Description

Technical Field

[0001] This invention relates to a tax law document search engine, and more particularly to a cloud-based document processing method based on a tax law document search engine. Background Technology

[0002] Tax law documents are numerous and complex in version, making it a long-standing challenge for tax law professionals to quickly and accurately locate the target document. Against this backdrop, tax law document search engines have emerged; however, existing products have flaws in their interface presentation and workbook editing functions, failing to efficiently meet users' needs in applying tax laws.

[0003] More importantly, when users apply tax laws in their work and studies, there is no intelligent working system to support them. Existing products on the market are merely tools that can only provide tax law retrieval. The search results are only displayed on the product interface. If users want to apply multiple tax law documents retrieved in their work and studies, they need to download the search results to other storage media. The storage of search results is separated from the product system. The existing product design has created a disconnect between tax law retrieval and tax law application, causing long-term and profound confusion for users.

[0004] Specifically, the shortcomings and deficiencies of existing technologies are as follows:

[0005] 1. Due to limitations in screen display technology, users of existing products need to compare new and old regulations or apply related regulations in combination. They cannot intuitively view new and old regulations or related regulations on a single computer screen at the same time. They need to repeatedly minimize the window and switch between them, resulting in a very poor user experience.

[0006] 2. If users want to apply multiple tax law documents retrieved for specific work or study, they need to download the search results to other storage media. The retrieved files are only stored separately on other media, and the files are scattered without intelligent links. The files cannot be linked together. If users need to select some files from the retrieved files according to their work needs, they need to manually read all the files and make judgments or set search conditions again to start the search. Similarly, due to limitations in screen display technology, reading the downloaded files still cannot intuitively view the new and old regulations or related regulations on one computer screen at the same time. It is necessary to repeatedly minimize the window and keep switching, which is inefficient and has a poor user experience.

[0007] 3. When users are writing tax-related documents, if they need to copy and quote content from tax law documents, they need to close the document editing window and reopen the tax law document window; if they need to search for documents again, they need to close the document editing window and reopen the document search window; users need to switch windows multiple times during the document writing process.

[0008] When users submit written tax-related documents and add attachments to cite relevant tax laws, they need to manually enter the attachment file names, download the relevant files and manually create hyperlinks, and finally manually create a compressed file containing the document and attachments.

[0009] When a user writes multiple tax-related documents with the same or similar content, if the time interval between writing is long, the user will find it difficult to recall them accurately, resulting in repetitive work.

[0010] Writing tax-related documents is inefficient, time-consuming, and labor-intensive.

[0011] 4. Changes in the validity of documents cannot be detected in a timely and intelligent manner, leading to work errors.

[0012] For example, a company makes a decision based on a certain tax law document. The document was valid at the time of the decision, but the decision was delayed and the document became invalid before the decision was implemented. If the relevant personnel are not informed in time that the validity of the document has changed, it may lead to decision failure and work errors.

[0013] When new tax laws and tax incentives emerge, users may not be able to obtain them in a timely and accurate manner, leading to occupational risks and failure to enjoy the benefits of national policies.

[0014] In summary, existing products increase and waste users' time costs, resulting in a poor user experience. Summary of the Invention

[0015] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cloud file processing method based on a tax law document search engine, which can upload tax law documents of interest to the cloud and perform customized file management.

[0016] The objective of this invention is achieved through the following technical solution:

[0017] A cloud-based file processing method based on a tax law document search engine includes a step of uploading files to the cloud. Users upload the tax law documents they need after searching to the cloud. A client-side caching method is used, which uses JS and cookie technology to cache the data in the user's browser, enabling the uploading of searched files individually, selective batch uploading, or one-click uploading of all files.

[0018] The cloud file library lists all files uploaded by the user according to the upload time. Users can manage the uploaded files in detail according to their work needs and create different folders.

[0019] The method also includes a workbook editing step, providing the creation, viewing / editing, deletion, and WORD format download of tax-related documents, and displaying the first writing time and last update time of each document, as well as setting tag options, workbook selections, and text editing area and attachment display area for each document;

[0020] Using JS floating boxes and sliding drawer technology, an automatic binding is established between the "Quick Search" button and the search engine module. Clicking the "Quick Search" button will launch the search engine module. After searching for and clicking on the tax law document to be referenced, the content of the tax law document will be displayed in a split screen with the workbook editing page, allowing users to search for documents while writing written documents.

