Figure 10B ,like Figure 11A As shown, the user can click on the count control 27 in the pop-up window 26 to input the count, such as... Figure 11BAs shown, the tablet computer can update the first original text displayed in the pop-up window, "The definition of artificial intelligence in general textbooks is 'the research and design of intelligent agents.' An intelligent agent refers to a system that can observe its surrounding environment and take actions to achieve its goals," to the first chapter summary. The second original text in the second chapter states, "Experts from the National Science and Technology Expert Database define artificial intelligence as: Artificial intelligence is a technological science system that uses formalized data computation as its core method to endow machines or programs with the ability to simulate human intelligent behavior, such as learning, reasoning, perception, and decision-making, in order to replace or assist humans in intelligently performing complex tasks in the physical and information worlds."

[0153] Optionally, in the embodiments of this application, the document processing method provided in the embodiments of this application further includes the following steps 501 and 502.

[0154] Step 501: The electronic device receives the fifth input.

[0155] Optionally, in this embodiment of the application, the document display interface also includes a keyword search control.

[0156] For example, the keyword search control described above can be displayed in the menu bar of the document display interface.

[0157] Optionally, in this embodiment of the application, the fifth input can be the user's input to the keyword search control.

[0158] Optionally, in this embodiment, the fifth input can be user input via clicking, swiping, or voice input on the keyword search control. The specific input can be determined based on actual usage needs, and this embodiment does not impose any limitations.

[0159] Step 502: The electronic device responds to the fifth input by displaying at least one of the following: each keyword corresponding to the first PDF document, and the document location corresponding to each keyword.

[0160] In this embodiment of the application, in response to the fifth input, the electronic device can display at least one keyword in the first PDF document on the document display interface, and display the page number corresponding to each keyword in the display area corresponding to each keyword.

[0161] Optionally, in this embodiment of the application, the electronic device can input the first PDF document into the first model to perform keyword extraction processing on the first PDF document through the first model, output at least one keyword and the page number corresponding to each keyword, and then display at least one keyword and the page number corresponding to each keyword in the document display interface.

[0162] Optionally, in this embodiment of the application, the electronic device may display at least one keyword in the first PDF document through a pop-up window on the document display interface, and display the page number corresponding to each keyword in the display area corresponding to each keyword; or, the electronic device may display at least one keyword in the first PDF document in the third display area of ​​the document display interface, and display the page number corresponding to each keyword in the display area corresponding to each keyword.

[0163] For example, in conjunction with scenario 2 above, and in conjunction with Figure 2 ,like Figure 12A As shown, users can click and input keywords into the keyword search control 28, such as... Figure 12B As shown, this allows the tablet computer to display three keywords in the third display area 29: "Intelligent Subject", "Perception", "Decision", and "Decision-Making".

[0164] In this way, electronic devices can automatically display all keywords in the first PDF document, as well as the page numbers corresponding to all keywords, by allowing users to input keywords into the keyword search control. This enables users to quickly locate the keywords they need, improving the readability of the PDF document.

[0165] Optionally, in the embodiments of this application, the document processing method provided in the embodiments of this application further includes the following steps 601 and 602; or steps 603 and 604.

[0166] Step 601: The electronic device receives the sixth input of the first keyword among all keywords.

[0167] Optionally, in this embodiment, the sixth input can be a user's click input, swipe input, preset trajectory input, or voice input for the first keyword. The specific input can be determined according to actual usage needs, and this embodiment does not impose any limitations.

[0168] Step 602: The electronic device responds to the sixth input by highlighting the document content that matches the first keyword.

[0169] In this embodiment of the application, the electronic device can mark document content that matches the first keyword using the first marking method described above.

[0170] In this embodiment, the electronic device can trigger the marking of the first keyword in the PDF document by the user inputting the first keyword, so that the user can quickly locate the content they need and improve the readability of the PDF document.

[0171] Step 603: The electronic device receives the seventh input of the first keyword among all keywords.

[0172] In this embodiment of the application, the seventh input user triggers the electronic device to mark the first keyword in the PDF document and displays the search result statistics on the document interface.

[0173] In this embodiment of the application, the above-mentioned search result statistics include the number of times the first keyword appears in the PDF document and the page number of the text.

[0174] Step 604: The electronic device responds to the seventh input and displays the document summary content that matches the first keyword.

