[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0056] To facilitate the understanding of the embodiments of the present application, further explanation will be given below in conjunction with the drawings and specific embodiments. The embodiments do not constitute a limitation on the embodiments of the present application.

[0057] Figure 1 The following is a flow chart of a method for managing certificate information based on text recognition provided by an embodiment of the present application. Figure 1 As shown, the certificate information management method based on text recognition provided in the embodiment of the present application may specifically include the following steps:

[0058] Step 110, character recognition is performed based on the acquired certificate scan to obtain key identification information, and input information input by the target object for the key identification information is obtained.

[0059] The key identification information includes text identification information and location information.

[0060] Specifically, the text recognition information usually includes key information on the certificate scan. Taking the land certificate management system as an example, the certificate scan may include but is not limited to the land property certificate, and its key information may include but is not limited to: plot code, area, real estate certificate number, etc.; the location information may include the position corresponding to each key information in the text recognition information, which may include but is not limited to page numbers, coordinates, etc. This embodiment takes the lower left corner of the certificate scan as the origin and records the coordinates of the recognized text.

[0061] In this embodiment, the target object usually refers to the user, and the input information can be understood as the relevant information input by the user for the recognized key identification information, which can correspond to each item in the text recognition information. Specifically, in addition to being used to match and verify the key identification information, the input information can also be used to supplement the missing parts in the recognized text recognition information. For example, when a certain item is missing in the text recognition information, the user can supplement the missing part. In addition, the input information can also be used to set page numbers, coordinates, etc.

[0062] In a specific implementation, this embodiment can use OCR (optical character recognition) technology to perform character recognition on the obtained certificate scan, and obtain key text information on the certificate scan as text recognition information. When performing character recognition, this embodiment can determine the position information corresponding to each item of recognized text information.

[0063] In actual implementation, this embodiment can set up a corresponding interface to display the information recognized by the OCR technology and the corresponding position through the interface. The user can fill in the corresponding information through the interface to obtain input information for subsequent information matching and verification, that is, execute step 120.

[0064] Step 120, performing information matching and information verification processing based on the key identification information and the input information to obtain information matching results, target storage information and data source tag information.

[0065] Specifically, the information matching results may include target matching results and non-target matching results, wherein the target matching results may be understood as: information matching and verification are performed on the key identification information and the input information, and the two are matched and verified correctly, that is, the text recognition information is the same as the input information, at this time a target matching result may be generated; the non-target matching results may be understood as: information matching and verification are performed on the key identification information and the input information, and a matching error occurs between the two, such as a certain item of information in the text recognition information is different from the input information filled in by the user, at this time a non-target matching result may be generated.

[0066] In this embodiment, the target storage information refers to the information to be stored, which generally includes but is not limited to text recognition information, input information, and location information, etc.; the data source tag information may include the source of the information and text positioning information. The source of the information may include but is not limited to: scanned file name, page number, and coordinates, etc., and the text positioning information may include coordinates, etc.

[0067] It should be noted that the coordinates can usually be directly determined based on the identified position information, and the scan file name can be set by the user or obtained by directly identifying the file name of the scanned document, which is not limited in this embodiment.

[0068] In the related technology, existing solutions generally obtain relevant information uploaded by enterprises. However, the information uploaded by enterprises is mostly input manually, which is prone to errors, omissions, etc., and the source of the information is not stated. Checking and verifying wrong information and / or information without indicating the source of the information requires a huge workload and it is difficult to ensure accuracy.

[0069] To solve the above problems, this embodiment matches and verifies the identified key identification information with the user input information. Specifically, for the problems of wrong filling, missing filling, etc. in the existing solutions, this embodiment uses advanced OCR technology, combined with the user selection mechanism, to realize the automatic recognition and rapid filling of scanned text information. When filling in information, the user can immediately see the text recognized by the system and compare it with the content they selected, thereby effectively avoiding input errors and omissions. In addition, for the problem of unclear information sources in the existing solutions, this embodiment automatically records the source of the information and the text location information while the user selects and fills in the information, so that the information can be used for traceability and verification in subsequent data processing and management.

[0070] Step 130, when the information matching result is a target matching result, generating traceability information based on the target storage information, the data source tag information and the location information.

[0071] The traceability information is used to form a database and conduct traceability verification.

