Problems solved by technology

Even in the field of relatively easy web page search, synonym mining algorithms still have problems such as poor results and low accuracy of synonyms
Therefore, there is still no good way to bridge the semantic gap between user application search and app application

Embodiment Construction

[0100] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0101] In the following, app represents an application, query represents a search term, tag represents a tag, and TagNet represents a tag database.

[0102] The invention is to construct the tag knowledge base TagNet, which is the key to realize the function search technology. Similar to WordNet, TagNet builds a knowledge system that organizes tag associations, maps user intentions and app functions into the same tag system, and so...

Abstract

The invention discloses a method and device for constructing a tag knowledge base, an application search method and a server. The method includes: obtaining a plurality of tag lists related to application search words; obtaining a plurality of application tag lists; according to the search words The label list of the application, the label list of the application, and the preset strategy are used to build a label knowledge base for matching the search term and the application when the application is searched; wherein, each label list includes one or more labels. The tag knowledge base constructed by the company solves the technical problem of calculating the correlation between search words and applications, can search for applications related to query intentions, optimizes the layout and display of search results, and realizes the effect of search plus recommendation. The invention maps user intentions and applications into the same semantic space, solves the problem of semantic matching, and effectively implements functional search technology.

Description

technical field [0001] The invention relates to the field of data mining, in particular to a method and device for constructing a label knowledge base, an application search method and a server. Background technique [0002] When the application search engine is a mobile terminal software application search engine service, it can provide app search and download on mobile phones, such as 360 Mobile Assistant, Tencent App Store, Google Play, Appastore, etc. With the development of the mobile Internet, the number of mobile app applications continues to increase, making it more difficult for users to search for applications that meet their intentions among the massive applications. [0003] In the traditional application retrieval technology based on keyword matching, when users express their search intentions with search words with similar semantics, they often fail to obtain the intended app due to keyword mismatch. The existing general solution is to mine synonyms, hoping to...
