Description

File comparison method, device, equipment and storage medium based on RPA and AI

technical field

Embodiments of the present invention relate to the technical field of process automation, and in particular, relate to a method, device, device, and storage medium for comparing files based on RPA and AI.

Background technique

RPA (Robotic Process Automation, robotic process automation) is to simulate the operation of human beings on the computer through specific "robot software", and automatically execute process tasks according to the rules.

AI (Artificial Intelligence) is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence.

RPA has unique advantages: low-code, non-intrusive. Low-code means that RPA can be operated without a high IT level, and business personnel who do not understand programming can also develop processes; non-intrusive means that RPA can simulate human operations without opening interfaces with software systems. However, traditional RPA has certain limitations: it can only be based on fixed rules, and its application scenarios are limited. With the continuous development of AI technology, the deep integration of RPA and AI overcomes the limitations of traditional RPA. RPA+AI=Hand work+Head work is greatly changing the value of labor.

In daily work, it is often necessary to compare two versions of contracts, laws and other documents to determine what changes have occurred in the newly generated document compared to the original document.

Fig. 1 is a kind of file comparison method based on RPA and AI provided by the embodiment of the present invention, this method is mainly applied to the client, specifically includes:

S100. Receive the reference file and comparison file uploaded by the RPA robot.

Specifically, the embodiment of the present invention can configure the RPA program in the electronic device that can log in to the client (it can be integrated or embedded in the client, or it can be independent of the client), so that the electronic device can simulate the RPA program according to the rules set in the RPA program The user's mouse and keyboard operations automatically log in to the client, and trigger the client to generate a file comparison request including reference files and comparison files by accessing the client, and send the file comparison request to the server so that the server can compare the reference files and comparison files Compare differences. Among them, when logging in to the client, the client can pop up a login interface containing a verification code image. In this case, the RPA robot can perform OCR recognition on the verification code image, obtain the verification code content in the verification code image, and store the verification code content Enter it into the corresponding edit box to successfully log in to the client.

The reference file and comparison file can be stored in the client, or in other storage space of the electronic device, or can be a paper file. When stored in other storage spaces of the electronic device, the RPA robot can search for reference files and comparison files from the other storage spaces, and upload the reference files and comparison files to the client, for example, by clicking the upload button. The two files are uploaded to the client, and the two files can also be dragged to the designated area by dragging and dropping to realize the file upload, or other upload methods can be used. When the reference file and/or comparison file is a paper file, the RPA robot can use OCR technology to convert the paper file into an image file or a text file (that is, an editable file composed of the text content in the paper file) , and then use the above method to upload to the client.

After the client receives the reference file and comparison file uploaded by RPA, it can render the reference file and comparison file to show the uploaded file to the user. Specifically, when the reference file and/or comparison file is a word file, you can first convert the word file into a PDF file, and then use the rendering library that comes with the client to render, and when the PDF file is a multi-page file, perform Multi-page rendering; when the reference file and/or comparison file is an image file other than tiff format, the rendering library that comes with the client can be used for rendering; when the reference file and/or comparison file is an image file in tiff format , you can use the proprietary rendering library in tiff format for rendering. Wherein, when converting a word file into a PDF file, the client may send the conversion operation to the server, and then the server may feed back the PDF file to the client for rendering.

S110. Send the reference file and the comparison file to a server.

After receiving the reference file and comparison file uploaded by the RPA robot, the client can receive the file comparison command triggered by the RPA robot, and then directly generate a file comparison request including the reference file and the comparison file according to the file comparison command, and send it to the server Send the file comparison request so that the server can compare the differences between the reference file and the comparison file. However, after the server receives the reference file and the comparison file, it often needs to identify the text in the two files before performing a difference comparison. If there are many clients sending file comparison requests to the server, it will cause the server to perform The efficiency of file comparison is reduced. In order to reduce the burden on the server and thereby improve the efficiency of document comparison, in the embodiment of the present invention, the client can first use OCR to identify the reference document and the comparison document, and obtain at least one page of text of the reference document and at least one page of the comparison document. text, and then send the recognized text to the server for difference comparison.