[0021] Using client-side caching technology, during the writing of tax-related documents, any documents that have been consulted are identified as necessary for writing the document, and these documents are displayed in the document's attachment area. Once the document is completed, the necessary documents can be selected as official attachments.

[0022] This system employs Office document compositing and template generation technologies, along with database association technology, to synthesize tax-related documents into a Word document and set it as the main document. Selected files are also synthesized into Word documents and set as attachments. The filenames of the selected files are set as the attachment directory names in the main document, arranged in the order of selection. The attachment directory names serve as fixed link points, consistent with the template. Office hyperlink technology and database association technology are used to establish the association between the main document and attachment documents in the template, as well as the link relationships between the attachment directory points in the main document. Automatic compression technology, Office hyperlink technology, and database association technology are used to automatically generate a downloadable compressed package from the main document and attachment documents, preserving the association between the main document and attachment documents, and the link relationships between the attachment directory points in the main document. Using Office hyperlink technology, when the user decompresses the downloaded compressed package, the association between the main document and attachment documents, and the link relationships between the attachment directory points in the main document, are still retained (clicking the attachment directory link points in the main document directly opens and views the relevant attachment documents). When the user activates the "Download as Word" button, the system automatically executes the aforementioned procedures.

[0023] Using database association technology, the system retrieves the workbook selections, document content, and attachment information of the user's edited document and establishes associations. When the user writes the same or similar document again, the system will promptly remind them.

[0024] The method further includes a file reminder step, comprising:

[0025] Users are notified of changes when the legal validity status of tax law documents used in cloud file repositories and workbooks changes.

[0026] Users are alerted when new tax laws are introduced.

[0027] Based on the industry information entered by the user, a reminder will be sent to the user when the tax incentive documents corresponding to their industry are updated;

[0028] Based on the industries, tax types, and project information that users are interested in, the system will send a reminder to users when there are updates to the tax incentive documents corresponding to the industries, tax types, and projects they are interested in.

[0029] The split-screen display step includes the following sub-steps:

[0030] S101: When the workbook editing page is opened, a split-screen area is created, and the workbook editing page is displayed in the split-screen area as the first split-screen display.

[0031] S102: When the first tax law document link is opened, the split-screen area is displayed in a split-screen format. The content of the first tax law document is used as the second split-screen and displayed side by side with the first split-screen within the split-screen area.

[0032] S103: When opening the link to the second tax law document, first determine whether the tax law document has been opened. If so, prompt that the document has been opened in the first split screen. If not, further split the screen area and display the content of the second tax law document as the third split screen, which is displayed side by side with the first and second split screens in the split screen area.

[0033] S103: When opening the third tax law document link, first determine whether the tax law document has already been opened. If so, indicate which screen the document is currently open in. If not, display the content of the third tax law document as the fourth screen in the screen area. The second, third, and fourth screens form a sliding hidden window. A scroll bar for dragging the display is generated at the bottom of the sliding hidden window. At the same time, the second screen is slid-hidden, and the first, third, and fourth screens are displayed in the screen area.

[0034] S104: When opening the link to the fourth tax law document, first determine whether the tax law document has already been opened. If it has, indicate which split screen the document is currently open in. At the same time, continue to determine whether the split screen is hidden by sliding. If it is hidden, proceed to display the split screen within the split screen area. If it is not opened, display the content of the fourth tax law document as the fifth split screen within the split screen area. Simultaneously, the third split screen is hidden by sliding, and the first, fourth, and fifth split screens are displayed within the split screen area.

[0035] S105: And so on, until the number of files opened by the user exceeds the system's preset maximum number of split screens, at which point the system will prompt that the number of split screens has reached its limit.

[0036] The beneficial effects of this invention are:

[0037] 1) This invention supports split-screen display, making the process of comparing and reading tax law documents more convenient. When searching, consulting and applying tax laws, users can complete the work on a computer screen in a split-screen manner, avoiding the inefficient work state of repeatedly minimizing windows and constantly switching.

[0038] 2) This invention supports uploading files to a cloud-based file library, enabling seamless integration of tax law retrieval and tax law application. Users can upload the files they need after retrieval to the smart cloud-upload file library, avoiding the loss of intelligent links and file associations after being stored on other media as in traditional methods. After uploading to the smart cloud, through the combined use of the upload file library module and the search engine module, users can efficiently select some files from the uploaded files according to their work needs. At the same time, since the links between files still exist, users can directly click on the links to find the corresponding files. Combined with split-screen display, this achieves high efficiency in file retrieval and application.

