Abstract

The invention provides a related searching system and method. The method comprises the following steps of (a) receiving search terms, extracting key words and parameters; (b) screening candidate search terms base on the key words and parameters; (c) utilizing a neural network language model to calculate correlation between the search terms and the candidate search terms and obtaining other characteristic correlations; (d) performing weighting calculation on multiple characteristic correlations to obtain related search term results. The related searching system comprises a receiving module for receiving the search terms, a key word extracting module for extracting the key words and parameters, a search term database for storing the candidate search terms, a screening module for searching the candidate search terms under the screen conditions of the key words and parameters, a correlation calculating module for calculating the multiple characteristic correlations and a fusion module for performing the weighting calculation on multiple characteristic correlation fractions to obtain the related search term results. By means of the related searching system and method, efficient and accurate related searching can be achieved through a simple structure.

Description

technical field [0001] The invention relates to the technical field of search engines, in particular to a related search system and method. Background technique [0002] With the development of the Internet, various services can be provided to clients through the Internet network side. One of them is the search service, that is, a search engine is set up on the network side. When the search engine on the network side receives the search request sent by the client, it retrieves the keywords stored in the candidate database on the Internet network side that match the keyword carried in the search request. All literal indexes, provided to clients. In order to improve the search experience of users using the client, a related search technology is proposed, that is, after the search engine on the network side receives a search request, it not only retrieves all the literal indexes in the candidate database on the Internet network side that match the keywords carried by the searc...
