Abstract

The invention provides a method and device for mining synonyms. The method comprises the following steps of: searching a query and a webpage title which is clicked or browsed in a searching result corresponding to the query from a searching log, or allowing the clicked or browsed webpage title to correspond with different queries, and acquiring a candidate resource of a synonym formed by phrase pairs; and extracting a synonym from each phrase pair of the candidate resource, wherein the extracted synonym pair has the same context from the phrase pairs. According to the method and device for mining synonyms, the efficiency and accuracy of mining synonyms can be improved, and the mined synonyms can be in more accordance with the language characteristics of a search engine.

Description

【Technical field】 [0001] The invention relates to the field of computer technology, in particular to a method and device for mining synonyms. 【Background technique】 [0002] When a user is using a search engine to search, in order to recall webpages that match the synonyms of the query entered by the user in the search results, a synonym-based search request (query) extension will be used, that is, when using query While searching, the synonyms of query are also used for searching. In order to apply this technology in search engines, the mining of synonyms is a very important basic work. [0003] Existing synonym mining methods perform synonym mining by calculating the correlation probability between words in the corpus, but this method needs to calculate pairs of words in the corpus, and the efficiency is very low. 【Content of invention】 [0004] In view of this, the present invention provides a method and device for mining synonyms, so as to improve the efficiency of m...