[0039] 3) This invention supports online workbook editing, enabling efficient and intelligent support for users in the process of writing tax-related documents. Combined with split-screen display, users can easily realize new work modes and scenarios such as associated document reminders, efficient document editing, and one-click automatic generation of attachments and compressed files, significantly improving work efficiency and professional experience.

[0040] 4) This invention supports a secretary function, enabling users to promptly learn about changes in the validity of tax law documents during tax law work, and also to recover accidentally deleted useful information, thus playing the role of an intelligent secretary for users, preventing professional risks and improving professional capabilities.

[0041] It also provides access to the latest document push notifications and tax incentive push notifications, enabling timely and accurate access to document information, prevention of occupational risks, enhancement of professional skills, and timely enjoyment of national policy dividends.

[0042] 5) The main document and attachment documents in the template are automatically generated into a downloadable compressed package, and the association between the main document and attachment documents and the link relationship of the attachment directory link points in the main document are preserved. When the user decompresses the downloadable compressed package, the association between the main document and attachment documents and the link relationship of the attachment directory link points in the main document are still preserved. Clicking the attachment directory link point in the main document can directly open and view the relevant attachment documents, and the user experience of the workbook editing function is excellent. Detailed Implementation

[0043] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] This invention provides a tax law document search engine and a supporting intelligent working system. The user groups applicable to this working system include: enterprises and institutions, accounting professionals, tax service practitioners in intermediary agencies (including tax agent firms, accounting firms, and law firms), tax system cadres, and teachers and students of finance and taxation colleges, etc.

[0045] A cloud-based file processing method based on a tax law document search engine includes a step of uploading files to the cloud. Users upload the tax law documents they need after searching to the cloud. A client-side caching method is used, which uses JS and cookie technology to cache the data in the user's browser, enabling the uploading of searched files individually, selective batch uploading, or one-click uploading of all files.

[0046] The cloud file library lists all files uploaded by the user according to the upload time. Users can manage the uploaded files in detail according to their work needs and create different folders.

[0047] The method also includes a workbook editing step, providing the creation, viewing / editing, deletion, and WORD format download of tax-related documents, and displaying the first writing time and last update time of each document, as well as setting tag options, workbook selections, and text editing area and attachment display area for each document;

[0048] Using JS floating boxes and sliding drawer technology, an automatic binding is established between the "Quick Search" button and the search engine module. Clicking the "Quick Search" button will launch the search engine module. After searching for and clicking on the tax law document to be referenced, the content of the tax law document will be displayed in a split screen with the workbook editing page, allowing users to search for documents while writing written documents.

[0049] Using client-side caching technology, during the writing of tax-related documents, any documents that have been consulted are identified as necessary for writing the document, and these documents are displayed in the document's attachment area. Once the document is completed, the necessary documents can be selected as official attachments.

[0050] This system employs Office document compositing and template generation technologies, along with database association technology, to synthesize tax-related documents into a Word document and set it as the main document. Selected files are also synthesized into Word documents and set as attachments. The filenames of the selected files are set as the attachment directory names in the main document, arranged in the order of selection. The attachment directory names serve as fixed link points, consistent with the template. Office hyperlink technology and database association technology are used to establish the association between the main document and attachment documents in the template, as well as the link relationships between the attachment directory points in the main document. Automatic compression technology, Office hyperlink technology, and database association technology are used to automatically generate a downloadable compressed package from the main document and attachment documents, preserving the association between the main document and attachment documents, and the link relationships between the attachment directory points in the main document. Using Office hyperlink technology, when the user decompresses the downloaded compressed package, the association between the main document and attachment documents, and the link relationships between the attachment directory points in the main document, are still retained (clicking the attachment directory link points in the main document directly opens and views the relevant attachment documents). When the user activates the "Download as Word" button, the system automatically executes the aforementioned procedures.

[0051] The template automatically generates a downloadable compressed package containing the main document and attachments, preserving the association between the main document and attachments, as well as the links in the attachment directory within the main document. When the user unzips the downloaded package, the association between the main document and attachments, as well as the links in the attachment directory within the main document, are still retained. Clicking on the attachment directory links in the main document allows direct access to the relevant attachments, resulting in an excellent user experience for the workbook editing function.

[0052] Using database association technology, the system retrieves the workbook selections, document content, and attachment information of the user's edited document and establishes associations. When the user writes the same or similar document again, the system will promptly remind them.

