Abstract

The embodiment of the invention provides a retrieval method and system for solving the problems of high matching, low precision and single retrieval result of an existing retrieval method. The methodcomprises the steps of obtaining historical query data of a user, and extracting product attributes in a title and a text; according to commodity attribute libraries of commodity attributes and each commodity attribute obtained offline, respectively calculating the correlation with the commodity attributes included in the historical query data and the correlation with the extracted commodity attributes; based on the correlation, filtering the commodity attributes obtained in the offline process and corresponding related commodity attribute lists, and retrieving as query expansion words. Sincethe information in a final web-page where the user clicks retrieval effectively reflects needs of the user, the subsequent use of the information for the retrieval of the expansion words improves theretrieval accuracy, the retrieval recalling is expanded, the problems of no results or few retrieval valid results are effectively solved, and the retrieval experience of the user is greatly improved.

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...
