Description

Technical Field

[0001] The present application belongs to the field of artificial intelligence technology, and specifically relates to an e-book reading method, device and electronic device. Background Art

[0002] With the increasing abundance of information on the Internet, faced with a vast amount of e-books, such as books, audios and videos, users usually choose to browse e-book introductions and e-book catalogs in order to find e-books of interest, and judge whether they are interested in further viewing through the e-book introductions and e-book catalogs.

[0003] At present, due to the limited content that can be displayed in the e-book introduction and e-book catalog, it is difficult for users to quickly and clearly understand the actual content of the e-book through the e-book introduction and e-book catalog. The e-book introduction is usually a brief text description that can only provide the basic background, theme and style of the e-book, and cannot deeply display the details and complexity of the e-book. Moreover, the e-book introduction is often written by the author or editor, which may be subjective and cannot fully reflect the true appearance of the e-book. The e-book catalog usually lists the chapters or parts of the e-book and provides structured information, but it cannot show the specific content of each chapter. The e-book catalog can only provide chapter titles and cannot show the key plots, character relationships and theme development within the chapters.

[0004] Since the information provided by the e-book introduction and the e-book catalog is limited, users cannot accurately judge whether the e-book meets their needs through this information. It takes a certain amount of time to read an e-book, especially for a long e-book. Users may need to invest more time to complete the reading. If the user finds that the e-book does not meet their interests or needs during the reading process, the time invested before becomes a waste. When selecting multiple e-books, users need to read them one by one, which may cause a lot of time to be consumed in the screening process. As a result, users usually waste a lot of time looking for e-books that they are interested in. Therefore, it is currently difficult for users to quickly and clearly understand the content of e-books. Summary of the invention

[0038] The following will be combined with the drawings of the embodiments of the present application to clearly describe the technical solutions of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present application belong to the scope of protection of this application.

[0039] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0040] It should be noted that the electronic book reading method provided in the embodiments of the present application can be executed by electronic devices such as mobile phones, tablet computers, laptop computers, PDAs, and vehicle-mounted electronic devices. In some embodiments of the present application, the electronic book reading method is executed by an electronic device as an example to illustrate the electronic book reading method provided in the embodiments of the present application.

[0041] The e-book reading method provided in the embodiment of the present application can be applied to the scenario of e-book reading, wherein a specific application scenario is the novel reading scenario: when a user browses novels on an e-book platform, he finds a novel called "Cosmic Trek". The e-book introduction mentions that this is a science fiction novel that tells the story of human exploration in the universe. The e-book catalog lists chapter titles, such as "Chapter 1: Set Sail", "Chapter 2: Unknown Planet", etc. However, the user cannot understand the specific plot, character relationships, and theme development of the novel through the introduction and catalog.

[0042] Another specific application scenario is reading academic papers; when a user searches for papers on artificial intelligence in an academic database, he finds a paper titled "Application of Artificial Intelligence in Medical Diagnosis". The e-book introduction mentions that the paper explores the application of artificial intelligence technology in the medical field, especially the progress in diagnosis. The e-book catalog lists chapter titles such as "Introduction", "Literature Review", "Methodology", "Experimental Results", etc. However, users cannot understand the specific research methods, experimental design, and main conclusions of the paper through the introduction and catalog.

[0043] The e-book reading method provided by the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0044] Figure 1 A flowchart of an e-book reading method provided in an embodiment of the present application.

[0045] like Figure 1 As shown, the electronic book reading method may include steps 110 to 120, and the method is applied to an electronic book reading device, as shown below:

[0046] Step 110, receiving an input for selecting a region of the electronic book program interface;

[0047] Step 120: When the area selected by the area selection input includes electronic book information, a content context map of the electronic book indicated by the electronic book information is displayed.

[0048] The electronic book information includes the book information of any electronic book, including but not limited to: the book cover image of the electronic book, the title of the electronic book, the author's name, and the book introduction.

[0049] An eBook cover image is typically a digital version of the book cover, used for display in an eBook reader, app, or online store.

[0050] The title, the formal name of the e-book, is usually shown on the cover image.

[0051] Author Name, the name of the author or co-author of the e-book, is usually listed below the cover image or on the book information page.

[0052] A book synopsis is a short book description that is usually used to attract readers and introduce the theme, content and style of the book. A content map is a visualization tool used to display the key plots, main events and story structure of a novel. The content map presents the overall framework of the novel in a graphical way, helping readers quickly understand the plot development, character relationships and theme of the novel.

[0053] Scenario 1: A user opens the novel "Douluo Dalu" on an e-book reading platform and selects the e-book cover area on the e-book program interface. The user wants to quickly understand the content of the novel. The e-book program interface displays the content context map of "Douluo Dalu". The content context map shows the key plots of the novel. Users can quickly understand the overall structure and plot development of the novel through the content context map.

[0054] Scenario 2: The user opens the paper "Application of Artificial Intelligence in Medical Diagnosis" in the academic database and selects the paper abstract area on the e-book program interface. The user hopes to quickly understand the main content of the paper. After the user selects the paper abstract, the e-book program interface displays the content context map of "Application of Artificial Intelligence in Medical Diagnosis". The content context shows the main parts and key contents of the paper. The user can quickly understand the overall structure and research progress of the paper through the map.