[0053] The method further includes a file reminder step, comprising:

[0054] Users are notified of changes when the legal validity status of tax law documents used in cloud file repositories and workbooks changes.

[0055] Users are alerted when new tax laws are introduced.

[0056] Based on the industry information entered by the user, a reminder will be sent to the user when the tax incentive documents corresponding to their industry are updated;

[0057] Based on the industries, tax types, and project information that users are interested in, the system will send a reminder to users when there are updates to the tax incentive documents corresponding to the industries, tax types, and projects they are interested in.

[0058] The split-screen display step includes the following sub-steps:

[0059] S101: When the workbook editing page is opened, a split-screen area is created, and the workbook editing page is displayed in the split-screen area as the first split-screen display.

[0060] S102: When the first tax law document link is opened, the split-screen area is displayed in a split-screen format. The content of the first tax law document is used as the second split-screen and displayed side by side with the first split-screen within the split-screen area.

[0061] S103: When opening the link to the second tax law document, first determine whether the tax law document has been opened. If so, prompt that the document has been opened in the first split screen. If not, further split the screen area and display the content of the second tax law document as the third split screen, which is displayed side by side with the first and second split screens in the split screen area.

[0062] S103: When opening the third tax law document link, first determine whether the tax law document has already been opened. If so, indicate which screen the document is currently open in. If not, display the content of the third tax law document as the fourth screen in the screen area. The second, third, and fourth screens form a sliding hidden window. A scroll bar for dragging the display is generated at the bottom of the sliding hidden window. At the same time, the second screen is slid-hidden, and the first, third, and fourth screens are displayed in the screen area.

[0063] S104: When opening the link to the fourth tax law document, first determine whether the tax law document has already been opened. If it has, indicate which split screen the document is currently open in. At the same time, continue to determine whether the split screen is hidden by sliding. If it is hidden, proceed to display the split screen within the split screen area. If it is not opened, display the content of the fourth tax law document as the fifth split screen within the split screen area. Simultaneously, the third split screen is hidden by sliding, and the first, fourth, and fifth split screens are displayed within the split screen area.

[0064] S105: And so on, until the number of files opened by the user exceeds the system's preset maximum number of split screens, at which point the system will prompt that the number of split screens has reached its limit.

[0065] The split-screen display module enables the display of a single computer screen in multiple locations, and this split-screen technology is integrated into all modules of the system. Utilizing Vue swiper page-turning technology, based on human reading habits and actual work needs, a maximum of three screens can be displayed within a single computer screen area. Content exceeding three screens can be displayed by dragging the scroll bar. Screen hide and close buttons are also provided, allowing for free switching between the first, second, and third screens.

[0066] This method involves uploading files to the cloud, which corresponds to the "Smart Cloud - Upload File Library" module, a secondary function module of the main interface under Smart Cloud. Users upload the tax law documents they need after searching to the cloud. A client-side caching method is used, leveraging JS and cookie technology to cache the data in the user's browser, enabling individual file uploads, selective batch uploads, or one-click uploads of all retrieved files.

[0067] This module includes: a cloud-based file library listing all user-uploaded files by upload time; users can manage uploaded files in detail and create different folders according to their work needs; matching uploaded files with legal levels and custom categories; and providing selection boxes for users to select files based on "document validity, time range, and keywords for further searching."

[0068] This module is implemented by: employing client-side caching (a key technology that uses JS and cookies to cache data in the user's browser) to enable individual file uploads, selective batch uploads, or one-click batch uploads of all files; using database storage to establish a detailed file upload management module; using database association to achieve automatic matching of legal levels and custom categories; and using dynamic caching (a common caching technique that automatically caches hot data of search results under different combinations of search conditions such as legal level, custom category, document validity, document date, and keywords, prioritizing hot data for secondary searches to speed up the search process) to achieve intelligent and efficient linkage between legal level, custom category, "selection fields for document validity, time range, and keywords to continue searching" and the search engine module. This linkage can be used multiple times to help users find the files they need in the uploaded file library in the shortest possible time.

[0069] This module's functions include: seamlessly integrating tax law retrieval with tax law applications. Users can upload the files they need after retrieval to the Smart Cloud File Library, avoiding the loss of intelligent links and file associations after being stored on other media as in traditional methods. After uploading to the Smart Cloud, the combined use of the File Library and Search Engine modules allows for efficient selection of files based on work needs. Furthermore, since the links between files remain intact, users can directly click on the links to find the corresponding files. Combined with split-screen display, this achieves high efficiency in file retrieval and application.

