Description

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

Technical Field

The embodiment of the invention relates to the technical field of process automation, in particular to a file comparison method, device, equipment and storage medium based on RPA and AI.

Background

RPA (Robotic Process Automation, robot process automation) is a process task automatically executed according to rules by a specific "robot software" that simulates the operation of a human on a computer.

AI (ARTIFICIAL INTELLIGENCE ) is a new technical science to study, develop theories, methods, techniques and application systems for simulating, extending and expanding human intelligence.

RPA has unique advantages: low code, non-intrusive. The low code means that the RPA can operate without a very high IT level, and business personnel without programming can develop the flow; non-intrusive means that the RPA can simulate human operation without a software system open interface. However, conventional RPA has certain limitations: can only be based on fixed rules and application scenarios are limited. With the continuous development of the AI technology, the limitations of the traditional RPA are overcome by the deep fusion of the RPA and the AI, and the values of the labor force are greatly changed by the RPA+AI=hand work+head work.

In daily work, it is often necessary to compare two versions of a contract, legal, etc. file to determine what changes have occurred in the newly created file relative to the original file. However, currently, when the files are compared, two files to be compared need to be manually acquired, and then the difference between the manual comparison and the manual marking is carried out. When more files need to be compared or the number of pages of the files to be compared is more, the repeated low-value file comparison labor is needed by staff, so that a large amount of working time is occupied, and the working efficiency is low.

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

s100, receiving the reference file and the comparison file uploaded by the RPA robot.

Specifically, the embodiment of the invention can configure the RPA program (which can be integrated with or embedded into the client or can be independent of the client) in the electronic equipment capable of logging in the client, so that the electronic equipment can simulate the mouse and keyboard operation of a user to automatically log in the client according to the rule set in the RPA program, trigger the client to generate a file comparison request comprising the reference file and the comparison file through accessing the client, and send the file comparison request to the server, thereby enabling the server to compare the difference between the reference file and the comparison file. When a client is logged in, the client can pop up a login interface containing the verification code image, in this case, the RPA robot can perform OCR (optical character recognition) on the verification code image to obtain the verification code content in the verification code image, and input the verification code content into a corresponding editing box, so that the client is successfully logged in.

The reference file and the comparison file can be stored in the client, can be stored in other storage spaces of the electronic equipment, and can be paper files. When the file is stored in other storage spaces of the electronic device, the RPA robot can search the reference file and the comparison file from the other storage spaces and upload the reference file and the comparison file to the client, for example, the two files are uploaded to the client by clicking an upload button, or the two files are dragged to a designated area by a dragging mode to realize file uploading, or other uploading modes are adopted. When the reference file and/or the comparison file is a paper file, the RPA robot may first convert the paper file into an image file or into a text file (i.e., an editable file composed of text contents in the paper file) by using the OCR technology, and then upload the image file or the text file to the client by using the above method.

When the client receives the reference file and the comparison file uploaded by the RPA, the reference file and the comparison file can be rendered so as to show the uploaded file to the user. Specifically, when the reference file and/or the comparison file is a word file, the word file can be converted into a PDF file, then rendering is performed by using a rendering library of the client, and when the PDF file is a multi-page file, multi-page rendering is performed; when the reference file and/or the comparison file are/is picture files except tiff format, rendering can be performed by using a rendering library carried by the client; when the reference file and/or the comparison file is a picture file in tiff format, a proprietary rendering library in tiff format may be utilized for rendering. When the word file is converted into the PDF file, the PDF file can be transmitted to the server by the client to execute conversion operation and then fed back to the client by the server to be rendered.

S110, the reference file and the comparison file are sent to a server.

After receiving the reference file and the comparison file uploaded by the RPA robot, the client can receive a file comparison instruction triggered by the RPA robot, then directly generate a file comparison request comprising the reference file and the comparison file according to the file comparison instruction, and send the file comparison request to the server so that the server can compare the reference file and the comparison file differently. However, after the server receives the reference file and the comparison file, the server needs to identify the text in the two files to perform differential comparison, and if more clients send file comparison requests to the server, the efficiency of the server in performing file comparison is reduced. In order to reduce the burden of a server and improve the file comparison efficiency, the embodiment of the invention can firstly identify the reference file and the comparison file by utilizing OCR by a client to obtain at least one page text of the reference file and at least one page text of the comparison file, and then send the identified text to the server for differential comparison.

