Abstract

The invention relates to a clustering method for keywords and a device for conducting the clustering method. The method includes the steps that a keyword set is established, wherein the keyword set comprises the multiple first keywords and the multiple second keywords and each second keyword is related to at least one first keyword; similarity values between each first keyword and the second keywords related to the first keyword are calculated respectively and multiple first clustering clusters are established according to the similarity values; one first clustering cluster is selected randomly to serve as an initial clustering cluster, so that the second clustering processing step is conducted, wherein the second clustering processing step includes the processes that the other first clustering clusters are searched for the first clustering clusters having an equivalent clustering relation with the initial clustering cluster, the found first clustering clusters are combined with the initial clustering cluster, and therefore a second clustering cluster is formed. According to the clustering method for the keywords, more potential relations can be dug and searching efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a keyword clustering method and device in network search technology. Background technique [0002] In network search technology, users generally search for corresponding results through a search string (query, a search keyword submitted by a user in a search engine). The sponsored search advertising system is an advertising search system based on a search engine. The engine platform uses the user's search string to match the keywords (also called bidterm) submitted by the advertiser or agency. Push advertisements to target users. [0003] In the bidding search advertisement system, in order to improve the search efficiency of advertisements, a method of clustering keywords provided by advertisers in the bidding search advertisement system is proposed. [0004] At present, the most commonly used clustering method is as follows: for the keywords provided by an advertise...
