Method and device for providing retrieval associated word

Abstract

The invention relates to a retrieval technology, and discloses a method and a device for providing a retrieval associated word, which are used for improving the accuracy of the retrieval associated word and the retrieval efficiency of a search engine; and the method is characterized by comprising the steps that: aiming at the retrieval keyword which is input by a user, a fuzzy matching mode is not adopted to obtain the retrieval associated word, target word segmentations are extracted on the basis of the text data which is contained in a webpage of the retrieval keyword, then the association degrees between each target word segmentation and the retrieval keyword are calculated, the target word segmentations which have the association degrees reaching a set threshold value are presented as the retrieval associated words, so a logical association relation with the retrieval keyword and other retrieval associated words which have or do not have the fuzzy matching relation can be obtained according the information content which is contained in the webpage of the retrieval keyword, accordingly, the information accuracy of the retrieval associated words is improved, the omission of part retrieval associated words is avoided, and furthermore, the retrieval efficiency of the search engine is effectively improved.

Description

technical field [0001] The invention relates to retrieval technology, in particular to a method and device for providing retrieval associated words. Background technique [0002] With the rapid increase of the amount of information and data on the Internet, in order to serve users better, it is necessary for search engines to adopt auxiliary means to improve search efficiency, and intelligent recommendation of search related words is one of the various auxiliary means. refer to figure 1 As shown, the so-called intelligent recommendation of search related words means that when a user enters a search keyword, for example, ginseng, a series of words that may be associated with the search keyword entered by the user will be displayed on the search page, which is called search Associated words, such as figure 1 As shown, ginseng fruit, ginseng invigorating spleen pills, ginseng doll..., click on these search related words, and the user can conduct further searches. [0003] At...

AI Technical Summary

Problems solved by technology

[0011] However, when the existing search engines provide search related words, they do not take into account the industry characteristics of the search related words. The recommended search related words are generally common keyword sequences, and the existing search engines usually use fuzzy matching to recommend search related words. , in this way, many search related words that do not have a fuzzy matching relationship with the search keywords but have a certain logical relationship will not be recommended

For example, when the search keyword entered by the user is "ginseng", the search related words "saponin" and "astragalus" which have a certain logical relationship with "ginseng" will not be recommended, thus affecting the search to a certain extent. The accuracy of associated words, thus reducing the retrieval efficiency of search engines