In practical application, if at least one page text of the reference file is directly compared with at least one page text of the comparison file in a single page manner, namely, the nth page of the reference file is compared with the nth page of the comparison file, and the association relationship among the pages is not concerned, the situation that the comparison result is inaccurate is easy to occur. For example, the reference file includes two texts, and a single-page comparison method is adopted to compare the two texts, so that the second text of the reference file is different from the second text of the comparison file, and the reference file does not have a third text, so that the third text of the comparison file does not exist in the reference file, that is, the single-page comparison method is adopted, and the overall comparison result is that the two files are different except the first text.

In order to avoid the problem of inaccurate comparison results, the embodiment of the invention identifies the reference file and the comparison file by utilizing OCR at the client, and after at least one page text of the reference file and at least one page text of the comparison file are obtained, firstly performs text splicing, and then sends the spliced text to the server. Specifically, when a target file is a file containing multiple pages of texts, splicing the multiple pages of texts of the target file into a continuous context page text to obtain a target text, and when the target file is a file containing a single page of text, acquiring the single page of text from the target file as the target text, wherein the target file comprises a reference file or a comparison file, when the target file is the reference file, the target text is the reference text, and when the target file is the comparison file, the target text is the comparison text; and sending the reference text and the comparison text to the server.

Wherein, the context continuous means that the sequence of the original characters is kept. The specific method for splicing the multi-page text of the reference file or the comparison file into the context continuous one-page text can be to splice the multi-page text in sequence according to the paging sequence of the reference file or the comparison file, so as to obtain the context continuous one-page text.

It should be added that, in order to improve the communication security between the client and the server, the server may 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, the client can also carry the user information of the client, so that the server authenticates the client according to the user information, and when the authentication is determined to pass, the reference file and the comparison file are subjected to differential comparison. The user information can be a client account number, a mobile phone number bound with the client account number, a user grade or other information, and the specific content of the user information is not limited and can be determined according to specific conditions. There are a variety of methods for authenticating user information, including but not limited to the following: (1) Matching the user information with a user list with authority, if the matching is successful, determining that the user corresponding to the user information has authority, namely authentication is passed, and if the matching is failed, determining that the user corresponding to the user information has no authority, namely authentication is failed; (2) Judging whether the user grade in the user information exceeds a preset grade, if so, passing authentication, and if not, failing authentication.

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

After receiving the reference file and the comparison file, the server can compare the reference file with the comparison file in a different way according to a preset comparison algorithm. Specifically, the reference text and the comparison text may be compared according to a preset comparison unit, so as to obtain a comparison pair result for each preset comparison unit. In the process of comparing the reference text and the comparison text according to the preset comparison unit, if the content of the reference sub-text being compared (the reference text of the preset comparison unit) is identical to that of the comparison sub-text (the comparison text of the preset comparison unit), the corresponding comparison sub-result is determined to be identical in content; if the reference sub-text which is being compared is determined to not exist in the comparison text, determining the corresponding comparison sub-result as content deletion; if it is determined that the aligned pair text does not exist in the reference text, the corresponding aligned pair result is determined as the content increase. In practical applications, the difference between two texts should include content modification in addition to content identity, content deletion and content addition. Therefore, in order to enable the user to more intuitively see the difference of the comparison text relative to the reference text, the comparison pair results between the first comparison pair result and the second comparison pair result can be combined into one comparison pair result if the first comparison pair result and the second comparison pair result are the same in content and the comparison pair results between the first comparison pair result and the second comparison pair result comprise content deletion and content addition and do not comprise the same in content, and the combined comparison pair results are content modification. The size of the preset comparison unit can be determined according to practical situations, and can be a phrase, a sentence, a paragraph and the like.