[0175] Optionally, in this embodiment of the application, the electronic device can display search result statistics in the document interface via a pop-up window; or, the electronic device can display search result statistics in a blank area of ​​the third display area.

[0176] For example, combined Figure 12B ,like Figure 13A As shown, users can click to enter the keyword "intelligent subject," such as... Figure 13B As shown, this allows the tablet computer to display the text number corresponding to the keyword "intelligent subject" in pop-up window 30: 5 times and the text page numbers: page 10, page 15, page 17, page 20 and page 21.

[0177] In this embodiment, the electronic device can trigger the user to input a first keyword, which will then mark the first keyword in the PDF document and display search result statistics on the document interface. This allows the user to quickly locate the content they need through the search result statistics, thereby improving the readability of the PDF document.

[0178] Optionally, in this embodiment of the application, the electronic device receives an eighth input for the text page number.

[0179] In this embodiment of the application, the eighth input is used to trigger the electronic device to jump to the document chapter corresponding to the text page number.

[0180] Optionally, in this embodiment, the eighth input can be user-generated text page numbers via click, swipe, preset trajectory, or voice input. The specific input can be determined based on actual usage needs, and this embodiment does not impose any limitations.

[0181] Step 1102: The electronic device responds to the eighth input and jumps to the document chapter corresponding to the text page number.

[0182] For example, combined Figure 13B ,like Figure 14 As shown, users can click to enter the page number: Page 10, for example. Figure 6As shown, to allow the tablet to jump to the document chapter corresponding to page 10, "The definition of artificial intelligence in general textbooks is 'research and design of intelligent agents,' and an intelligent agent refers to a system that can observe its surrounding environment and take actions to achieve its goals," the first chapter summary is updated. The second time, the original text in the second chapter states, "Experts from the National Science and Technology Expert Database define artificial intelligence as: Artificial intelligence is a technological science system that uses formalized data computation as its core method to endow machines or programs with the ability to simulate human intelligent behavior, such as learning, reasoning, perception, and decision-making, in order to replace or assist humans in intelligently performing complex tasks in the physical and information worlds."

[0183] In this embodiment, the electronic device can jump to the document chapter corresponding to the text page number by the user's input, thereby improving the readability of the PDF document.

[0184] Optionally, in this embodiment of the application, the document processing method provided in this embodiment of the application further includes the following step 701.

[0185] Step 701: With the PDF document assisted reading function enabled, the electronic device displays the document display interface.

[0186] Optionally, in this embodiment of the application, the electronic device can enable the PDF document assisted reading function by the user's input of the first PDF document.

[0187] In this embodiment, the electronic device can improve the readability of PDF documents through document-assisted reading functions, eliminating the need for users to manually search for the document content they need.

[0188] The document reading method provided in this application embodiment is described below by way of example. The document reading method provided in this application embodiment may include steps 1 to 4 as described below.

[0189] Step 1: The user opens the PDF document and the function is triggered.

[0190] For example, when a user selects a PDF document to be processed through the "Open Document" control in the function interface of a large-screen electronic device, the electronic device automatically prompts "Do you want to enable the intelligent reading assistance function?" The user clicks "Enable" to trigger the subsequent document processing process. At this time, the interface will display a progress bar that says "Parsing the document, generating the auxiliary reading tool soon".

[0191] Step 2: The electronic device generates a document directory.

[0192] For example, after the electronic device completes the document parsing, it first generates a "Document Table of Contents" module on the left side of the document interface. If the original PDF has a table of contents, the module will directly synchronize and optimize the display format; if the original PDF does not have a table of contents, the electronic device will automatically generate a chapter framework that conforms to the document logic, and each chapter name in the table of contents will be presented in a clickable form.

[0193] Then, when the user clicks on any chapter name in the document's table of contents, the document reading area on the right side of the document interface will automatically jump to the beginning of that chapter, and the chapter title will be highlighted to help the user quickly confirm the current reading position.

[0194] Step 3: Users can view and filter the table of contents and chapter summaries.

[0195] For example, when a user clicks the "Generate Summary" button in the document's table of contents, the electronic device will immediately analyze the content of that chapter and display a "Table of Contents Chapter Summary" below the chapter name. The summary length is controlled between 100 and 200 words and includes the chapter's core viewpoints, key data, or main conclusions.