[0055] In an embodiment of the present application, by receiving area selection input on the e-book program interface, the user can select a specific area in the e-book through simple operations. When the area selected by the area selection input includes e-book information, a content context map of the e-book indicated by the e-book information is displayed. The content context map makes the complex e-book content intuitive and easy to understand in a graphical display manner. The content context map can help users quickly understand the content structure and logical relationship of the e-book, and users can grasp key information without reading the e-book page by page, so that users can quickly and clearly understand the content of the e-book.

[0056] In a possible embodiment, step 120 includes:

[0057] In the case where the area selected by the area selection input includes electronic book information, identifying the information content of the electronic book information to obtain electronic book bibliographic information, wherein the electronic book bibliographic information includes at least one of the following: the author's name, the title of the electronic book;

[0058] According to the electronic book bibliographic information, the electronic book content information is obtained from the electronic book database; the electronic book content information includes at least one of the following: electronic book chapter directory, electronic book original text;

[0059] The electronic book content information is input into a pre-trained content analysis model, and a content context map is output.

[0060] For example, when a user is ready to browse a novel in an e-book application, first, the user circles the novel cover with his knuckles. When no complete bibliographic information is detected in the user's circled area, the selection box will be automatically enlarged proportionally. If there is still no bibliographic information, the user will be reminded to circle again with his knuckles or input manually.

[0061] Figure 2a As shown, electronic book information 211, electronic book information 212, electronic book information 213 and electronic book information 214 are displayed; Figure 2a Among them, the e-book information 211 is specifically the cover thumbnail of the e-book "The Legend of the Great Saint", the e-book information 211 is specifically the cover thumbnail of the e-book "The Sacred Ruins", the e-book information 213 is specifically the cover thumbnail of the e-book "The Legend of Zhen Huan", and the e-book information 214 is specifically the cover thumbnail of the e-book "Douluo Dalu".

[0062] Figure 2b As shown, no bibliographic information is detected in the detection area 220 circled by the user's finger joint;

[0063] Figure 2c As shown, the detection area 230 is proportionally enlarged and the recorded information is successfully detected. If the recorded information is detected by the initial finger joint circle selection, there is no need to expand the detection area.

[0064] At this time, the user can use the knuckles to circle other monitoring areas again, or follow the second prompt information. The second prompt information indicates the operation method: long press the AI ​​icon at the top of the interface, a manual input box pops up, and manually enter the catalog information in the input box.

[0065] Figure 2d As shown, the second prompt information 250 includes: "Please enter the book you want to search" and an input box;

[0066] In response to the first input, when the e-book information is the e-book cover, in the step of identifying the e-book cover, specifically, the OCR function of the AI large model can be used to extract text from the e-book cover. If the cover contains words such as "Written by", "Author:", and "Book Title:", it is determined to be a novel. Among them, the name before "Written by" and after the "Author:" is the author's name, and the name after "Book Title:" or before "Author" is the novel name.

[0067] Figure 2e As shown, the graph generation identifier 260 is displayed. When an input to the graph generation identifier is received, a relationship graph associated with the target e-book is generated according to the e-book information.

[0068] Scenario 1: The user opens the novel "Douluo Dalu" on the e-book reading platform. When the selected area includes e-book information in the selected area, the information content of the e-book information is identified to obtain e-book bibliographic information, which includes at least one of the following: author name, title of the e-book. The e-book program interface identifies the e-book information of "Douluo Dalu" and obtains e-book bibliographic information, including the author name "Tang Jia San Shao" and the title of the e-book "Douluo Dalu".

[0069] According to the e-book bibliographic information "Douluo Dalu", the e-book program obtains the content information of "Douluo Dalu" from the e-book database, including the e-book chapter directory and part of the e-book original text. The e-book chapter directory, such as "Chapter 1: Douluo Dalu", "Chapter 2: Shrek Academy", "Chapter 3: Soul Master Competition", etc.

[0070] The obtained chapter directory and part of the original text are input into the pre-trained content analysis model, and the model outputs the content context graph of "Douluo Dalu". The graph shows the main chapters and key plots of the novel, and users can quickly understand the overall structure and plot development of the novel through the graph.

[0071] Scenario 2: The user opens the paper "The Application of Artificial Intelligence in Medical Diagnosis" in the academic database and selects the "Abstract" area on the e-book program interface. The user hopes to quickly understand the main content of the paper through the abstract. After the user selects the "Abstract" area, the e-book program interface identifies the e-book information of "The Application of Artificial Intelligence in Medical Diagnosis" and obtains e-book bibliographic information, including the author name "Zhang San" and the title of the e-book "The Application of Artificial Intelligence in Medical Diagnosis".

[0072] According to the e-book bibliographic information "The Application of Artificial Intelligence in Medical Diagnosis", the e-book program obtains the content information of the paper from the e-book database, including the e-book chapter directory and part of the e-book original text. The e-book chapter directory, such as "Introduction", "Literature Review", "Methodology", "Experimental Results", "Conclusion", etc.

