Problems solved by technology

[0005] However, there are some search terms that are not provided by the advertiser, but they are essentially related to the advertisements corresponding to the search terms provided by the advertiser, and the aforementioned clustering method is to cluster the search terms provided by the advertiser only literally , does not take into account these other search terms that are semantically related to the search terms provided by the advertiser and have not yet been provided by the advertiser, which reduces the accuracy of the search term clustering

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] When the present invention clusters search terms, it does not only cluster the search terms provided by users such as advertisers as in the prior art, but clusters the search terms provided by users according to the textual features and / or semantic features of the search terms. The search term, and the search term clustering related to the search term, in order to increase the accuracy of the search term clustering, the method provided by the present invention will be described below.

[0027] see figure 1 , figure 1 The basic flowchart provided for the embodiment of the present invention. Such as figure 1 As shown, the process may include the following steps:

[0028] In step 101, a set of candidate search terms is established, and the...

Abstract

The invention provides an index word clustering method and device. The index word clustering method comprises the following steps of: A, establishing a candidate index word set, wherein the candidate index word set comprises index words provided by a user and index words relevant to the index words provided by the user; and B, clustering the index words in the candidate index word set according to text characteristics and / or semantics characteristics of the index words. With the adoption of the index word clustering method and device provided by the invention, the accuracy of clustering the index words can be improved.

Description

technical field [0001] The invention relates to network search technology, in particular to a method and device for clustering search words. Background technique [0002] In network search technology, users search for corresponding results through search terms. When applied to a bidding advertising system, the search term can be used to identify the advertisement provided by the advertiser when implemented, and can also be called a purchase term. The purpose is to facilitate users to search for corresponding advertisements through the search term. [0003] In the bidding advertisement system, in order to improve the efficiency of advertisement search, it is proposed to cluster the search terms provided by the advertisers in the bidding advertisement system. Among them, clustering the search terms can be abstracted as a process of clustering a set of short text strings. [0004] At present, the most commonly used clustering method is: for the search terms provided by an adv...
