Knowledge data providing method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a knowledge data providing method and device, electronic equipment and a storage medium. The knowledge data providing method comprises the steps of obtaining aquery request statement; Performing word segmentation processing on the query request statement to obtain at least one query word; Respectively obtaining extended keywords corresponding to each queryword from an extended dictionary; Respectively matching each obtained query word or the combination of the expansion keywords corresponding to the query word with a plurality of semantic matching expressions to obtain information of a query intention; Obtaining knowledge data corresponding to the query intention from a knowledge base; Providing the knowledge data. The query request put forward ina natural language mode can be understood; The method comprises the following steps: establishing a semantic understanding framework, analyzing, carrying out demand matching on key information extracted from a query request through the established semantic understanding framework, and providing corresponding knowledge data in a knowledge base according to a query intention obtained by matching, thereby providing knowledge data accurately matched with the query intention for a query user.

Description

technical field [0001] The embodiments of the present disclosure relate to the technical field of information processing, and in particular, to a knowledge data providing method, device, electronic equipment, and storage medium. Background technique [0002] Currently, information retrieval on the Web mainly uses search engines to perform character-based keyword matching retrieval. Although the search engine avoids the blindness of users browsing network information to a certain extent and brings convenience to users, the main problem of this retrieval method is that it returns a large number of irrelevant results while missing some relevant pages. , cannot meet the needs of users to a large extent. In the face of the surge of network information, the traditional information location-based Web information representation method makes the existing information retrieval face the difficulties and dilemmas mentioned above. Contents of the invention [0003] An embodiment of t...
