Embodiment Construction

[0047] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0048] Please refer to figure 1 , image 3 , a method for realizing information retrieval in a network in Embodiment 1 of the present application, comprising the following steps:

[0049] Step 101, segment the Query for information retrieval to obtain one or more word segments.

[0050] In the specific implementation process, Query is a query word input by the user in the search engine, and is used to retrieve information, such as: "iphone4 white mobile phone". When word segmentation is carried out to described " iphone4 white mobile phone ", described " iphone4 white mobile phone " can be carried out word segmentation automatically by search engine, and can obtain one or more word seg...

Abstract

The invention discloses a method and a system for achieving information retrieval in a network, wherein the method for achieving the information retrieval in the network is used for improving the accuracy rate and the coverage rate of property prediction for a Query. The method comprises the following steps that word segmentation for the Query to be in information retrieval is carried out to obtain one or more segmentations; through segmentation matching, one or more properties matched with each segmentation are obtained; aiming at each segmentation and a property corresponding to each segmentation, dependency fractions of the segmentations and the properties are calculated; the properties with the dependency fractions larger than a preset threshold value are predicted to be properties of the Query; and according to the predicted properties, the information retrieval is carried out.

Description

technical field [0001] The present application relates to the technical field of Internet search, in particular to a method and system for realizing information retrieval in the network. Background technique [0002] With the continuous development of computer network technology, users can retrieve more and more information in the computer network. In recent years, with the increasing amount of data in the computer network, users' requirements for accurately and quickly retrieving information that meets their needs in the network are also increasing. [0003] When a user actually uses a search technology such as a search engine, for example, to retrieve product information, for the search term (Query) input by the user in the search box provided by the search engine, the search engine may not be able to predict the product information corresponding to the Query, And it is impossible to describe the attributes of these commodity information accurately and without redundancy....
