Abstract

The invention relates to a keyword expanding method and device based on associated application. The method comprises the steps that first stage keywords covered by to-be-expanded APPs are obtained, and associated second stage APPs are obtained according to the APPs searched by all first stage keywords; second stage keywords covered by all the second stage APPs are obtained, and third APPs associated with the to-be-expanded APPs are obtained according to the APPs searched by all second stage keywords; a candidate keyword set is obtained according to the keywords covered by all the third APPs; the similarity of all obtained third stage APPs relative to the second stage APPs is determined, and the proportion of the keywords in the candidate keyword set is obtained; the similarity scores of all the keywords in the candidate keyword set are calculated; the candidate keyword set is screened according to the similarity scores so as to obtain the associated keywords of the to-be-expanded APPs.The APP associated keywords can be expanded automatically, the yield can be realized, and at the same time, the expanding quality can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of data analysis, in particular to a keyword expansion method and device based on associated applications. Background technique [0002] With the rapid development of smart terminals, it has driven the development of the mobile Internet software industry. More and more users download various APPs (applications, also referred to as applications) from the application library platform (ie application store) in smart terminals. According to Wikipedia data, 65% of users search and download the required applications through the application store. Therefore, in order to improve the search quality of their own APP in the application store, APP developers need to do a good job in the optimization of the application store. One of its key tasks is to do a good job in keyword analysis of APP to optimize its own APP. [0003] At present, based on the specific industry knowledge background of the smart terminal applicat...