[0070] The steps for editing a workbook in this method correspond to the "Smart Cloud - My Workbook" module.

[0071] This module is located in the main interface - a secondary function module of the Smart Cloud.

[0072] This module includes: creating, viewing / editing, deleting, and downloading tax-related documents in WORD format, and displaying the first writing time and last update time for each document; setting titles, industry (tax type, custom) and other tag options, keywords and other workbook options for each document, as well as a text editing area and an attachment display area; and setting a "quick search" button for files.

[0073] The module is implemented by using JS floating boxes and side-sliding drawers to automatically bind the "Quick Search" button to the search engine module. Clicking the "Quick Search" button will launch the search engine module. After searching for and clicking on the tax law document to be referenced, the content of the tax law document will be displayed in a split screen with the workbook editing page, allowing users to search for documents while writing written documents.

[0074] Using client-side caching technology, during the writing of tax-related documents, any documents that have been consulted are identified as necessary for writing the document, and these documents are displayed in the document's attachment area. Once the document is completed, the necessary documents can be selected as official attachments.

[0075] This system employs Office document compositing and template generation technologies, along with database association technology, to synthesize tax-related documents into a Word document and set it as the main document. Selected files are also synthesized into Word documents and set as attachments. The filenames of the selected files are set as the attachment directory names in the main document, arranged in the order of selection. The attachment directory names serve as fixed link points, consistent with the template. Office hyperlink technology and database association technology are used to establish the association between the main document and attachment documents in the template, as well as the link relationships between the attachment directory points in the main document. Automatic compression technology, Office hyperlink technology, and database association technology are used to automatically generate a downloadable compressed package from the main document and attachment documents, preserving the association between the main document and attachment documents, and the link relationships between the attachment directory points in the main document. Using Office hyperlink technology, when the user decompresses the downloaded compressed package, the association between the main document and attachment documents, and the link relationships between the attachment directory points in the main document, are still retained (clicking the attachment directory link points in the main document directly opens and views the relevant attachment documents). When the user activates the "Download as Word" button, the system automatically executes the aforementioned procedures.

[0076] Using database association technology, the system retrieves the workbook selections, document content, and attachment information of the user's edited document and establishes associations. When the user writes the same or similar document again, the system will promptly remind them.

[0077] This module provides efficient and intelligent support for users in the process of writing tax-related documents. Combined with split-screen display, users can easily achieve new work modes and scenarios such as document reminders, efficient document editing, and one-click automatic generation of attachments and compressed files, significantly improving work efficiency and professional experience.

[0078] This method involves cloud file reminders, corresponding to the "My Secretary" module, which provides timely reminders of important work-related information.

[0079] This module includes two sub-modules: "File Reminders" and "Historical Query Records." "File Reminders" includes three sub-modules: "Latest Files," "Validity Changes," and "Special Offers." "Validity Changes" includes two sub-modules: "Uploaded File Library" and "My Workbooks." "Historical Query Records" displays the objects and timestamps of user queries.

[0080] The module is implemented as follows: It utilizes database association technology to automatically associate tax law documents used in the "Uploaded File Library" and "My Workbooks" with newly added "Repealed (Invalid)" documents in the work system. When the validity of tax law documents used in the "Uploaded File Library" and "My Workbooks" changes, the user is automatically notified, and a message is pushed to the "File Reminder" module. It also utilizes database association technology to automatically associate "Latest Files" with newly added "Policies and Regulations" documents in the work system. When a new "Policies and Regulations" document is added, the user is automatically notified, and a message is pushed to the "File Reminder" module. Furthermore, it utilizes database association technology to automatically associate "Preferential Offers" with newly added "Tax Incentives" documents in the work system, automatically notifying the user and pushing a message to the "File Reminder" module. Finally, it utilizes mobile internet push technology to achieve automatic association and reminders between the "File Reminder" module and the linked official account.

[0081] By using database log analysis and script programming to implement data recovery functionality, the deleted content in the "historical query records" can be recovered.

[0082] This module enables users to obtain timely and accurate information on changes in the validity of tax law documents, the latest documents, and tax incentives during their work using tax laws. It can also recover accidentally deleted useful information, acting as a smart assistant to help users prevent professional risks, enhance professional skills, and enjoy national policy benefits in a timely manner.

[0083] The above description is merely a preferred embodiment of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
