Abstract

The invention discloses a recognition method and device for application search intentions and an application search method and server. The method includes the steps that search terms in query sessions are acquired from a query session log of an application search engine; label systems of the search terms are mined according to the search terms in the query sessions and preset strategies; the application search intentions corresponding to the search terms are recognized according to the label systems of the search terms. In the scheme, by proposing the label method of the recognition method for the user intentions corresponding to the app label systems, the fine-grained user query intentions are flexibly expressed. The label systems of the user intentions are constructed based on the unsupervised machine learning technology, a traditional user intention classification method is abandoned, an automatic user intention mining process is achieved, and a high-accuracy and high-recall-rate user intention label list can be generated; the user intentions and apps are mapped into the same label system, and thus a user can rapidly and accurately acquire apps meeting intentions when searching for apps.

Description

technical field [0001] The present invention relates to the field of data mining, in particular to an application search intent identification method, device, application search method and server. Background technique [0002] App search engine is a mobile software application search engine service that provides app search and download on mobile phones, such as 360 Mobile Assistant, Tencent App Store, Google Play, Appstore, etc. Application search engines are mobile search services installed on mobile phones, such as 360 mobile assistant app applications. Due to the limitations of objective conditions such as the small display plane of search results, the best user experience can only be obtained by providing accurate search results. One of the important differences in PC-side web search. The number of mobile app applications is huge, with millions of app applications. The application search engine needs to understand the user's query intention in order to accurately displa...