[0073] The obtained chapter catalog and part of the original text are input into the pre-trained content analysis model, and the model outputs the content context map of "Application of Artificial Intelligence in Medical Diagnosis". The map shows the main parts and key contents of the paper, and users can quickly understand the overall structure and research progress of the paper through the map.

[0074] Therefore, users can identify e-book information and obtain relevant content information by selecting a specific area on the e-book program interface, and then generate a content context map through a pre-trained content analysis model. This function helps users understand the actual content of the work more comprehensively and deeply, so as to make more informed choices.

[0075] The e-book content information is input into a pre-trained content analysis model, and a content context map is output, including:

[0076] Inputting the e-book content information and keyword request information into a pre-trained content analysis model, outputting at least two content-level keywords of the e-book through the content analysis model, wherein the keyword request information is used to request the content analysis model to identify keywords of the main content of the e-book;

[0077] Input the keywords and chapter request information of the at least two content levels into a content analysis model, and output, through the content analysis model, the e-book chapter names and e-book chapter serial numbers associated with the keywords of the at least two content levels and the keyword association relationship between the keywords of each level and the keywords of the adjacent level, wherein the keywords of the adjacent level include at least one of the keywords of the previous content level and the keywords of the next content level;

[0078] Using the electronic book chapter serial number as an index, the keywords of the at least two content levels and the electronic book chapter name are associated and stored;

[0079] Generate at least two graph nodes of the content context graph according to the keywords of the at least two content levels, and generate at least two node connection lines of the content context graph according to the keyword association relationship;

[0080] A content context map is generated based on the at least two map nodes and the at least two node connection lines.

[0081] Specifically, after obtaining the e-book content information, the system organizes the keyword request information as follows: Please summarize the following content according to the main story line, output a description of less than or equal to 5 keywords, and input the e-book content information into the content analysis model. The number of keywords can be a preset value, such as 5, which is used to limit the number of first-level classification nodes generated by the content analysis model.

[0082] At this time, the content analysis model will output a group of keywords less than or equal to 5 for the keyword request information. The system records the keywords as the first-level keywords for generating the plot relationship map later.

[0083] Then, enter the keyword chapter request information, which can be: Please input the novel chapter names and e-book chapter numbers corresponding to the above keywords. The content analysis model will then output a set of chapter names and e-book chapter numbers. The system records the e-book chapter numbers as the first-level nodes of the subsequent plot relationship graph and the index for jumping between the specified chapters.

[0084] Question to the content analysis model: Please summarize the important stories under the several first-level keywords generated above into descriptions with less than or equal to 5 keywords. The content analysis model will output a group of keywords with a number less than or equal to 5 for the question. The system records the keywords as the second-level keywords for generating the plot relationship map later.

[0085] Question to the content analysis model: Please output the novel chapter names and e-book chapter numbers corresponding to the above secondary keywords. The content analysis model will then output a set of chapter names and e-book chapter numbers. The system records the e-book chapter numbers as an index for the secondary keywords and designated chapters in the subsequent plot relationship map to jump between each other.

[0086] Similarly, the newly generated keywords can be further refined and expanded to generate the third-level nodes of the plot relationship map. The number of third-level keywords here is also a fixed value built into the system.

[0087] Finally, the keywords summarized by the content analysis model are summarized to generate a plot relationship map according to the three-level node structure, in which nodes at the same level are sorted according to the size of their corresponding starting e-book chapter numbers, and the nodes from top to bottom correspond to chapter numbers from small to large.

[0088] Scenario 1: The obtained chapter catalog, part of the original text, and keyword request information are input into the pre-trained content analysis model, and the model outputs at least two content-level keywords of "Douluo Dalu", such as "Soul Master", "Shrek Academy", "Soul Ring", etc.

[0089] The keywords "Soul Master", "Shrek Academy", "Soul Ring" and chapter request information are input into the content analysis model. The model outputs the chapter names and chapter numbers associated with these keywords, such as "Chapter 1: Douluo Continent", "Chapter 2: Shrek Academy", "Chapter 3: Soul Master Competition", etc., and outputs the association between keywords, such as "Soul Master" and "Shrek Academy", "Soul Ring" and "Soul Master", etc.

[0090] Using the chapter number as an index, the keywords "Soul Master", "Shrek Academy", "Soul Ring" and chapter names "Chapter 1: Douluo Continent", "Chapter 2: Shrek Academy", "Chapter 3: Soul Master Competition" and so on are stored in association.

[0091] The graph nodes are generated based on the keywords "Soul Master", "Shrek Academy", and "Soul Ring", and the node connection lines are generated based on the association between the keywords, such as "Soul Master" and "Shrek Academy", "Soul Ring" and "Soul Master", etc. Based on the generated graph nodes and node connection lines, the content context graph of "Douluo Dalu" is generated, and users can quickly understand the overall structure and plot development of the novel through the graph.

