Abstract

The invention discloses an efficient data screening method based on semantic analysis and relates to the field of Internet retrieval technology. According to the method, weights in a semantic space are processed from the perspective of probability in combination with a semantic analysis technology so that the weights can better reflect the semantic relation between documents and between documents and vocabularies; and by the adoption of a secondary search strategy, a search result is improved so that the search result can better meet a user requirement, and the accuracy rate and the precision rate of retrieval are increased.

Description

technical field [0001] The invention relates to the technical field of Internet retrieval, in particular to an efficient data screening method based on semantic analysis. Background technique [0002] With the explosive growth of the Internet, the World Wide Web has developed into a huge dynamic information service network that includes multiple information resources and sites all over the world. The increasing convenience of information acquisition has broadened people's horizons. At the same time, the massive amount of information has also caused many new problems. For example, the text information is seriously redundant due to the continuous reprinting of various web pages; the existing relatively limited search methods make it impossible to accurately find useful information submerged in the vast and complicated information; the flood of spam emails and spam messages, the Internet Information pollution caused by the dissemination of harmful information on the Internet. ...
