Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0022] figure 1 A schematic diagram showing a device for determining a second query word associated with a first query word based on natural search results according to one aspect of the present invention. The device 1 includes a result obtaining means 101 , a correlation degree determining means 102 and a query word determining means 103 .
[0023] Wherein, the result obtaining means 101 respectively obtains the natural search results corresponding to the first query word input by the user, and the natural search results corresponding to one or more candidate query words. Specifically, according to the first query word input by the user and one or more candidate query words corresponding to the first query word, the result obtaining device 101 respectively obtains the natural search result corresponding to the first query word, and For the natural search r...

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. However, if the displayed result does not match or has a low matching degree with the query word input by the user, it will greatly affect the user's search experience. [0003] Therefore, how to improve the relevance of the displayed results, or in other words, the words corresponding to the displayed results, to the query words input by the user has become one of the technical problems urgently to be solved by those ...
