[0065] The present invention provides a system and method for online comparative auditing based on structured documents:

[0066] 1. The document storage module includes the following functions:

[0067] (1) Having the ability to store structured documents;

[0068] (2) It has the function of querying structured documents.

[0069] 2. The document editing module includes the following functions:

[0070] (1) It has the ability to edit structured documents online, allowing users to edit documents in a visual way. Different types of information in the document, such as title, table of contents, chapter title, article title, paragraph content, figure, table, etc., can be displayed and edited in different ways;

[0071] (2) It can parse and identify the structured data of the document and set a unique ID for each structured unit for identification;

[0072] (3) It is possible to transfer the content of each structural unit in the document to the document storage module for storage in a structured manner;

[0073] (4) The entire structured data of the document is stored in a tree structure.

[0074] 3. The document difference comparison module includes the following functions:

[0075] (1) For the same document, multiple versions can be stored after the user performs editing operations. The multiple versions of the document can be automatically saved by the system or actively triggered by the user;

[0076] a) For the same document, each structural unit block of the document has a unique ID. For example, the document title will have a unique ID when stored in the background.

[0077] b) When the content of a structural unit in a document changes, the ID in the structural unit does not change.

[0078] c) When a user deletes a structure in a document (such as a title), the attributes and ID of the structural unit will be deleted together, and the same applies to adding new ones.

[0079] d) When the user changes the content of the document, the module can automatically re-store a copy of the data in a small version according to the set time (such as 5 minutes), such as automatically generating document_1.

[0080] e) After the user changes the content of the document, the user can actively trigger the version generation behavior of the document according to his or her needs, such as actively generating document _A.

[0081] (2) It has the function of comparing different versions of the same document, finding the differences, summarizing the difference structures, and returning the difference results to the document display module for difference display;

[0082] a) It is possible to compare the structured data of two versions. First, the overall structure of the two versions is compared. The structural comparison results are divided into two categories:

[0083] i. Newly added data: If version A adds n structured units compared to version B, the IDs of the newly added structured units are returned;

[0084] ii. Deleting data: If version A has n fewer structural units than version B, the IDs of the reduced structural units are returned.

[0085] b) For the parts of the structural units with the same ID in the two versions, the text contents in the two units are compared using a text similarity comparison algorithm. If there are inconsistencies between the two parts of the text, the ID of the structural unit whose text content has changed is recorded, and the changed text content is also recorded.

[0086] c) It is capable of returning the IDs of newly added structural units, the IDs of deleted structural units, the IDs of structural units with changed text contents, and the text changes to the document display module.

[0087] 4. The document display module includes the following functions:

[0088] (1) Able to receive the comparison results and structured data of two versions of documents returned by the document difference comparison module;

[0089] (2) It is possible to visualize the document based on the two versions of the document in the returned results, and realize the function of displaying two documents simultaneously in the left and right areas of the same screen;

[0090] (3) It is capable of performing comparative rendering according to the comparative data in the returned results. For deleted structural units, the content is marked with a deleted color in the screen display area according to the returned ID data set. For newly added structural units, the content is marked with a newly added color in the screen display area according to the returned ID data set. For changed content, the changed text part in the structural unit is displayed according to the ID.

[0091] The example provides an implementation scenario for comparing two structured documents. The content of document A is as follows: Figure 7 As shown in the figure, the specific document comparison implementation process is as follows:

[0092] Step 1: Edit the user document and automatically save the document during the editing process_A document;

[0093] Step 2: The document editing module performs structured storage on the two versions of the document.

[0094] The structured data Data_A of document_A is as follows:

[0095]

[0096]

[0097] Step 2.1: The document structured editing module can parse and identify the document structured data, and set a unique ID for each structured unit for identification. For example, Document_A shown above, its structured data is subsequently referred to as Data_A. Each structured unit Block of the document has a unique blockId.

[0098] Step 2.2: The document structured editing module transfers the content of each structured unit to the document storage module to store the document in a structured manner;

[0099] Step 3: The user edits Document_B, so that entry 3 is added to Document_B. The content "This paragraph is used to illustrate the deletion function of the structured document" is deleted, and the content "This article is used to illustrate the modification function of the structured document" in Chapter 2 is modified to "This article is used to illustrate the document modification function". The modified Document_B is obtained.

[0100] Step 3.1: When the content of a structural unit in the document changes, the ID in the structural unit will not change, that is, the blockId in the Block whose structure has not changed in Data_A during the editing process will not change;

[0101] Step 3.2: When the user deletes the content "This paragraph is used to explain the deletion function of the structured document" in the document, the structured block with blockId "3a5c46f3-adb5-49b3-9757-aa9e61bcbbaa" in Data_A is deleted as a whole. The same is true for new additions. Since the user has added "3, new entry 3", Data_B has added a block with blockId "63f60531-1113-469d-b885-11399eaefe77" ​​based on Data_A.

[0102] Step 3.3: The user modified the content of "This article is used to illustrate the structured document modification function" to "This article is used to illustrate the document modification function", and the content of blockId "51d6d1b4-76e8-4f06-9e94-8491ceb74bf7" in Data_B was also modified, but the blockId did not change;

[0103] Step 3.4: The user keeps document_B, and the document difference comparison module generates and saves the corresponding structured data Data_B.

[0104] The structured data Data_B of document_B is as follows:

[0105]

[0106]

[0107]

[0108] Step 4: The document difference comparison module compares Data_A and Data_B;

[0109] Step 4.1: First, compare the overall structures of the two versions. The structural comparison results are divided into:

[0110] i. Newly added data: Data_B adds one structured unit compared to Data_A, so the newly added structured unit "63f60531-1113-469d-b885-11399eaefe77" ​​is returned;

[0111] ii. Delete data: If version Data_B has one less structural unit than version Data_A, the reduced structural unit "3a5c46f3-adb5-49b3-9757-aa9e61bcbbaa" is returned;

[0112] Step 4.2: For the part with the same blockId in Data_B compared to Data_A, use the text similarity comparison algorithm to compare the text content in the two units. It is found that the text content of "51d6d1b4-76e8-4f06-9e94-8491ceb74bf7" is different in Data_B and Data_A, and the comparison result is given.

[0113] Step 4.3: Return the above results to the document display module. The comparison process is as follows Fig. 9 As shown;

[0114] Step 5: The document display module receives the comparison results and structured data of the two versions of the document returned by the document difference comparison module. The data structure of the returned comparison results is as follows:

[0115]

[0116]

[0117] Step 5.1: The document can be visualized based on the two versions of the document in the returned results, so that the two documents can be displayed simultaneously in the left and right areas of the same screen;

[0118] Step 5.2: Compare the data in the returned results. For blockId in "delete", mark the content with the deleted color in the screen display area. For blockId in "add", mark the content with the added color in the screen display area. For blockId in "change", display the content according to the three standards of "delete", "add" and "change" in the result, as follows Fig.10 Shown

[0119] The above are only preferred embodiments of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