In practical applications, if at least one page of text in the reference document is directly compared with at least one page of text in the comparison document, that is, the Nth page of the reference document is compared with the Nth page of the comparison document, and If you do not pay attention to the relationship between pages, it is easy to cause inaccurate comparison results. For example, the reference document includes two pages of text, and the comparison document adds a page of text between the first page of text and the second page of text in the reference document, thereby forming three pages of text. If the single-page comparison method is used to compare the two The comparison result is that the text on the second page of the reference file is different from the text on the second page of the comparison file, and the reference file does not have the text on the third page, so the comparison result is the text on the third page of the comparison file. It does not exist in the reference documents, that is to say, the single-page comparison method will lead to the overall comparison result that the two documents are not the same except for the same text on the first page.

In order to avoid the problem of inaccurate comparison results, in the embodiment of the present invention, after the client uses OCR to identify the reference file and the comparison file, and obtains at least one page of text in the reference file and at least one page of text in the comparison file, first Perform text splicing, and then send the spliced text to the server. Specifically, when the target file is a file containing multiple pages of text, the multiple pages of text of the target file are spliced into one page of text with continuous context to obtain the target text; when the target file is a file containing a single page of text , obtaining a single page of text from the target file as the target text, wherein the target file includes a reference file or a comparison file, when the target file is the reference file, the target text is a reference text, when When the target file is the comparison file, the target text is the comparison text; sending the reference text and the comparison text to the server.

Among them, the continuous context refers to maintaining the sequence of the original text. The specific method of splicing multiple pages of text in a reference file or a comparison file into one page of text with continuous context can be to splice multiple pages of text in sequence according to the page order of the reference file or comparison file, so as to obtain a page with continuous context text.

What needs to be added is that, in order to improve the communication security between the client and the server, the server can authenticate the user information of the client to verify whether the user has the file comparison authority. Specifically, when the client sends the reference file and the comparison file to the server, it can also carry the user information of the client, so that the server can first authenticate the client according to the user information, and then verify the reference file and the comparison file when the authentication is passed. Compare files for difference comparison. Wherein, the user information may be a client account, may be a mobile phone number bound to the client account, may also be a user level or other information, and the implementation of the present invention does not limit the specific content of the user information, which may be determined according to specific circumstances. Certainly. There are many ways to authenticate user information, including but not limited to the following two: (1) Match the user information with the list of authorized users, and if the matching is successful, determine that the user corresponding to the user information has authorization , that is, the authentication passes. If the matching fails, it is determined that the user corresponding to the user information has no authority, that is, the authentication fails; (2) judge whether the user level in the user information exceeds the preset level, and if it exceeds the preset level, then The authentication is passed. If the level does not exceed the preset level, the authentication fails.

S120. Receive a difference comparison result of the comparison file relative to the reference file sent by the server.

After receiving the reference file and the comparison file, the server can compare the difference between the reference file and the comparison file according to a preset comparison algorithm. Specifically, the reference text and the comparison text may be compared according to a preset comparison unit, and comparison sub-results for each preset comparison unit are obtained. In the process of comparing the reference text and the comparison text according to the preset comparison unit, if it is determined that the reference subtext being compared (the reference text of the preset comparison unit) and the comparison subtext (the default comparison If it is determined that the reference sub-text being compared does not exist in the comparison text, then the corresponding comparison sub-result is determined as the content Delete; if it is determined that the comparison sub-text being compared does not exist in the reference text, then determine the corresponding comparison sub-result as content addition. In practical applications, the differences between two texts should include not only the same content, content deletion and content addition, but also content modification. Therefore, in order to allow users to see the difference between the comparison text and the reference text more intuitively, for the non-adjacent first comparison sub-result and the second comparison sub-result, if the first comparison sub-result and the second comparison sub-result Both of the two comparison sub-results have the same content, and the comparison sub-results between the first comparison sub-result and the second comparison sub-result include content deletion and content addition, but do not include the same content, then the The comparison sub-results between the first comparison sub-result and the second comparison sub-result are merged into one comparison sub-result, and the combined comparison sub-result is content modification. Wherein, the size of the preset comparison unit can be determined according to the actual situation, and can be a phrase, a sentence, a paragraph, and the like.

