Analyzing key information to be identified, dividing the key information into a plurality of target fields, and setting the target fields. After the setup is completed, the fund poster may be uploaded to process the fund poster.
In an implementation of the embodiment of the present invention, optionally, the converting the fund poster into an editable file includes: converting the fund posters in various formats into single-layer PDF files; and converting the single-layer PDF file into a double-layer PDF file through optical character recognition, and recording the coordinate of each character. The contents of the fund posters are normalized, and specifically, the fund posters in various formats, such as pictures, documents, scanning pieces and the like, are converted into single-layer PDF files and stored. Then, the text in the single-layer PDF file is recognized by Optical Character Recognition (OCR) and added to the PDF file, a two-layer PDF file is formed, and the coordinates of each Character are recorded.
S120: and carrying out layout identification on the fund poster to obtain the coordinates of layout blocks.
In the embodiment of the present invention, the fund poster is generally in columns, but the boundaries of the columns cannot be identified during OCR recognition, which easily causes an error in the reading sequence of the fund poster (for example, two sentences that are not a paragraph may be linked together), and causes the subsequent target field to be incorrectly extracted, so that it is necessary to perform layout recognition to obtain each layout block, and thus perform the extraction of the target field in each block.
In an implementation manner of the embodiment of the present invention, optionally, the performing layout identification on the fund poster to obtain coordinates of layout blocks includes: carrying out binarization processing on the fund poster; and (4) performing line scanning on the binaryzation-processed fund poster to obtain the coordinates of the layout blocks. Optionally, the step of performing binarization processing on the fund poster includes: converting the color picture of the fund poster into a black and white picture of the fund poster; correspondingly, the line scanning is carried out on the fund poster subjected to binarization processing to obtain the coordinates of the layout blocks, and the method comprises the following steps: and performing line scanning on the black and white picture by adopting OpenCV to obtain coordinates of layout blocks. The method can be used for dividing a picture into information islands containing information by OpenCV line scanning, so that block division is realized, and coordinates of layout blocks are obtained.
Therefore, by carrying out layout identification on the fund poster, the coordinates of each layout block are obtained, so that the target field can be conveniently and correctly extracted subsequently, and the information can be correctly extracted.
S130: for each layout block, each target field is extracted from the text of the editable file with coordinates located in each layout block.
In the embodiment of the invention, because the coordinates of each character in the editable file are recorded, the coordinates of each layout block are also obtained, the text of the editable file with the coordinates positioned in each layout block can be obtained, and each target field is extracted from the text.
S140: and screening the target field to obtain an extraction result.
In the embodiment of the invention, some extracted target fields do not meet the requirements, and the target fields need to be screened, so that the target fields are repeatedly extracted to obtain the extraction result.
In an implementation manner of the embodiment of the present invention, optionally, the database is queried to determine whether the target field meets the requirement; and filtering the target fields which do not meet the requirements to obtain an extraction result. Specifically, each target field is matched with a database, whether each target field is a field which needs to be extracted and meets the requirement is judged, if the target field does not meet the requirement, the target field is filtered, and the target field meeting the requirement is reserved to obtain an extraction result. For example, to extract a fund name, when setting, the target field of the extraction XX fund is set. During extraction, all fields of the XX fund are obtained, a certain 'essential fund' field may not be a fund name, a database is required to be inquired to judge whether the 'essential fund' field is the fund name, and after inquiry, the field is filtered, and a target field conforming to the fund name is reserved to obtain an extraction result, wherein the 'essential fund' field is not the fund name.
S150: and combining the extraction results to obtain structured data, and presenting the structured data.
In an implementation manner of the embodiment of the present invention, optionally, the combining the extraction results to obtain the structured data includes: and combining the extracted results based on the position relation of the layout blocks to obtain structured data. Specifically, in the extraction result, fields with specified relationships of the same layout block are combined, and structured data is formed based on the belonged relationships. For example, in the same layout block, one of fund performance x and 2021 is found, and the other of fund performance y and 2022 is found, and these two groups belong to fund performance and fund a to which the fund performance belongs. Therefore, fund a, the fund performance, two groupings under fund performance may form structured data.