[0072] In this embodiment, when the information matching result is a target matching result, this embodiment can use the target storage information, data source tag information and location information to build a database, that is, form a database. For the case where the database has been built, this embodiment can directly store the above information into the database, and for the certificate scan, this embodiment can store the certificate scan in the corresponding folder / database, such as the information source folder, thereby generating traceability information for traceability verification, and the traceability information can be used for traceability verification later. Therefore, this embodiment realizes the recording of information source and location information, and clarifies the source of each data, solving the problem of unclear information filling source in the prior art. Provide detailed information for subsequent data traceability, support data tracking and verification step 140, and construct an information dictionary for information management and traceability verification based on the traceability information.

[0073] The information dictionary includes dictionary information and source positioning information of the dictionary information.

[0074] Step 150: Perform secondary traceability verification and information management update based on the information dictionary and the information to be verified.

[0075] A unified description of steps 140 to 150 is provided:

[0076] In this embodiment, the dictionary information includes but is not limited to all filled-in information, and the source location information includes but is not limited to: the source and location information of the filled-in information; the information to be verified may refer to the information filled in by the user or the relevant information in the dictionary information that needs to be traced and verified.

[0077] In a specific implementation, this embodiment can use the traceability information to construct an information dictionary, and then use the information dictionary and the information to be verified to perform secondary traceability verification and information management updates. Specifically, this embodiment uses information traceability verification of each dictionary information in the information dictionary and the information to be verified to screen out the objects that need to be checked. For the key verification objects, the user can directly select the information to be checked, and then can display it through the display interface, including but not limited to displaying the data source and location of the verification information, quickly locate and verify the accuracy and source of the data, and check whether the source is filled in correctly. When performing traceability verification, this embodiment can also perform information management updates based on the modified data for the relevant data modified by the user.

[0078] Therefore, this embodiment can quickly locate information that may contain errors, reduce the workload of manual verification, and improve verification efficiency. When conducting information tracing and verification, the display interface can provide users with intuitive data source and location information, support data tracking and verification, verify data accuracy, and ensure data authenticity and reliability.

[0079] It can be seen that the embodiment of the present application uses the acquired certificate scan to perform character recognition, obtains key identification information including text identification information and location information, and obtains the input information of the target object, and then performs information matching and information verification processing on the key identification information and the input information to obtain information matching results, target storage information and data source tag information, so that when the information matching result is the target matching result, based on the target storage information, data source tag information and location information, the traceability information for forming a database and traceability verification is generated, and then according to the traceability information, an information dictionary for information management and traceability verification is constructed, so as to use the information dictionary and the information to be verified to perform secondary traceability verification and information management update. It can be seen that the embodiment of the present application effectively reduces the information mis-filling, missing filling, etc. through information matching and verification, thereby reducing the error rate of information, and constructs a storage structure for information traceability on the basis of clarifying the source of information to perform information traceability, thereby improving data verification efficiency, reducing the workload of data traceability, and improving work efficiency, and solving the problem that the existing certificate information management method cannot achieve data traceability.

[0080] Reference Figure 2 , shows a schematic flow chart of a method for managing certificate information based on text recognition provided by an optional embodiment of the present application. The method may specifically include the following steps:

[0081] Step 210, character recognition is performed based on the acquired certificate scan to obtain key identification information, and input information input by the target object for the key identification information is obtained.

[0082] The key identification information includes text identification information and location information.

[0083] In the specific implementation, refer to Figure 3 , this embodiment can construct a certificate information management system for related information management and information traceability verification. Specifically, the system can be composed of a user input terminal, an information storage terminal, a traceability verification terminal, etc. The user can submit information and scanned copies through the input terminal, and the system uses OCR technology to recognize the text in the scanned copy and match it with the information submitted by the user to form a database containing the reported information and its location information, and save the scanned copy and database folder for traceability verification, and finally store the data in the database for subsequent verification and query.

[0084] For example, at the user input end, the operation steps can be divided into: after the user logs in to the system, he enters the information submission interface; on the information submission page, the user uploads the scanned copy and fills in the required information. Figure 4 and Figure 5As shown, this embodiment can identify the information of the scanned document and display it through the interface, and the user can also input relevant information through the interface. Figure 4 or Figure 5 In the , the left part is the information input interface, and the right part is the identification display interface of the certificate scan. In addition, the user can click on a certain information and locate the corresponding position of the scanned document in the right interface according to the recorded scanned document, page number, and coordinates, such as Figure 4 or Figure 5 Example of parcel code shown.