What needs to be added is that when comparing two texts, in addition to simply judging whether the characters or words used in the text content itself are the same, NLP technology can also be used to perform semantic analysis on the reference subtext and the comparison subtext. When the reference subtext and the comparison subtext have the same meaning but use different characters or words, it can be determined that the corresponding comparison subtext has the same content. In addition, the embodiment of the present invention can also support self-defined filtering rules, ignoring meaningless differences, that is, when there is a difference that satisfies the preset filtering rules in the difference between the reference subtext and the comparison subtext, ignore the difference that satisfies the preset filtering rules. Set the difference in filtering rules. For example, it can be set that the presence or absence of the particle "of" in a sentence does not affect the comparison result. When the server sends the difference comparison result to the client, it can also send the ignored difference, so that the client can display the ignored difference to the user.

When the comparison sub-result is content addition, content deletion or content modification, a piece of difference information can be generated for the comparison sub-result, so that all difference information can be fed back to the client after obtaining all the difference information. Wherein, each piece of difference information includes the difference type, the difference text in the reference file, the difference text in the comparison file, the difference position information of the difference text in the reference file, and the difference text in the comparison file. For the difference position information of the difference text in the file, the difference position information includes the page identification of the page to which the difference text belongs and the coordinate information of the difference text on the page to which it belongs. A comparison sub-result corresponds to a piece of difference information, and the difference types include content addition, content deletion, and content modification. The pagination mark is used to indicate which page the current paging is located in the entire file. For the coordinate information, a coordinate system can be established for each page, with the first character position of each page as the origin, and the horizontal and vertical axes to the right and vertical respectively, so that the Each character generates corresponding coordinates.

In one embodiment, after the client sends the reference file and the comparison file to the server, the server can add the task of comparing the reference file and the comparison file to the task queue, and compare the task with the comparison task. The task state of the paired task is stored in the task database, and when the task state of the comparison task changes, the task state in the task database is updated in time. The client can receive the comparison task status query command triggered by the RPA robot, and send the comparison task status query command to the server, so that the server can query the comparison task corresponding to the comparison task status query command from the task database , and feed back the queried task status to the client. Wherein, when the comparison task is not being executed, the task status may be unprocessed, when the comparison task is being executed, the task status may be processing, and when the comparison task is completed, the task status may be completed.

In addition, the server can actively feed back the difference comparison result to the client, and can also passively feed back the difference comparison result to the client. Among them, the specific implementation method of passively feeding back the difference comparison results to the client can be as follows: the client receives the comparison result query command triggered by the RPA robot, and sends the comparison result query command to the server, and the server queries the command according to the comparison result Send the corresponding difference comparison results to the client.

Among them, the specific implementation of the RPA robot triggering the client to send a comparison result query command or a comparison task status query command includes, but is not limited to, the RPA robot clicks the comparison result query button or the comparison task status query button on the client. Trigger the client to generate and send corresponding instructions.

S130. According to the difference comparison result, highlight the difference text in the comparison file and/or the reference file.

Wherein, the highlighted difference text in the comparison file is the text of the difference between the comparison file and the reference file, and the highlighted difference text in the reference file is the text of the difference between the reference file and the reference file. The text that describes the differences in the comparison files. The way of highlighting includes but is not limited to a combination of one or more of the following: bold font, change font color, increase font background color, highlight font, increase font, change to italic, add underline, add strikethrough, etc. When multiple difference types are included in the difference comparison result, different difference types may be highlighted in the same or different ways.

The specific implementation of this step may be: converting the coordinate information into DIV element position information; when the DIV element position information enters the display area of the file to which it belongs, according to the difference type corresponding to the DIV element position information and the The page identification corresponding to the position information of the DIV element highlights the difference text at the position information of the DIV element in the page indicated by the page identification. Among them, DIV is a positioning technology in cascading style sheets, and the DIV element is an element used to provide structure and background for block-level content in an HTML document. Encapsulate a display area for the reference file and the comparison file respectively, and one display area is a component, for example, two display areas arranged from left to right can be encapsulated on the interface to display the reference file and the comparison file respectively, and when the reference file And/or when there are many texts in the comparison file and cannot be displayed in one go, the scrolling display function of the scroll bar can be added.