[0196] Then, if users need to quickly filter target chapters, they can enter keywords in the summary search box of the document's table of contents. The system will automatically match "Table of Contents Chapter Summaries" containing those keywords and highlight the original text content of the corresponding chapters. When a chapter is long (e.g., spanning 5 pages), and a sentence in the summary corresponds to multiple sources within the chapter (e.g., position A, position B, position C, etc.), after the user clicks on the highlighted chapter name, the document interface will first pop up the detailed content of the "Table of Contents Chapter Summaries," displaying the different sources in the summary, such as which pages they come from, and informing the user which parts of the content are selected from each page, providing a selector for the user to switch between them. Simultaneously, the extracted content will also be displayed and highlighted on each page, eliminating the need for users to search for the corresponding summary content page by page from the chapter's starting page.

[0197] Step 4: The user performs keyword understanding and retrieval operations.

[0198] For example, when a user clicks the "Keyword Function" button at the top of the interface, the electronic device will perform "keyword understanding" analysis on the full text of the PDF and generate a "keyword list" on the right side of the document interface. This keyword list contains academic terms, technical terms, core concepts, etc., sorted by frequency of occurrence, and each keyword is followed by a page number range in which it appears.

[0199] Then, when the user clicks on any keyword in the "Keyword List", the electronic device will automatically highlight all occurrences of that keyword in the entire text in the document reading area, and a "Search Results Statistics" will pop up at the bottom of the interface. If the user needs to pinpoint a specific occurrence, they can click on the page number in the statistics, and the reading area in the document interface will jump directly to the corresponding page.

[0200] Thus, for PDF documents without a table of contents due to design oversights or scanning, this solution fills the gap of traditional PDFs lacking structural guidance by automatically generating a "document table of contents." Users can quickly grasp the document's chapter framework without having to flip through each page, and can accurately jump to the relevant chapter by clicking on it. Compared to the traditional method of "blindly browsing to find content," this reduces the time required to understand the document structure by more than 60%. It is especially suitable for long documents such as academic reports and technical manuals that are hundreds of pages long, significantly reducing the cost for users to understand the overall framework of the document.

[0201] Moreover, the "Chapter Summary" function in the solution can directly present the core viewpoints and key information of a chapter. Users can quickly determine whether a chapter meets their reading needs through the summary without having to jump to the original text of the chapter. For example, when searching for content related to "experimental methods", users only need to enter keywords in the summary search box to filter out chapters containing that information, avoiding the repeated operation of "jumping-reading-returning to the table of contents". This reduces the content filtering time by an average of 30%, allowing users to focus more on the core content and improve the relevance and efficiency of reading.

[0202] Furthermore, traditional PDFs only allow navigation through the table of contents and cannot be used to search for specific content (such as technical terms or data conclusions). In contrast, the "keyword understanding" function of this solution can automatically extract the core vocabulary of the document and mark the page range: users can quickly locate all occurrences of the term in the entire text by clicking on keywords such as "machine learning algorithm" without having to search page by page. This reduces the time for searching specific content from "minutes" to "seconds", which is especially suitable for scenarios that require precise reference to document details, such as writing reports or verifying data, and greatly improves the accuracy and efficiency of content retrieval.

[0203] Then, for professional academic terms and technical terms in the document, the solution provides concise definitions and interpretations of their specific meanings within the document through the "keyword definition" function, avoiding interruptions in reading due to unfamiliarity with the terminology (such as additional searches for term meanings): for example, when a user encounters "convolutional neural network", clicking "view definition" will simultaneously provide an understanding of the basic definition of the term and its specific application scenarios in this document, without needing to switch to other tools for searching, achieving a seamless "reading-understanding" operation, lowering the reading threshold of professional documents, and improving the depth and fluency of users' understanding of the document content.

[0204] Finally, the "Document Table of Contents," "Chapter Summary," "Keyword Understanding," and "Keyword Explanation" in the solution are not independent functions, but rather form a collaborative reading assistance system: users can grasp the framework through the "Document Table of Contents," filter core chapters with the "Chapter Summary," locate specific content through "Keyword Understanding," and clear up comprehension obstacles with "Keyword Explanation." From "overall framework understanding" to "detailed content retrieval" and then to "professional terminology understanding," a complete reading loop is formed, thoroughly solving the pain points of traditional PDFs being "unguided, difficult to search, and difficult to understand," and providing a more efficient and convenient PDF reading experience on large-screen terminal devices.

[0205] It should be noted that the above-described method embodiments, or the various possible implementations of the method embodiments, can be executed individually, or, provided there are no contradictions, they can be combined with each other.