When the two texts are compared, the method can be used for judging whether the characters or the words used by the text content are the same or not simply, and can be used for carrying out semantic analysis on the reference sub-text and the comparison sub-text by combining an NLP technology, and when the reference sub-text and the comparison sub-text have the same meaning but the used characters or words are different, the corresponding comparison sub-text can be determined to be the same in content. In addition, the embodiment of the invention can also support the self-defined filtering rule, and ignore meaningless differences, namely, when differences meeting the preset filtering rule exist in the differences between the reference sub-text and the comparison sub-text, the differences meeting the preset filtering rule are ignored. For example, it may be set that the presence or absence of a sentence "does not affect the comparison result. When the server sends the difference comparison result to the client, the server can also send the ignored difference, so that the client can display the ignored difference to the user.

When the comparison sub-result is a content addition, a content deletion or a content modification, one piece of difference information may be generated for the comparison sub-result so that after all the difference information is obtained, all the difference information is fed back to the client. Each piece of difference information comprises a difference type, a difference text in the reference file, a difference text in the comparison file, difference position information of the difference text in the reference file and difference position information of the difference text in the comparison file, wherein the difference position information comprises a page identification of a page to which the difference text belongs and coordinate information of the page to which the difference text belongs. A comparison sub-result corresponds to a piece of difference information, and the difference types comprise content addition, content deletion and content modification. The page identification is used to indicate what page is in the entire file. For the coordinate information, a coordinate system may be established for each page, with the first character position of each page as the origin, and the horizontal and vertical axes, respectively, right and left, so that corresponding coordinates may be generated for each character in the page.

In one embodiment, after the client sends the reference file and the comparison file to the server, the server may add the task of comparing the reference file and the comparison file to the task queue, store the task state of the comparison task and the task state of the comparison task to the task database, and update the task state in the task database in time when the task state of the comparison task changes. The client can receive a comparison task state query instruction triggered by the RPA robot and send the comparison task state query instruction to the server, so that the server queries the task state of the comparison task corresponding to the comparison task state query instruction from the task database and feeds back the queried task state to the client. Wherein, when the comparison task is not executed, the task state may be unprocessed, when the comparison task is being executed, the task state may be in process, and when the execution of the comparison task is completed, the task state may be completed.

In addition, the server can actively feed back the differential comparison result to the client, and can also passively feed back the differential comparison result to the client. The specific implementation manner of passively feeding back the difference comparison result to the client may be: the client receives a comparison result query instruction triggered by the RPA robot, sends the comparison result query instruction to the server, and sends a corresponding difference comparison result to the client according to the comparison result query instruction.

The specific implementation mode that the RPA robot triggers the client to send the comparison result query instruction or the comparison task state query instruction includes, but is not limited to, that the RPA robot triggers the client to generate and send a corresponding instruction by clicking a comparison result query button or a comparison task state query button on the client.

S130, according to the difference comparison result, highlighting a difference text in the comparison file and/or the reference file.

The highlighted difference text in the comparison file is a text of the comparison file with a difference relative to the reference file, and the highlighted difference text in the reference file is a text of the reference file with a difference relative to the comparison file. The manner of highlighting includes, but is not limited to, combinations of one or more of the following: bold font, change font color, increase font ground color, highlight font, increase font, change to italics, increase underlining, increase strikethrough, etc. When the difference comparison result includes a plurality of difference types, the different difference types may be highlighted in the same manner or in different manners.

The specific implementation manner of the step can be as follows: converting the coordinate information into DIV element position information; when the DIV element position information enters a display area of the file, highlighting a difference text at the DIV element position information in the page indicated by the page identification according to a difference type corresponding to the DIV element position information and the page identification corresponding to the DIV element position information. Where DIV is a localization technique in cascading style sheets, DIV elements are elements used to provide structure and context for block-level (block-level) content within an HTML document. For the reference file and the comparison file, a display area is respectively encapsulated, and one display area is a component, for example, two display areas arranged from left to right can be encapsulated on an interface to respectively display the reference file and the comparison file, and when the reference file and/or the comparison file have more texts and cannot be fully displayed at one time, the rolling display function of the rolling bar can be increased.