It should be noted that when the difference text is highlighted in the comparison file and/or the reference file according to the difference comparison result, if the difference type contained in the current difference information is content deletion, then it can be Only the deleted text is highlighted in the reference file, or the text before the content deletion and the text retained after the content deletion can be highlighted separately, that is, the difference text contained in the difference information in the reference file and in the comparison file The difference files are highlighted. If the difference type contained in the current difference information is content increase, you can only highlight the added content in the comparison file, or you can highlight the text before the content increase and the text after the content increase respectively, that is, the difference information includes Both the difference text in the reference file and the difference files in the comparison file are highlighted. If the difference type contained in the current difference information is content modification, the text before content modification and the text after content modification can be highlighted, that is, the difference text contained in the difference information in the reference file and the text in the comparison file Difference files are highlighted.

Exemplarily, FIG. 2 is part of the text content of the reference file and the comparison file, and the difference text can be directly highlighted in the reference file and the comparison file, and the user can browse by dragging the scroll bar of the reference file and the comparison file. Among them, the bold and underlined text refers to the modified text, the italic and enlarged text refers to the text added in the comparison file, and the strikethrough text refers to the deleted text in the comparison file.

In one embodiment, in the case of encapsulating independent display areas for the reference file and the comparison file, when the user needs to compare and view a certain difference, he needs to drag the scroll bars of the two files to View, the operation is more cumbersome. In order to improve the efficiency of users viewing differences, the embodiment of the present invention can focus on the same piece of difference information, according to the DIV element position information of the difference text in the reference file, the DIV element position information of the difference text in the comparison file, and the difference Type, generate ID (Identity Document, ID card identification number), and carry out described ID and the DIV element position information of difference text in described reference file, the DIV element position information of difference text in described comparison file respectively Binding, when receiving the first synchronous positioning instruction triggered based on the reference file or the comparison file, bind the ID corresponding to the first synchronous positioning instruction to the difference text at the position information of all DIV elements Highlighting is done synchronously.

Wherein, the specific implementation of generating the ID includes but is not limited to: according to the preset order, the DIV element position information of the difference text in the reference file, the DIV element position information of the difference text in the comparison file and the difference type Perform concatenation to obtain a string. Wherein, different difference types may be represented by different characters, for example, "content deletion", "content addition" and "content modification" may be represented by "1", "2" and "3" in sequence. The first synchronous positioning instruction is an instruction generated when the user clicks on the display area of the reference file or the comparison file. When the client receives the first synchronous positioning instruction, it will activate the corresponding ID. For the component corresponding to the reference file or the comparison file, it will judge whether the activated ID is the same as the ID contained in itself. If it contains the same ID, the difference text at the position information of the DIV element corresponding to the ID can be highlighted display, and when the position information of the DIV element is not in the display area, the position information of the DIV element will be scrolled to the display area for display. For example, for the same piece of difference information, when the difference text "electronic equipment" in the reference file is on page 2 of the reference file, and the difference text "computing terminal" in the comparison file is on page 3 of the comparison file, the user can Click on the text "electronic equipment" on page 2 of the reference document, and the client will automatically synchronize, so that the comparison document will automatically scroll to page 3, and the text "computing terminal" will be highlighted.

In one implementation, in order to provide users with more ways to view the differences and facilitate users to view them according to their personal habits, the embodiment of the present invention can also display the difference details in the preset display area according to the difference comparison results, so The preset display area is an area other than the reference file display area and the comparison file display area, and the difference details include the difference type in each difference information, the difference text in the reference file, and the difference text in the comparison file. The diff text in the file. In addition, the difference comparison results can also be summarized, and the summary results can be displayed in display areas other than the reference file display area, the comparison file display area, and the preset display area. The summary result includes the total number of difference information and the page identification where the difference information is located. For example, the summary result is "After comparison, it is found that there are differences on pages 1, 3, 5, and 8 of the reference document, and there are 20 differences in total between the two documents".

Exemplarily, as shown in FIG. 3 , when displaying the difference, the client not only highlights the difference text in the reference file and/or the comparison file, but also displays the comparison result on the right. The upper part of the comparison result is the overall comparison result (ie, the summary result), and the lower part is the detailed comparison result (ie, the difference details). Users can browse the difference details by dragging the scroll bar in the detailed comparison result display area.

Since the preset display area is independent from the reference file display area and the comparison file display area, when the user views the preset display area, the contents displayed in the reference file display area and the comparison file display area will not change. In this case, if the user wants to view the specific content in the reference file and the comparison file in combination with the difference details, the user needs to drag the scroll bars of the reference file display area and the comparison file display area respectively, and the operation is cumbersome . In order to improve the efficiency for users to view differences based on the difference details, the embodiment of the present invention can bind the ID with the corresponding difference information in the difference details; when receiving the second synchronous positioning instruction triggered based on the difference details Obtaining the IDs bound to the difference information in the difference details corresponding to the second synchronous positioning instruction; synchronously highlighting the difference texts at all DIV element position information bound to the obtained IDs.