[0092] Scenario 2: The obtained table of contents, part of the original text, and keyword request information are input into a pre-trained content analysis model. The model outputs at least two content-level keywords of "Application of Artificial Intelligence in Medical Diagnosis", such as "artificial intelligence", "medical diagnosis", "machine learning", etc.

[0093] The keywords "artificial intelligence", "medical diagnosis", "machine learning" and chapter request information are input into the content analysis model. The model outputs the chapter names and chapter numbers associated with these keywords, such as "Introduction", "Literature Review", "Methodology", "Experimental Results", "Conclusion", etc., and outputs the association between the keywords, such as "artificial intelligence" and "medical diagnosis", "machine learning" and "artificial intelligence", etc.

[0094] Using the chapter number as the index, the keywords "artificial intelligence", "medical diagnosis", "machine learning" and the chapter names "introduction", "literature review", "methodology", "experimental results", "conclusion" and so on are stored in association.

[0095] Generate graph nodes based on the keywords "artificial intelligence", "medical diagnosis", and "machine learning", and generate node connection lines based on the association between keywords, such as "artificial intelligence" and "medical diagnosis", "machine learning" and "artificial intelligence", etc. Based on the generated graph nodes and node connection lines, generate the content context map of "Application of Artificial Intelligence in Medical Diagnosis", through which users can quickly understand the overall structure and research progress of the paper.

[0096] The first-level keywords include: time travel, childhood, Shrek Academy, training with father and Poseidon; the subordinate keywords of the first-level keyword "childhood" include: daily life and turning point; accordingly, the superordinate keyword of the second-level keyword "daily life" is "childhood".

[0097] Thus, by viewing the plot relationship map, users can clearly see the relationship between events and how they are connected to each other. The relationship between adjacent keywords helps users grasp the timeline and causal relationship, making it easier for users to recall and predict future plots. Users can explore the details they want to know more deeply, enhancing the sense of participation and fun in reading. The embodiments of the present application allow users to find guidance in complex plots, providing a flexible and intuitive way to enhance the reading experience.

[0098] In some embodiments of the present application, step 120 includes:

[0099] Display a selection mark and a content context map control; the selection mark is used to frame the area selected by the area selection input;

[0100] Receiving a first input to the content context map control;

[0127] "Machine Learning" and "Artificial Intelligence": Machine learning is one of the core technologies of artificial intelligence. It enables computer systems to have learning and prediction capabilities in a data-driven way.

[0128] The content context map graphically displays the keywords and their relationships in the e-book, helping users quickly understand the structure and logic of the content. The map nodes cover keywords at different content levels, and users can clearly see different levels of content such as chapters, paragraphs, and concepts, so as to have a more comprehensive understanding of the knowledge system in the book. Users can select the area of ​​interest by selecting the mark frame and quickly generate a content context map of the area, so that they can grasp the key information without reading page by page.

[0129] The content context map displays the relationship between keywords through node connection lines, helping users discover the logical connections hidden in the text. The selection mark and content context map controls provide an intuitive interaction method, which users can easily operate and get instant feedback.

[0130] In a possible embodiment, after step 120, the method further includes:

[0131] Receiving control input to the e-book content interface;

[0132] In response to the control input, the electronic book relationship map is displayed in a preset display mode, wherein the target display mode is a display mode of target keywords associated with the target chapter, which is different from the display mode of keywords associated with chapters other than the target chapter.

[0133] When reading a specific chapter of a novel, users can quickly enter the plot relationship map interface by double-clicking the background area or swiping down the page. By highlighting the main characters, events, and key plots of the current chapter, users can intuitively see the core elements and plot development of the story, thereby better understanding and reviewing the context of the story.

[0138] By displaying the e-book relationship map in a target display mode, users can quickly grasp the core elements of the story, clarify the relationship between characters and the development of the plot, so that subsequent reading is smoother and more coherent. In the plot relationship map, users can also click on any keyword to quickly jump to the relevant chapter, further enhancing interaction and convenience.

[0139] In a possible embodiment, after step 120, the following steps may also be included:

[0140] Receiving a selection input of a graph node in the content context graph; wherein the content context graph includes at least two graph nodes, and different graph nodes are associated with different chapter contents in the electronic book;

[0141] In response to the selection input, the chapter information of the chapter associated with the graph node selected by the selection input is displayed.

[0142] Graph node: A graphical element in the content context graph, representing a keyword or theme in the e-book.

[0143] Selection input: The user selects a graph node by clicking, touching, or other interactive methods.

[0144] Chapter information: detailed information such as the original text, title, summary, main content, etc. of the chapter associated with the selected graph node.

[0145] There is a logical connection between the graph node and the chapter in the e-book, indicating that the content represented by the node is related to the chapter.

[0146] When reading a novel, the user can further explore the plot relationship map and receive a second input of a target keyword in the plot relationship map. The plot relationship map is presented in the form of 1-N level keywords, where N is a positive integer, to facilitate users to quickly navigate and find information.

