It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Referring to fig. 1, an electronic document filing method provided in the embodiment of the present application specifically includes the following steps:
s100: an electronic document to be archived is received.
The electronic documents to be filed can be various electronic documents, including official documents, referee documents, administrative determinants, personnel information registration lists, hospital diagnosis and treatment records, paper articles and other various electronic documents to be filed.
S200: and analyzing the electronic document to be filed by adopting an image segmentation algorithm to obtain layout structure information.
Image segmentation (image segmentation) is an important research direction in the field of computer vision, and is an important part of image semantic understanding. Image segmentation refers to a process of dividing an image into several regions having similar properties, and from a mathematical point of view, is a process of dividing an image into mutually disjoint regions. In recent years, with the deep learning technology, the image segmentation technology has been developed dramatically. The electronic document can be segmented according to file elements and distribution through different image segmentation algorithms. Electronic documents to be filed usually have a certain layout structure. For example, the report data generated based on online filling usually has certain standard requirements. For another example, government agencies and documents typically have strict formatting specifications. Both papers and documents have certain format standards. In addition, documents of interest formed in specific fields such as medical treatment, judicial law enforcement, and the like have a fixed format. Therefore, the layout structure can be analyzed by adopting an image segmentation algorithm to obtain layout structure information.
Further, in a preferred embodiment provided by the present application, an image segmentation algorithm is used to analyze an electronic document to be archived, and to obtain layout structure information, which specifically includes:
acquiring the distribution characteristics of the page elements of the electronic document to be filed and carrying out standardization processing;
according to the document page element distribution characteristics subjected to standardization processing, an image segmentation algorithm is adopted to segment the electronic document page into a plurality of layout areas;
aggregating the mapping relation between the element distribution characteristics of the layout area and the layout type, and determining the mapping relation between the element distribution characteristic sample space and the layout type sample space;
acquiring layout structure information according to the distribution characteristics of page elements of an electronic document to be filed, wherein the layout structure information comprises layout categories and coordinate information;
wherein the image segmentation algorithm comprises at least one of maskrcnn, fastrcnn and u-net.
Specifically, different electronic documents often have different layout structures, and different layouts distribute different characters or other content information to show different page element distribution characteristics. For example, titles are usually located in the top area of an electronic document, money drops and time are usually located in the bottom area of the electronic document, and different content elements (e.g., characters, pictures, charts, tables) show different element distribution characteristics on the electronic document.
The method comprises the steps of obtaining the distribution characteristics of the page elements of the electronic document to be filed and carrying out standardization processing, wherein the purpose of the standardization processing is to convert the distribution characteristics of the page elements of the electronic document into characteristics which can be identified by an algorithm. For example, information such as the spatial orientation and size of an area occupied by a certain page element, and the orientation and size of distribution of specific content in the area is standardized to obtain an association array, which is determined as a specific element block that can be divided and identified. And (4) segmenting the electronic document by using a mask rcnn/fastrcnn/u-net algorithm, and segmenting the electronic document into different layout parts according to pixels. The division of the layout area takes the principle of having standardized uniform element characteristics and content information. Different element distribution characteristics have different space orientations (coordinate information) and layout content information, and correspond to different layout types. By aggregating the mapping relationship between the element distribution characteristics of a large number of layout areas and the layout types, the mapping relationship between the element distribution characteristic sample space and the layout type sample space can be determined. And analyzing the element distribution characteristics of the electronic document page to be filed according to the mapping relation between the element distribution characteristic sample space and the layout type sample space, and acquiring layout structure information. The layout structure information includes a layout type and coordinate information.
The maskrcnn, fastrcnn and u-net are all existing image segmentation algorithm tools, and the specific methods thereof are elaborated in relevant documents. And will not be described in detail herein.
Further, in a preferred embodiment provided by the present application, the layout structure information includes a layout type and coordinate information, where the layout type includes at least one of a background, a title, a text, a picture, a table, a header, and a footer.
It is understood that electronic documents usually have layout settings such as background, title, text, header, footer, etc., and there are elements such as text, picture, and table in the document. Different layout areas and position information correspond to different layout types and have different element distribution characteristics. The electronic document is divided according to the above elements, and the layout structure information can be acquired by recognizing the image information and the position coordinate information of the different layout areas. For example, the background usually covers the entire document page area, the header usually is located at the top center of the document, the body usually is relatively regular segmented text, and the table has a distinct regular border. The background, the title, the text, the picture, the table, the header and the footer are analyzed by an image segmentation algorithm, so that the information of different page types and coordinates can be obtained.

After the first area of the layout is determined, the first area of the layout is identified by adopting an OCR technology, content information of the corresponding area is obtained, and first classification information is generated according to the content information. For example, the money drop part at the bottom of the page is determined as a first area of the layout, and the date of the money drop part extracted after recognition is first classification information. Or determining the title part at the top of the page as a first region of the layout, identifying and extracting key fields of the title part related to file types (official documents such as notices and decisions, and official documents such as civil judgment, criminal judgment, administrative judgment, official documents and the like) to generate first classification information.