Wherein, the second synchronous positioning instruction is an instruction generated when the user clicks on a preset display area. When the client receives the second synchronous positioning command, it will activate the ID bound to the difference information in the difference details corresponding to the second synchronous positioning command. For the component corresponding to the reference file or comparison file, it will judge whether the activated ID is the same as the ID contained in itself. If it contains the same ID, the difference text at the position information of the DIV element corresponding to the ID can be highlighted is displayed, and when the position information of the DIV element is not in the display area, the position information of the DIV element will be scrolled to the display area for display.

In one embodiment, no matter before or after the comparison of the two files, when the user views the two files, the scroll bar in the display area of the two files needs to be dragged respectively to realize synchronous viewing of the two files , the operation is more cumbersome. In order to improve the user's efficiency in viewing two files, the embodiment of the present invention may receive a scrolling command for the first scroll bar; determine the ratio of the currently scrolled length of the first scroll bar to the total length of the scrolling area according to the scrolling command; Scrolling the second scroll bar according to the ratio, so that the first scroll bar and the second scroll bar scroll synchronously. That is to say, for the first scroll bar, it will only scroll along with the user's dragging, but no synchronous scrolling will be performed; for the second scroll bar, it will scroll along with the scrolling of the first scroll bar.

The first scroll bar includes the scroll bar of the reference file display area or the scroll bar of the comparison file display area, and the second scroll bar includes the scroll bar of the reference file display area or the scroll bar of the comparison file display area, but is different from the The first scroll bar is different. That is to say, when the first scroll bar is the scroll bar of the reference file display area, the second scroll bar is the scroll bar of the comparison file display area; when the first scroll bar is the scroll bar of the comparison file display area, the second scroll bar The bar is the scroll bar of the reference file display area.

For example, when the user scrolls the scroll bar of the reference file display area, the client will calculate in real time the ratio of the current scrolled length of the reference file display area to the total length of the scroll area (for example, the current scrolled length is 2cm, scrolling The total length of the region is 10cm, and the ratio is 0.2), and according to this ratio, scroll the scroll bar of the comparison file display region to the ratio of 0.2 (such as the current scrolled length is 3cm, and the total length of the scrolling region is 12cm, it will scroll to 2.4cm).

Before performing difference comparison, if the user triggers synchronous scrolling, the text after synchronous scrolling can be directly displayed. After the difference comparison is performed, if the user triggers synchronous scrolling, the difference text currently scrolled to the display area can be highlighted in the comparison file and/or the reference file according to the difference comparison result, for Other text that is currently scrolled into the display area can be displayed normally without highlighting.

The file comparison method based on RPA and AI provided by the embodiment of the present invention can automatically upload the reference file and the comparison file to be compared by the RPA robot to the client, and the client can transmit the reference file and the comparison file to the server Perform a difference comparison, and finally highlight the difference text in the comparison file and/or reference file according to the difference comparison result returned by the server. It can be seen that, compared with the manual comparison of files in the prior art, the embodiment of the present invention can use the RPA robot to automatically trigger the client to send two files to be compared to the server for automatic comparison, thereby not only saving manpower, but also It allows people who originally need to do file comparison to have time to do more valuable work, and can also improve the efficiency of file comparison; compared with the prior art that requires manual marking of differences, the embodiment of the present invention can directly compare reference files and /or the difference text is highlighted in the comparison file, so that the readability of the difference text can be improved, and thus the efficiency of the user in finding the difference between the two files can be improved. Among them, when the client sends the reference file and the comparison file to the server, it can first use OCR (Optical Character Recognition, Optical Character Recognition) to identify the reference file and the comparison file, and then the two files contain multiple pages of text The documents are spliced to obtain a single-page reference text with continuous context and a single-page comparison text with continuous context. Finally, the reference text and comparison text are sent to the server for difference comparison, so that the server can directly combine the context. The two texts are compared without other processing by the server, thereby improving the efficiency and accuracy of the file comparison by the server.
