A search method and system

Abstract

The embodiments of the present application provide a retrieval method and system to solve the problems of high matching, low precision and single retrieval results in existing retrieval methods. The method includes: obtaining the user's historical query data, extracting the product attributes in the title and the text; for each product attribute obtained offline and a related product attribute database of the product attributes, calculating the correlation between them and the product attributes contained in the historical query data. Based on the correlation degree, the product attributes obtained in the offline process and their corresponding related product attribute lists are screened and retrieved as query expansion words. Since the information in the final web page of the user's point search effectively reflects the user's needs, this information is subsequently used to search for extended words, which improves the search accuracy and expands the recall of the search, effectively solving the search problem. The problem of no results or few effective search results greatly improves the user's search experience.

Description

technical field [0001] This application relates to the field of Internet information retrieval, in particular to a retrieval method and system. Background technique [0002] Information retrieval is the basis of content-driven applications, and the quality of search results directly affects whether users can quickly and timely obtain the information they need. At present, vertical search engines for specific fields meet the needs of users to obtain specific information to a certain extent. However, the existing full-text search engines based on text matching use search methods to filter web pages according to the degree of matching, resulting in too many search results. Depending on the selection of search terms, problems of high matching, low precision, and single search results often occur. Contents of the invention [0003] The embodiment of the present application provides a retrieval method and system to solve the problem that the retrieval method cannot perform retr...

Problems solved by technology

[0003] The embodiment of the present application provides a retrieval method and system to solve the problem that the retrieval method cannot perform retrieval from a semantic point of view, and the search results rely too much on the selection of search terms, which often leads to high matching, low precision, and single retrieval results.
