Method for improving searching engine based on keyword index using phrase index technique

Abstract

The invention relates to a method for improving a search engine which is based on keyword index by using phrase indexing technology; after receiving the user query sent by users, the invention first preprocesses the query, then sends the query to a query analysis module, an interface of the search engine and a web page data processing module respectively, and the generation of phrase can be fulfilled by the query analysis module respectively; the interface of the search engine and the web page data processing module take web page data from a traditional search engine, carry out data processing of web text so as to generate inverted lists; then the phrase generated by the query analysis module is subject to retrieval and matching in the inverted lists, which are obtained from the interface of the search engine and the web page data processing module, through a retrieval ordering module, meanwhile, based on an original ordering given by the search engine, the invention can carry out regulation on the original ordering according to the matching degree of the phrase; finally, the final result is returned to a client and the automatic summarization of the web page can be given simultaneously. The invention has higher sequencing scientificity.