[0147] For example, Figure 4 As shown, the target keyword corresponding to the graph node 410 selected by the selection input is "enrollment"; in response to the second input, the e-book content of the target chapter associated with the target keyword "enrollment" is displayed;

[0148] In this way, users can directly obtain specific chapters related to the plot keywords they are interested in, avoiding invalid searches. By viewing the content of specific chapters, users can better understand the changes in the plot, making users more flexible and efficient in understanding complex plots, thereby enhancing the overall browsing experience.

[0149] Scenario 1: The user selects the "Soul Master" graph node in the content context graph, triggering the selection input. In response to the user's selection input, the e-book program interface displays the chapter information associated with the "Soul Master" graph node, such as the detailed content and summary of chapters such as "Chapter 1: Douluo Continent", "Chapter 2: Shrek Academy", and "Chapter 3: Soul Master Competition".

In response to the user's selection input, the e-book program interface displays the chapter information associated with the "artificial intelligence" map node, such as the detailed content and summary of the "Introduction", "Literature Review", "Methodology", "Experimental Results", "Conclusion" and other chapters.

[0151] Users can quickly locate the corresponding chapter in the e-book by selecting a graph node without having to manually turn pages to search. The content context graph provides an intuitive way to navigate the content of the e-book. Users can jump directly to the relevant chapters through graphical nodes; through the association between graph nodes and chapters, users can obtain chapter information most relevant to the selected topic. Through the association between graph nodes and chapters, users can gain an in-depth understanding of the logical connections between different chapters, promote deep learning and thinking, and facilitate users to actively select graph nodes of interest. Select different graph nodes to obtain personalized content.

[0152] Therefore, by selecting a map node in the content context map, the system can quickly respond and display the chapter information associated with the node, which can help users gain a deeper understanding of specific parts of the work and make more informed choices.

[0153] The above-mentioned step of displaying the chapter information of the chapter associated with the graph node selected by the selection input may specifically include the following steps:

[0154] The content context map and chapter information of the chapter associated with the map node selected by the selection input are displayed in split screen.

[0155] The system displays the content context map and the chapter information associated with the selected map node on the screen at the same time, usually in a split-screen manner so that the user can view the map and detailed information at the same time.

[0156] Split screen display: Divide the screen into two or more parts, each part showing different content.

[0157] Chapter information: detailed information such as title, summary, main content, etc. of the chapter associated with the selected graph node.

[0158] Scenario 1: The user selects the "Soul Master" map node in the content context map, triggering the selection input.

[0195] By displaying reading marks on the map nodes, users can clearly know the location of the chapter they are currently reading in the content context map, avoiding getting lost in a large amount of content; reading marks provide an intuitive way to feedback the user's reading status and help users better manage their reading progress; users can quickly locate the chapter they are currently reading through reading marks without having to manually turn pages to search.

[0196] Therefore, when a user reads a specific chapter, the system will display a reading mark on the corresponding graph node to indicate that the chapter content is in the reading state. This function helps users customize and understand the content context of the work more flexibly, so as to make more informed choices.

[0197] In a possible embodiment, after step 110, the method further includes:

[0198] Step 130: display the character relationship graph of the e-book indicated by the e-book information.

[0199] A character relationship map is a visualization tool used to show the relationships and interactions between characters in novels, scripts, or other narrative works. The character relationship map presents the connections between characters in a graphical way, helping readers or viewers quickly understand the complex relationships and dynamic changes between characters.

[0200] The user selects a specific area on the e-book program interface, triggering the area selection input. In response to the area selection input, the system displays a character relationship map of the e-book related to the selected area. The character relationship map shows the relationship and interaction between the main characters in the e-book.

[0201] Scenario 1: The user opens the novel "Douluo Dalu" on the e-book reading platform and selects the "Character" area on the e-book program interface, triggering the area selection input. In response to the user's area selection input, the e-book program interface displays the character relationship map of "Douluo Dalu".

[0204] Therefore, by selecting a specific area on the e-book program interface, the system can quickly respond and display the character relationship map of the e-book related to the selected area. This function helps users understand the character relationships and interactions in the work more comprehensively, so as to make more informed choices.

[0205] In a possible embodiment, the electronic book content information and the character request information are input into a character analysis model, and at least two character names of the electronic book and the occurrence frequency of each character name are output;

[0206] Inputting the at least two character names and the occurrence frequency of each character name into a character analysis model, and outputting character introduction information and chapter number of each character name through the content analysis model;

[0207] Inputting the character relationship request information, the character introduction information of the character name and the chapter number into the character analysis model, and outputting the character relationship information through the content analysis model;

[0208] Generating at least two graph nodes of the character relationship graph according to the at least two character names, and generating at least two node connection lines of the character relationship graph according to the character relationship information;

[0209] A character relationship graph is generated based on the at least two graph nodes and the at least two node connection lines.

[0210] After obtaining the e-book content information, the system organizes the character request information as follows: please summarize the frequency of all characters appearing in the text, and input the e-book content information into the content analysis model; at this time, the content analysis model will output all character names and corresponding frequency data. For example, M is 50.