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, only the deleted text may be highlighted in the reference file, or the text before content deletion and the text remaining after content deletion may be highlighted respectively, that is, the difference text contained in the difference information in the reference file and the difference file in the comparison file are highlighted. If the difference type contained in the current difference information is content increase, the increased content may be highlighted only in the comparison file, or the text before the content increase and the text after the content increase may be highlighted respectively, that is, the difference text contained in the difference information in the reference file and the difference file in the comparison file are both 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, namely, the difference text contained in the difference information in the reference file and the difference file in the comparison file are highlighted.

By way of example, FIG. 2 is a partial text content of a reference file and a comparison file, in which differential text may be highlighted directly, a user may browse by dragging a scroll bar of the reference file and the comparison file. Wherein, the text with bold and underline refers to the text which is modified, the text with slant and enlarged refers to the text which is added in the comparison file, and the text with deletion line refers to the text which is deleted in the comparison file.

In one embodiment, when the user needs to check and view a difference, the user needs to drag the scroll bars of the two files to view the two files, and the operation is complicated. In order to improve the efficiency of checking differences for users, the embodiment of the invention can generate an ID (Identity Document, identity card identification number) according to DIV element position information of a difference text in the reference file, DIV element position information of a difference text in the comparison file and a difference type aiming at the same piece of difference information, respectively bind the ID with the DIV element position information of the difference text in the reference file and the DIV element position information of the difference text in the comparison file, and synchronously highlight the difference text at all DIV element position information bound with the ID corresponding to the first synchronous positioning instruction when a first synchronous positioning instruction triggered based on the reference file or the comparison file is received.

Specific implementations of generating an ID include, but are not limited to: and splicing 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 according to a preset sequence to obtain a character string. Wherein different disparity types may be represented using different characters, e.g. "content delete", "content add" and "content modify" may be represented using "1", "2" and "3" in sequence. The first synchronization positioning instruction is an instruction generated when the user clicks on the reference file or the display area of the alignment file. When the client receives the first synchronous positioning instruction, the corresponding ID is activated. For the components corresponding to the reference file or the comparison file, whether the activated ID is the same as the ID contained in the reference file or not is judged, if the activated ID contains the same ID, the difference text at the DIV element position information corresponding to the ID can be highlighted, and when the DIV element position information is not in the display area, the DIV element position information is scrolled to the display area for display. For example, for the same piece of difference information, when the difference text "electronic device" in the reference file is located on page 2 of the reference file and the difference text "computing terminal" in the comparison file is located on page 3 of the comparison file, the user clicks at the text "electronic device" on page 2 of the reference file, the client automatically synchronizes so that the comparison file automatically scrolls to page 3 and highlights the text "computing terminal".

In one embodiment, in order to provide a way for a user to view differences more, the embodiment of the invention can display difference details in a preset display area according to the difference comparison result, wherein the preset display area is an area except a reference file display area and a comparison file display area, and the difference details comprise difference types in each piece of difference information, difference texts in the reference file and difference texts in the comparison file. In addition, the difference comparison results can be summarized, and the summarized results are displayed in display areas except for the reference file display area, the comparison file display area and the preset display area. The summarized result comprises the total number of the difference information and the paging identification where the difference information is located. For example, the summary result is "found after alignment that there are differences on pages 1, 3, 5, 8 of the reference file, and there are 20 differences between the two files.

For example, as shown in fig. 3, when the client displays the difference, the client may not only highlight the difference text in the reference file and/or the comparison file, but also display the comparison result on the right side. The upper half of the comparison result is the overall comparison result (namely the summarized result), and the lower half is the detailed comparison result (namely the difference detail). The user can browse the difference details by dragging the scroll bar of the detailed comparison result display area.

