Problems solved by technology

[0004] However, the bidding terms purchased by the application developer may not match the application itself, so that when the search engine of the application distribution platform searches based on the search term entered by the user, it may return an application that is actually not very relevant to the search term The information of the program causes the user to perform more operations in order to find the application program he needs, such as turning the page, which affects the efficiency of obtaining the application program he needs

Embodiment Construction

[0049]In view of the above problems, the present invention is proposed to provide a method and device for searching application programs using keyword databases under secondary categories to overcome the above problems or at least partially solve the above problems.

[0050] In order to better understand the above-mentioned technical solution, the above-mentioned technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0051] First of all, the term "and / or" that appears in this article is just an association relationship that describes associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: there is A alone, and A exists at the same time and B, there are three cases of B alone. In addition, the character " / " in this article generally indicates that the contextual objects are an "or" relationship.

Abstract

The invention discloses a method and device for searching for applications through a keyword bank under a second-level category. According to the method, a classifier is adopted to divide all the applications into the second-level category under a corresponding first-level category by use of description information of all the applications under the first-level category; according to the click relation between search terms in historical search records and all the applications and the second-level category which all the applications belong to, a second-level category corresponding to the search terms is calculated; a keyword bank under the second-level category corresponding to all the search terms is generated; and when a search keyword input by a user is received, if the search keyword is successfully matched with the keyword banks under all the second-level categories, the applications under the second-level category corresponding to the search keyword are acquired. Through the method and the device for searching for the applications through the keyword bank of the applications, the problem that an application developer needs to select an index keyword of the applications through complicated operation and the problem that the probability of occurrence of the applications in a search result in low relevancy to the search term input by the user is high due to the fact that the selected index keyword is improper are solved.

Description

technical field [0001] The invention relates to the field of search technology, in particular to a method and device for searching application programs using a keyword library under a secondary category. Background technique [0002] With the development of smart mobile terminals, more and more users download and use various APPs (applications) in smart mobile terminals. Based on this situation, the application program distribution platform came into being. Users can access the application program distribution platform through smart mobile terminals, such as accessing the application program distribution platform through the application program distribution application installed in the smart mobile terminal, so that they can download from the platform. various applications. Among them, the application program distribution application is such as various mobile phone assistants. [0003] In the application distribution platform, in order to provide application owners with pr...