[0211] For example, the character request information is: Please select the top 50 characters with the highest frequency of appearance, and output their brief introductions and the corresponding chapter numbers. Here, 50 is a value built into the system, and can also be set to other values. Its purpose is to limit the number of characters that appear in the subsequent character relationship map to focus on displaying the relationship between the main characters. The system defaults to the characters with the highest frequency of appearance in the book as the main characters.

[0212] At this point, the content analysis model will output the 50 most frequent character names, the chapter number where they first appear, and a brief introduction.

[0213] Exemplarily, the character relationship request information is: Question to the content analysis model: Please output the relationship between the above selected characters.

[0214] At this time, the content analysis model will output the relationship between each character, and the output format is "Character A"-"Relationship"-"Character B".

[0215] The system obtains the relationship data between all characters generated by the content analysis model and generates it into a character relationship map. In the character relationship map, as long as there is a relationship between two characters, a connection line is established and the relationship is marked with text in the middle of the connection line.

[0216] The system will record the chapter number where each character appears as an index link for jumping between character relationship maps and novel chapters. When a user clicks on a character, he or she will jump to the corresponding novel page, and a brief introduction of the character summarized by the content analysis model will also be displayed above.

[0217] Scenario 1: The user opens the novel "Douluo Dalu" on the e-book reading platform and selects the "Cover" area on the e-book program interface, triggering the area selection input. The content information and character request information of "Douluo Dalu" are input into the character analysis model, and at least two character names, such as "Tang San" and "Xiao Wu", and the frequency of occurrence of each character name are output.

[0218] The character names "Tang San", "Xiao Wu" and the frequency of occurrence are input into the character analysis model. Through the content analysis model, the character introduction information of each character name is output, such as "Tang San is the protagonist and has twin martial spirits", "Xiao Wu is Tang San's partner and has the Soft Bone Rabbit martial spirit"; and chapter numbers, such as "Tang San" appears in chapters 1, 2, and 3, and "Xiao Wu" appears in chapters 2, 3, and 4.

[0219] The character relationship request information, character introduction information of the character name and the chapter number are input into the character analysis model, and the character relationship information is output through the content analysis model, such as "Tang San" and "Xiao Wu" are in a couple relationship, and "Tang San" and "Seven Devils of Shrek" are in a team relationship.

[0220] Graph nodes are generated according to the character names "Tang San" and "Xiao Wu", and node connection lines are generated according to the character relationship information, such as the couple relationship connection line between "Tang San" and "Xiao Wu", and the team relationship connection line between "Tang San" and the "Shrek Seven Devils".

[0221] Based on the generated graph nodes and node connection lines, a character relationship graph of "Douluo Dalu" is generated. Users can use the graph to quickly understand the character relationships and interactions in the novel.

[0222] Scenario 2: The user opens the paper "Application of Artificial Intelligence in Medical Diagnosis" in the academic database and selects the "Author" area on the e-book program interface, triggering the area selection input. The content information and character request information of "Application of Artificial Intelligence in Medical Diagnosis" are input into the character analysis model, and at least two character names and the frequency of occurrence of each character name are output.

[0223] The character names "Zhang San" and "Li Si" and their occurrence frequencies are input into the character analysis model, and the character introduction information and chapter number of each character name are output through the content analysis model. The character introduction information of each character name, such as "Zhang San is the first author, and his main research direction is artificial intelligence", "Li Si is the second author, and his main research direction is medical diagnosis"; chapter number, such as "Zhang San" appears in the introduction and methodology chapters, and "Li Si" appears in the experimental results and conclusion chapters.

[0224] The character relationship request information, character introduction information of the character name and the chapter number are input into the character analysis model, and the character relationship information is output through the content analysis model, such as "Zhang San" and "Li Si" are in a cooperative relationship, and "Zhang San" and "Wang Wu" are in a reference relationship.

[0225] Graph nodes are generated according to the character names "Zhang San" and "Li Si", and node connection lines are generated according to the character relationship information, such as the cooperation relationship connection line between "Zhang San" and "Li Si", and the reference relationship connection line between "Zhang San" and "Wang Wu".

[0226] Based on the generated graph nodes and node connection lines, a character relationship graph of "Application of Artificial Intelligence in Medical Diagnosis" is generated. Users can quickly understand the character relationships and interactions in the paper through the graph.

[0227] Therefore, by selecting a specific area on the e-book program interface, the system can quickly respond and generate a character relationship map of the e-book related to the selected area, which can help users more comprehensively understand the character relationships and interactions in the work.

[0228] In a possible embodiment, before step 130, the method further includes:

[0250] Scenario 2: The user clicks on the character name "Zhang San" in the character relationship map, triggering the fourth input. In response to the user's fourth input, the e-book program interface displays the character introduction information of "Zhang San" and the chapter information of at least one chapter associated with "Zhang San". The character introduction information of "Zhang San", such as "Zhang San is the first author, and his main research direction is artificial intelligence"; and the chapter information of at least one chapter associated with "Zhang San", such as "Introduction", "Methodology", etc.

[0251] By selecting a specific area on the e-book program interface, the system can quickly respond and display a character relationship map control in the display area associated with the e-book information. After the user clicks the control, the system will display the character relationship map of the e-book related to the selected area, including at least two character names and the character relationship information between at least two character names. The user can also further click on a character name in the character relationship map, and the system will display the character introduction information and related chapter information of the character. This function helps users to have a more comprehensive understanding of the character relationships and interactions in the work.

