Document index generation method and device based on word segment weights

Abstract

The embodiment of the invention provides a document index generation method and device based on word segment weights. The method comprises following steps of setting anchor text weights corresponding to documents; configuring feature weights for word segments contained in the anchor texts according to the anchor text weights; determining the word segment weights of the word segments relative to the documents based on the feature weights; and generating document indexes according to the word segments and the word segment weights relative to the documents. According to the embodiment of the invention, the display probability of the search result terms related to user search is improved, the search accuracy is improved, further search carried out in modes such as turning pages to search in the search results and inputting the search keywords again is reduced, the operation simplicity is improved, the resource consumption of a search engine and a local system is reduced, the bandwidth consumption is reduced, and the search efficiency is improved.

Description

technical field [0001] The invention relates to the field of search technology, in particular to a method for generating a document index based on a word segmentation weight and a device for generating a document index based on a word segmentation weight. Background technique [0002] With the rapid development of the network, the information on the network has increased dramatically. In order to find desired information among massive amounts of information, users usually use search engines to search. [0003] A search engine refers to a system that automatically collects information from the Internet, and after a certain arrangement, provides it to users for query. The information is vast and disorderly, and all the information is like small islands in the ocean. Web links are the bridges between these small islands, and search engines draw a clear information map for users. available to users at any time. [0004] Search engines usually build document indexes in advance...

AI Technical Summary

Problems solved by technology

[0005] The document index in the search engine is generally a database index table, and the results obtained by searching based on the database index table are often not what the user needs, and the accuracy rate is low

When users do not find the desired information, they usually search by flipping pages in the search results and re-entering search keywords. The operation is cumbersome, the resource consumption of the search engine and the local system is large, the bandwidth consumption is large, and the search efficiency is low.