[0085] In an optional embodiment, the embodiment of the present application performs character recognition based on the acquired certificate scan to obtain key identification information, which may specifically include: obtaining a certificate scan uploaded by the target object through the information submission page; using optical character recognition to perform text recognition on the certificate scan to obtain text recognition information; associating the text recognition information with the certificate scan, and identifying the corresponding position of the text recognition information based on the certificate scan to obtain position information; wherein the position information includes page numbers and coordinates.

[0086] In the specific implementation, this embodiment adopts advanced OCR recognition technology. Preferably, OCR recognition technology can be selected such as Tesseract or Baidu OCR, etc., to perform text recognition on the scans uploaded by users. The system can pre-process the scans through a preset OCR recognition module, and the pre-processing process can include but is not limited to: denoising, binarization, etc., to improve the recognition accuracy. The OCR recognition module performs text recognition on the pre-processed scans and extracts the text information therein. The system can associate the recognized text information with the original scans and save it as temporary data. When the user fills in the information, the system provides the recognized text for the user to choose to fill in, and this embodiment can adopt an instant feedback mechanism to display the recognition results in real time during the filling stage, and compare them with the content selected by the user to achieve the first check. Therefore, this embodiment realizes text recognition through OCR technology, reduces the burden of manual input by users, thereby reducing the risk of wrong filling and missing filling, and recognizes the positioning information of the text at the same time. In addition, the instant feedback mechanism enables users to find recognition errors in the filling stage, make corrections in time, and improve the accuracy of information filling. After utilizing the certificate information management system, this embodiment reduces the rate of incorrect filling and missing filling, and greatly reduces the incidence of incorrect filling and missing filling compared to the existing input method, which not only improves the accuracy of data processing, but also reduces the cost of subsequent data verification and correction.

[0087] In an optional embodiment, the embodiment of the present application uses optical character recognition to perform text recognition on the certificate scan to obtain text recognition information, which may specifically include: preprocessing based on the certificate scan to obtain a preprocessed scan; performing text recognition based on the preprocessed scan to obtain text recognition information.

[0088] Step 220: According to a preset matching algorithm, information matching and information verification are performed based on the key identification information and the input information to obtain an information matching result.

[0089] In a specific implementation, this embodiment can achieve information matching and information verification through a pre-set information matching module. Among them, information matching mainly matches the input information submitted by the user with the text recognized by OCR, so that the user can compare the recognized information with the content selected by himself, thereby effectively avoiding input errors and omissions, and can supplement the missing parts in the recognized information to ensure the integrity of the data.

[0090] Optionally, this embodiment performs information matching and information verification based on the key identification information and the input information according to a preset matching algorithm to obtain an information matching result, which may include: using a string matching algorithm to perform information matching based on the key identification information and the input information to obtain a matching degree; performing information verification based on the matching degree to obtain an information matching result.

[0091] In a specific implementation, the string matching algorithm adopted in this embodiment may include but not be limited to: KMP algorithm or BM algorithm, etc., as a preset matching algorithm, to match the information submitted by the user with the text recognized by OCR. The system can read the information submitted by the user and the text information recognized by OCR, and use the matching algorithm to match the information submitted by the user with the recognized text to determine the degree of matching. Based on the degree of matching, the user determines whether the submitted information is accurate. When it is determined that the information submitted by the user is accurate, the target matching result is generated.

[0092] Step 230, when the information matching result is a target matching result, target storage information is generated based on the key identification information and the input information, and data source tag information is obtained according to the data source of the target storage information.

[0093] In actual implementation, when the information matching result is the target matching result, it indicates that the information identified from the certificate scan matches the user input information, and therefore, the target storage information can be generated based on the key identification information and the input information. In particular, when the storage information is generated based on the key identification information and the input information, deduplication processing can also be performed to remove duplicate information, and the missing parts in the key identification information can be supplemented with the input information to obtain complete storage information.

[0094] In the specific implementation, this embodiment introduces an information source and location preservation mechanism. When the user selects and fills in the information, or when the information submitted by the user is determined to be accurate, the source and text location information of the information are automatically recorded to achieve data source marking, and the data source marking information is obtained for tracing and verification in subsequent data processing and management. As a result, this embodiment enables each piece of data to have clear source and location information, thereby enhancing the credibility of the data. During data review or dispute resolution, the original data source can be quickly located, improving the transparency and fairness of data processing.

