Embodiment Construction
[0053] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific diagrams.
[0054] refer to figure 1 , a method for extracting key information from a research report, including:
[0055] S1. Determine the target detection result: obtain the research report file, perform target detection on the research report file through the preset layout analysis model, and obtain the target detection result. The target detection result is the position and category information of multiple targets in the research report file.
[0056] The research report file in this step is a research report issued by a securities company, and it is mostly published as a PDF file. For a research report PDF file, before performing target detection, it is necessary to convert the format first, and then use the layout analysis model to perform target detectio...

The invention belongs to the technical field of data processing, and in particular relates to a method for extracting key information from research reports and related equipment. The methods include: obtaining the research report file, performing target detection on the research report file, and obtaining the target detection result, the target detection result is the position and category information of multiple targets in the research report file; analyzing the research report file, and obtaining the research report file According to the target detection results, the characters in the same target are merged to obtain the text information and the corresponding coordinate position; the text information is classified by subject through the preset text classification model, and the research Report files are stored and output according to subject classification. The present invention can classify the research report files of different themes, and by classifying the research report topics, can quickly screen out the research report category that one pays attention to, and ignore irrelevant research reports.
Description
technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to a method for extracting key information from research reports and related equipment. Background technique [0002] With the rapid development of the Internet, in order to facilitate more investors to invest, many securities companies or investment institutions will regularly make a professional research report on listed companies. At present, the number of research reports is increasing day by day, and covers different topics such as company research, industry research, macro research, investment strategy, morning meeting report, fund research, etc. How to select the research reports you care about from the massive research report documents, Extracting effective information for fast reading is an urgent problem to be solved. [0003] The Chinese patent "CN201710067220 An Information Extraction Method and Device for PDF Files" obtains the title, text, chart, c...
