Embodiment Construction

[0072] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0073] One of the core concepts of the embodiments of the present invention is to identify whether the search request does not have obvious search intent according to the search request sent by the user. , on the basis of the existing inverted index search method, supplement at least one other search method to obtain search result information, so that the search result information can be more abundant, so that it can be more easily obtained when the user does not have obvious search intentions Get the search result information that the user is interested in. At the same time, in the face of various sources of search result information, simply providing search result information to users based on the original arrangement of search result information for each search method may make it difficu...

Abstract

The embodiment of the invention provides an information search method and device. The method comprises the following steps: responding to a search request sent by a user, and recognizing whether the search request is a generalization search request or not; the generalization search request is a search request with a fuzzy search intention; if the search request is a generalization search request, adopting a reverse index search mode and at least one search mode to obtain search result information; determining an estimated click rate of the search result information according to the relevancy between the search result information and the generalization search request and / or the relevancy between the search result information and the user; based on the estimated click rate, determining an arrangement sequence of the search result information; and sending the search result information to the user by adopting the arrangement sequence. And the user can more easily find the possibly interested content in the search result information.

Description

technical field [0001] The present invention relates to the technical field of search, in particular to an information search method and an information search device. Background technique [0002] In the prior art, when a user needs to search for information on the Internet, a search condition can usually be entered in a search engine to obtain search result information returned by the search engine. Generally speaking, the search receivable can perform word segmentation, rewriting and other processing on the text contained in the search condition, so as to obtain search result information with a high degree of relevance to the search condition input by the user as much as possible. [0003] However, when a user searches for information, there may not be an obvious search purpose, and the search conditions input by the user at this time may express the general search intention of the user. For example, when the user inputs the search condition "short video", the user does n...