[0095] Step 240: Generate traceability information based on the target storage information, the data source tag information and the location information.

[0096] The traceability information is used to form a database and conduct traceability verification.

[0097] Step 250, constructing a relational database using the traceability information according to a preset database structure, obtaining a database file, and indexing and optimizing the database file.

[0098] In the specific implementation, for the preservation of information sourced from positioning, the information storage end in the certificate information management system of this application is provided with an information database building module and an information storage module for realizing data storage, query and traceability verification. Specifically, this embodiment adopts a relational database, such as MySQL or Oracle, etc. The system uses the information submitted by the user, positioning information (scanned file name, relative path, page number, coordinates), etc. as traceability information, stores the data in the database according to the preset database structure, and indexes and optimizes the database to improve data query efficiency.

[0099] Step 260, sorting out the scanned copy of the certificate to obtain a standard format file.

[0100] In actual processing, this embodiment can organize the certificate scans submitted by users into a standard format. The system automatically generates a folder and database file for the original certificate scans, and saves them to the information source folder for subsequent tracing verification and display.

[0101] Therefore, this embodiment clarifies the source of each piece of data by recording the information source and location information, and forms an effective information source storage structure as the basis for data source traceability display, solves the problem of unclear information source, provides detailed information for subsequent data tracing, and supports data tracking and verification.

[0102] Step 270: construct an information dictionary based on the database file and the standard format file.

[0103] The information dictionary includes dictionary information and source positioning information of the dictionary information.

[0104] Step 280: Perform secondary traceability verification and information management update based on the information dictionary and the information to be verified.

[0105] In an optional embodiment, this embodiment performs secondary traceability verification and information management update based on the information dictionary and the information to be verified, which may include: the information dictionary determines the information similarity between the information to be verified and the dictionary information based on a preset similarity algorithm; filters target verification information whose information similarity is lower than a preset similarity threshold from the information to be verified, the target verification information including attribute information; displays the target verification information through a display interface, and obtains verification operation data when the target object performs secondary traceability verification on the target verification information, the verification operation data including processing verification operations and update data corresponding to the processing verification operations; and performs information management update based on the verification operation data.

[0106] In the specific implementation, this embodiment uses relevant information to construct an information dictionary, which contains all the filled-in information and its source and location information. In the secondary verification stage, the system can calculate the similarity between the information to be verified and the information in the dictionary based on the dictionary, and select attributes with low similarity as the key verification objects. The user can directly select the information to be verified, quickly locate and verify the accuracy and source of the data, and check whether the source is correct.

[0107] In actual implementation, refer to Figure 3, this embodiment can realize the construction of information dictionary, similarity calculation module, screening and display at the traceability verification end. Specifically, the similarity calculation module calculates the similarity between the information to be verified and the information in the dictionary according to a preset similarity calculation algorithm (such as cosine similarity, Jaccard similarity, etc.). Then screening and display are performed. In the secondary verification stage, the system automatically filters out attributes with low similarity. For example, a similarity threshold can be preset, and attributes with similarity lower than the similarity threshold are filtered out and displayed to the user through the interface, and the function of quickly locating to the corresponding position in the scan is provided. The user can perform multiple operations, including but not limited to: add, delete, modify, check, etc., and can update relevant information according to the user's operation. This embodiment supplements the display method of data source tracing, which can effectively track and verify the source and accuracy of data, highlight the correlation between different data attributes, and improve the efficiency and accuracy of manual verification.

[0108] Therefore, this embodiment uses the information dictionary to screen out attributes with low similarity as key verification objects based on similarity calculation. Users can directly select the information to be verified and check whether the source is correct, thereby improving the efficiency and accuracy of information verification. After using the system of the present invention, the efficiency of information verification is improved compared with the traditional manual verification method, and the accuracy rate is also significantly improved. This improvement is mainly due to the introduction of similarity screening and traceability viewing functions, which enable users to quickly locate the information that needs to be verified and verify its accuracy.

[0109] In addition, the certificate information management system in this embodiment mainly adopts a modular design, and each module is relatively independent and easy to expand and integrate. This provides users with greater flexibility and allows them to selectively introduce or expand functional modules according to actual needs. The modular design allows this application to easily adapt to different application scenarios and changes in requirements. Users can flexibly adjust and optimize system functions according to actual business needs, thereby achieving more efficient information management.
