[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0052] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script.

[0053] In the current office system, electronic files are also used for circulation. After entering the system, electronic files will be stored in the database. Specifically, some are in the form of pictures, and some are in the form of documents. In the long-term use process, older documents will be generated, so the memory occupied will become more and more. The data memory occupied by the office files gradually accumulated in the existing office system is gradually increasing, and the memory usage is high.

[0054] The present invention classifies all documents, thereby decomposing the long-unused electronic documents contained therein, thereby constructing a standard database and converting the electronic documents into combined documents composed of standard data. Therefore, when storing, only the type and position of the standard data in the electronic documents need to be stored. When it is necessary to retrieve, the electronic documents can be restored according to the type and position of the standard data in the electronic documents, which not only ensures the normal use of the electronic documents but also saves data occupancy.

[0055] like Figure 1 FIG. 1 is a flowchart of an electronic document management method provided by an embodiment of the present invention, wherein the method comprises:

[0056] S100, constructing a standardized database, obtaining an electronic document to be stored, wherein the electronic document to be stored is an image or an editable text, and the standardized database stores standard element data.

[0057] In this step, a standardized database is constructed, in which standard element data is stored. In this process, all data that may be involved in the current electronic document are standardized and stored in the standardized database. For example, for an electronic document, its main contents include title, main content, signature, seal, signature and other information. The title and main content are variable, so they are directly used as a separate standard element data. The signature, seal and signature and other information can be used universally. The number of signatures, seals and signatures contained in a system is limited, so they can be used universally among different electronic documents and are also used as universal standard element data.

[0058] S200, reading the electronic document to be stored, performing content analysis on the electronic document to be stored, and extracting document analysis results.

[0059] In this step, the electronic documents to be stored are read and retrieved, and then the contents are preliminarily divided into different areas through image recognition, and the screenshots obtained by the division are used as document analysis results, such as dividing the electronic documents into title, main content, signature, seal, and signature areas, which are then entered into the document analysis results.

[0060] S300, querying a standardization database according to the document analysis result to determine a standard element set contained in the current electronic document to be stored.

[0061] In this step, the standardization database is queried based on the document analysis results, and then the document analysis results are compared with all the standard element data in the standardization database to determine the standard element data contained in each document analysis result. The standard element set contained in the current electronic document to be stored can be determined. In this process, the title and main content are stored in the standardization database as separate standard element data.

[0062] S400, querying a preset standard element table according to the standard element set, determining each standard element identifier, storing the standard element identifier and its position information, and deleting the electronic document to be stored, wherein the standard element identifier and its position information are used to restore the electronic document to be stored.

[0063] In this step, the preset standard element table is queried according to the standard element set, and each standard element data in the standardization database is numbered or a unique identifier is set for it, so as to determine the standard element identifier corresponding to each standard element data through query, and determine the location of the record title, main content, signature, seal, and signature area in the original electronic document, that is, obtain the location information, delete the electronic document to be stored, and store the standard element identifier and its location information. The stored standard element identifier and its location information are used to restore the electronic document to be stored; when storing the standard element identifier and its location information, it is encrypted.

[0064] like Figure 2 As shown, as a preferred embodiment of the present invention, the step of restoring the electronic document to be stored specifically includes:

[0065] S501, determining the document type according to the standard element identifier, and retrieving the corresponding blank document from the standardization database.

[0066] In this step, the document type is determined based on the standard element identifier, and then the corresponding blank document is retrieved from the standardized database, that is, the type of electronic document that needs to be replied is first determined, and then the corresponding blank image or blank document or table is retrieved.

[0067] S502: Retrieve corresponding standard element data from a standardization database according to the standard element identifier.

[0068] In this step, the corresponding standard element data is retrieved from the standardization database according to the standard element identifier. Since each type of standard element data corresponds to a standard element identifier, the data is retrieved by querying.

[0069] S503, restoring the standard element data to the corresponding position in the blank document according to the position information, to obtain the electronic document to be stored.

[0070] In this step, the standard element data is restored to the corresponding position in the blank document according to the position information. The position information records the specific position of each standard element data in the electronic document. Specifically, it can be the pixel position, the length position, or the table position.

[0072] S201, retrieve the electronic document to be stored, and retrieve the standard data reference from the standardization database.

[0073] In this step, the electronic document to be stored is retrieved. In order to extract relevant information from the electronic document, the standard data reference is retrieved from the standardization database. The standard data reference records the main features of information such as title, main content, signature, seal, and signature.

[0074] S202, converting the electronic official document to be stored into an official document image, performing content recognition on the official document image, and obtaining a content recognition result.

[0075] In this step, the electronic document to be stored is converted into a document image. If the electronic document to be stored is an image, the step of converting the electronic document to be stored into a document image is skipped. This step is used to convert the electronic document into a unified format, and then the content of the document image is identified by reference to standard data, that is, fuzzy contrast is used to determine whether the document image contains information such as title, main content, signature, seal, and signature, and obtain content recognition results.

[0076] S203, intercepting the document image according to the content recognition result to obtain a document analysis result, wherein the document analysis result includes location information of the intercepted image.

[0077] In this step, the official document image is captured according to the content recognition result, and the location of the title, main content, signature, seal, and other information is determined through fuzzy comparison. The official document image is captured according to the content recognition result to obtain the document analysis result, which includes the location information of the captured image.

[0078] like Figure 4 As shown, as a preferred embodiment of the present invention, the step of querying the standardization database according to the document analysis result to determine the standard element set contained in the current electronic document to be stored specifically includes:

[0079] S301, reading the document analysis results one by one, comparing the document analysis results with all the data in the standardization database, and obtaining comparison results.

[0080] In this step, the document analysis results are read one by one, the background of the captured image is removed, and then it is compared with all the data in the standardization database to find the corresponding standard element data.

[0081] S302, retrieve corresponding standard element data according to the comparison result, and enter the standard element data and corresponding position information into a standard element set.

[0082] In this step, the corresponding standard element data is retrieved according to the comparison results, and the position information corresponding to the standard element data needs to be collected and entered into the standard element set together.