Because the preset display area is independent of the reference file display area and the comparison file display area, when a user views the preset display area, the contents displayed by the reference file display area and the comparison file display area are not changed. In this case, if the user wants to view specific contents in the reference file and the comparison file in combination with the difference details, the user is required to drag the scroll bars of the reference file display area and the comparison file display area, respectively, so that the operation is complicated. In order to improve the efficiency of a user to view differences based on difference details, the embodiment of the invention can bind the ID with the corresponding difference information in the difference details; when a second synchronous positioning instruction triggered based on the difference detail is received, acquiring an ID (identity) bound by difference information in the difference detail corresponding to the second synchronous positioning instruction; and synchronously highlighting the difference text at the position information of all DIV elements bound with the acquired ID.

The second synchronous positioning instruction is an instruction generated when a user clicks a preset display area. When the client receives the second synchronous positioning instruction, the ID of the difference information binding in the difference detail corresponding to the second synchronous positioning instruction is activated. For the components corresponding to the reference file or the comparison file, whether the activated ID is the same as the ID contained in the reference file or not is judged, if the activated ID contains the same ID, the difference text at the DIV element position information corresponding to the ID can be highlighted, and when the DIV element position information is not in the display area, the DIV element position information is scrolled to the display area for display.

In one embodiment, before or after comparing two files, when a user views the two files, the user needs to drag the scroll bars of the two file display areas respectively to realize synchronous viewing of the two files, which is complex in operation. In order to improve the efficiency of a user to review two files, the embodiment of the invention can receive a scrolling instruction aiming at a first scroll bar; determining the proportion of the current rolled length of the first rolling bar to the total length of the rolling area according to the rolling instruction; and scrolling a second scroll bar according to the proportion, so that the first scroll bar and the second scroll bar synchronously scroll. That is, for the first scroll bar, only the drag of the user is followed, and the synchronous scroll is not performed, and for the second scroll bar, the scroll is performed along with the scroll of the first scroll bar.

The first scroll bar includes a scroll bar of a reference file display area or a scroll bar of an alignment file display area, and the second scroll bar includes a scroll bar of a reference file display area or a scroll bar of an alignment file display area, but is different from the first scroll bar. That is, when the first scroll bar is a scroll bar of the reference file display area, the second scroll bar is a scroll bar of the alignment file display area; when the first scroll bar is a scroll bar that is aligned with the file display area, the second scroll bar is a scroll bar that is referenced to the file display area.

For example, when the user scrolls the scrollbar of the reference file display area, the client calculates in real time the ratio of the currently scrolled length of the scrollbar of the reference file display area to the total length of the scrolled area (for example, the currently scrolled length is 2cm, the total length of the scrolled area is 10cm, and the ratio is 0.2), and scrolls the scrollbar of the comparison file display area to the ratio of 0.2 according to the ratio (for example, the currently scrolled length is 3cm, and the total length of the scrolled area is 12cm, and scrolls to the position of 2.4 cm).

Before the difference comparison is carried out, 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, and for other texts currently scrolled to the display area, conventional display is performed without highlighting.

According to the file comparison method based on the RPA and the AI, the reference file and the comparison file to be compared can be automatically uploaded to the client by the RPA robot, the reference file and the comparison file are transmitted to the server by the client for differential comparison, and finally the differential text can be highlighted in the comparison file and/or the reference file according to the differential comparison result returned by the server. Compared with the prior art requiring manual comparison of files, the file comparison method and device can automatically trigger the client to send two files to be compared to the server by using the RPA robot to perform automatic comparison, so that manpower can be saved, personnel who originally need to do file comparison can do more valuable work in time, and the file comparison efficiency can be improved; compared with the prior art requiring manual marking of the difference, the embodiment of the invention can directly highlight the difference text in the reference file and/or the comparison file, thereby improving the readability of the difference text and further improving the efficiency of searching the difference between the two files by a user. When the client sends the reference file and the comparison file to the server, the reference file and the comparison file can be identified by utilizing OCR (Optical Character Recognition, optical character identification), then the files containing the multi-page text in the two files are subjected to text splicing to obtain a single-page continuous reference text and a single-page continuous comparison text, and finally the reference text and the comparison text are sent to the server for differential comparison, so that the server can directly connect the contexts to compare the two texts without other processing of the server, and further the efficiency and the accuracy of the server for comparing the files can be improved.
