Data search matching method and device, computer equipment and storage medium

Abstract

The invention relates to the technical field of data processing, is applied to the financial industry, and particularly relates to a data search matching method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a keyword to be searched and an event graph corresponding to the keyword; according to the relationship among the nodes in the event graph, calculating the distance between the node to which the keyword belongs in the event graph and other nodes in the event graph, and extracting the nodes of which the distances are smaller than a first preset threshold value to obtain a first expansion keyword; according to the relationship among the nodes in the target encyclopedia atlas, calculating the distance between the node to which thekeyword belongs in the target encyclopedia atlas and other nodes in the target encyclopedia atlas, and extracting the nodes of which the distances are smaller than a second preset threshold value to obtain a second expansion keyword; and combining the keyword, the first extended keyword and the second extended keyword to obtain a keyword set, and performing search based on the keyword set and a preset search and analysis engine to obtain a search result.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a data search and matching method, device, computer equipment and storage medium. Background technique [0002] With the development of Internet technology, search engines are the main means of Internet-based data retrieval, and users can obtain search results through search engines. The search engine retrieves relevant information according to the keywords input by the user, and presents the retrieved relevant information to the user as search results. [0003] Most of the traditional search engines use general search engines. The general search engines perform word segmentation processing on the input retrieval content, and then perform matching according to the keywords obtained by the word segmentation processing. However, this search method using word segmentation results as keywords cannot analyze the retrieved content and realize the search for informati...

AI Technical Summary

Problems solved by technology

However, this search method using word segmentation results as keywords cannot analyze the retrieved content and realize the search for information related to the hidden content. For example, the top search results in the search results may not necessarily match the user's search topic. The accuracy of the search matching results is not high
