Problems solved by technology

[0002] In related technologies, when users search, they usually need to turn multiple pages to obtain the knowledge they are really interested in, and the retrieval cost is relatively high.
In addition, the content of the search results has a low correlation with the search terms, and some cheating webpages even provide false index words to mislead the recall and affect the user experience

Abstract

The invention provides a content retrieval method, a retrieval library construction method, devices and equipment, and relates to the technical field of artificial intelligence such as knowledge maps, intelligent search and natural language processing. The content retrieval method comprises the following steps: obtaining retrieval information; target entity information matched with the retrieval information is determined from multiple pieces of chain finger information in a retrieval library, the chain finger information is information obtained through chain finger extraction entity information and knowledge graph entity information, and the extraction entity information is information obtained after knowledge extraction is conducted on the entity content; and obtaining entity content corresponding to the target entity information from the retrieval library. According to the content retrieval method disclosed by the invention, knowledge of webpage information can be realized, a user can accurately obtain interested knowledge, the problem that the correlation between the content of the retrieval result and the retrieval word is relatively low can be effectively solved, the retrieval efficiency can be improved, and the user experience can be effectively improved.

Description

technical field [0001] The present disclosure relates to the field of data processing technology, specifically to the field of artificial intelligence technologies such as knowledge graphs, intelligent search, and natural language processing, and in particular to a content retrieval method, a method for constructing a retrieval database, a content retrieval device, a construction device for a retrieval database, electronic equipment, Non-transitory computer-readable storage media and computer program products storing computer instructions. Background technique [0002] In related technologies, when a user performs a search, it usually needs to turn multiple pages to obtain the knowledge he is really interested in, and the search cost is relatively high. In addition, the correlation between the content of the search results and the search terms is low, and some cheating webpages even provide false index words to mislead the recall and affect user experience. Contents of the...