[0252] Thus, users can get the target character's background, personality traits and their importance in the story at a glance. By directly viewing the chapter content related to the character, users can have a deeper understanding of the character's role development and his role in the plot. Through the e-book content of the chapter associated with the target character's name, users can quickly find the relevant chapters, so that users can better connect the characters and the plot when viewing the e-book, which enhances the efficiency and interest of reading.

[0253] In a possible embodiment, after the step of receiving a fourth input of a character name in the character relationship graph, the method further includes:

[0254] Display the chapter information display control corresponding to each chapter associated with the character name;

[0255] After displaying the character introduction information of the character name selected by the fourth input and the chapter information of the chapter associated with the character name, the method further includes:

[0256] receiving a fifth input to a chapter information display control;

[0257] In response to the fifth input, the chapter information of the chapter corresponding to the chapter information display control selected by the fifth input is displayed.

[0258] Character Relationship Map: A map showing the relationships and interactions between the main characters in the e-book.

[0259] Chapter information display control: A control used to display specific chapter information. Users can view the chapter information by clicking the control.

[0260] The fourth input: a user clicks on a character name in the character relationship map.

[0261] Fifth input: user click operation on the chapter information display control.

[0262] In the process of reading the novel, the user can further explore the chapter content related to a specific character through the character information interface. When the user performs the eighth input to the chapter information display control in the character information interface, the system will respond and display the detailed content of the corresponding chapter.

[0263] like Figure 8 As shown, the user clicks on the chapter information display control 810, and the display jumps to the chapter information of the chapter corresponding to the chapter information display control selected by the fifth input.

[0264] Scenario 1: In response to the user's fourth input, the e-book program interface displays the chapter information display control corresponding to each chapter associated with "Tang San", such as "Chapter 1: Douluo Continent", "Chapter 2: Shrek Academy", etc. The user clicks the chapter information display control of "Chapter 1: Douluo Continent", triggering the fifth input. In response to the user's fifth input, the e-book program interface displays the chapter information of "Chapter 1: Douluo Continent", including the detailed content and summary of the chapter.

[0265] Scenario 2: In response to the user's fourth input, the e-book program interface displays the chapter information display controls corresponding to each chapter associated with "Zhang San", such as "Introduction", "Methodology", etc. The user clicks the chapter information display control of "Introduction", triggering the fifth input. In response to the user's fifth input, the e-book program interface displays the chapter information of "Introduction", including the detailed content and summary of the chapter.

[0266] From this, the user can further click on a character name in the character relationship map, and the system will display the character introduction information and the associated chapter information display control. After the user clicks the chapter information display control, the system will display the corresponding chapter information, which can help the user to have a more comprehensive understanding of the character relationships and interactions in the work.

[0267] In a possible embodiment, the above-mentioned step of displaying the chapter information of the chapter corresponding to the chapter information display control selected by the fifth input includes:

[0268] In the first display area, a character relationship map is displayed, and in the second display area, chapter information of the chapter corresponding to the chapter information display control selected by the fifth input is displayed;

[0269] Receive region adjustment input;

[0270] In response to the area adjustment input, the area sizes of the first display area and the second display area are adjusted.

[0271] First display area: Displays the character relationship map. This map can help users understand the relationship and interaction between characters in the chapter.

[0272] Second display area: Displays detailed information of the chapter selected by the user through the "fifth input". This may include chapter content, key events, character dialogues, etc.

[0273] Region adjustment input can include dragging boundaries, clicking buttons, or other gesture operations.

[0274] When the user inputs the area adjustment, the system will dynamically adjust the area size of the first display area and the second display area to suit the user's preference. For example, if the user wants to see more of the character relationship map, they can expand the size of the first display area and reduce the size of the second display area.

[0275] For example, the user is reading a novel and selects a chapter. The system will display two areas on the screen: a first display area for displaying the relationship diagram of the main characters in the chapter and a second display area for displaying the text content of the chapter.

[0276] like Fig. 9 As shown, in the first display area, the character relationship map is displayed, and in the second display area, the chapter information of the chapter corresponding to the chapter information display control selected by the fifth input is displayed. The user may feel that the relationship map is too small to clearly see all the character relationships, so the user drags the dividing line between the two areas to expand the size of the first display area. The system will immediately respond to this operation and adjust the sizes of the two areas so that the user can view the character relationship map more clearly.

[0277] Therefore, users can adjust the size of the display area according to their needs in order to better view and understand chapter information and character relationship maps.

[0278] In a possible embodiment, after step 130, the method further includes:

[0279] Receiving editing input of the character relationship map;

[0280] In response to the editing input, performing editing processing on at least one graph node or node connection line of the character relationship graph;

[0281] The editing process includes at least one of the following: renaming process, adding process, and deleting process.

[0282] Generate and display a character relationship map based on the information in the e-book, which shows the relationships and interactions between the main characters in the e-book.

