Second query term determined to be related to first query term based on natural searching results

Abstract

The invention provides a method and device for determining a second query term related to a first query term based on natural searching results. The method comprises the first step of obtaining the natural searching results corresponding to the first query term inputted by a user and the natural searching results corresponding to one or more candidate query terms respectively, the second step of determining the relevancy between the first query term and the one or more candidate query terms respectively according to check processing of the natural searching results corresponding to the first query term and the one or more candidate query terms, and the third step of determining the second query term related to the first query term from the one or more candidate query terms according to the relevancy. Compared with the prior art, the relevancy between the second query term and the first query term inputted by the user is guaranteed, furthermore, the relevancy between the displaying results corresponding to the second query term and the first query term is improved, and therefore the usage experience of the searching user is improved.

Description

technical field [0001] The present invention relates to the field of search technology, in particular to a technology for determining a second query word associated with a first query word based on natural search results. Background technique [0002] During the user's search process, in addition to providing the user with natural search results corresponding to the query words entered by the user, the search engine will also provide the user with corresponding display results, such as triggering display according to the words corresponding to the query words.