[0283] Edit input, including: click, drag, double-click and other operations, used to select and edit nodes or connections in the graph.

[0284] When the user makes an edit input, the character relationship map will be edited accordingly. These edits include the following:

[0285] Rename processing: Users can select a graph node (representing a person) and rename it. For example, the user may want to change "Zhang San" to "Li Si".

[0286] Add processing: Users can add new nodes or connections to the graph. For example, users may find that an important person is missing from the graph, so they can add a new node and establish connections between this person and other people.

[0287] Deletion: Users can choose to delete nodes or connections in the graph. For example, users may decide that a minor character is not important to understanding the storyline, so they can delete the character's node and its associated connection.

[0288] For example, a user is viewing a relationship graph of a novel and finds that an important character "Wang Wu" is missing from the graph. The user can edit it by following the steps below:

[0289] Additional processing: The user clicks on a blank area in the graph, and the system pops up a dialog box. The user enters "Wang Wu" and confirms. The system adds a new node "Wang Wu" to the graph.

[0290] Additional processing: The user selects the "Wang Wu" node and drags a connection line to the "Zhang San" node. The system adds a connection line in the graph, indicating that there is a certain relationship between "Wang Wu" and "Zhang San".

[0291] Rename processing: The user finds that "Zhang San" should actually be "Li Si", so they double-click the "Zhang San" node, and the system pops up a dialog box. The user enters "Li Si" and confirms. The system updates the node name to "Li Si".

[0292] Deletion processing: Users believe that a minor character “Zhao Liu” is not important for understanding the storyline, so they select the “Zhao Liu” node and click the delete button, and the system deletes the node and all its connections.

[0293] Thus, users can customize the character relationship map according to their own understanding and needs. Through renaming, adding and deleting, users can more accurately reflect the character relationships in the e-book and better understand the storyline.

[0294] In one possible embodiment, receiving a sixth input;

[0295] In response to the sixth input, displaying a reading mark on the graph node selected by the fourth input in the character relationship graph;

[0296] Among them, the reading identifier is used to indicate that the chapter content corresponding to the graph node selected by the fourth input is in a reading state.

[0297] The sixth input may be a user click, double click or other operation to select a node in the graph.

[0298] In response to the sixth input, the system will identify the graph node selected by the user and display a reading mark on the node. This mark is used to indicate that the user is currently reading or has read the chapter content corresponding to the node.

[0299] Reading indicators are used to clearly indicate that the user is currently reading or has read a chapter. This helps users track their reading progress and understand which chapters have been read and which have not been read.

[0300] For example, the user is viewing a relationship graph of a novel and selects the node "Zhang San". The system will display a reading indicator on the node "Zhang San", such as a small icon or color change, indicating that the user is currently reading or has read the chapter content related to "Zhang San".

[0301] The user clicks or double-clicks the "Zhang San" node in the graph. The system displays a reading indicator on the "Zhang San" node, such as a small book icon or the node color changes to blue. The reading indicator clearly indicates that the user is currently reading or has read the chapter content related to "Zhang San".

[0302] Therefore, after the user selects a node in the character relationship map, the system automatically displays a reading mark to indicate that the chapter content corresponding to the node is in the reading state. This helps users better manage their reading progress and clearly understand which chapters have been read.

[0303] In a possible embodiment, after step 120, the method further includes:

[0304] Receiving a seventh input of the content relationship graph;

[0317] When receiving the selection input of the search option, the system displays a search box, and the user can enter the search term in the search box. According to the entered search term, the system searches and displays the search results matching the search term from the content relationship map.

[0318] Upon receiving selection input for the night mode switch option, the system switches the display mode of the content relationship map to night mode, which generally reduces screen brightness and may change background color and text color to reduce eye fatigue.

[0319] When receiving a selection input for the font size adjustment option, the system allows the user to adjust the font size of the text in the content relationship map. The user can adjust the font size through a slider, button or other means to adapt to different reading needs.

[0320] Upon receiving a selection input for a download option, the system allows the user to download the content relationship graph, and the user may choose to download the graph for viewing without a network connection.

[0321] For example, the user is viewing the content relationship graph of a novel and wants to perform the following operations:

[0322] Search option: When the user clicks the search option, the system displays a search box. The user enters "Zhang San", and the system searches for and highlights nodes and connections related to "Zhang San" in the graph.

[0323] Night mode switching option: When the user clicks the night mode switching option, the system switches the display mode of the map to night mode, the screen brightness is reduced, the background becomes dark, and the text becomes light.

[0324] Font size adjustment option: When the user clicks the font size adjustment option, the system displays a font size adjustment slider. The user slides the slider to adjust the font size of the text in the map to a larger or smaller size.

[0325] Download option: When the user clicks the download option, the system starts downloading the content relationship graph. After the download is complete, the user can view the graph offline.

[0326] As a result, users can perform a variety of operations in the content relationship map, including searching, switching to night mode, adjusting font size, and downloading the map. These features enhance the user experience and enable users to more conveniently manage and view the content relationship map.

[0327] In a possible embodiment, after step 110, the method further includes:
