Embodiment Construction

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] Such as figure 1 As shown, it is a flow chart of the first embodiment of the present invention, which provides a method for query expansion using a search engine, specifically including:

[0020] Step S101, the user query is distributed to each search engine in the search engine cluster, and the first N retrieval results returned by each search engine are obtained, and these retrieval results are collected into a document pool pool;

[0021] Specifically, each search engine in the search engine cluster can use different search algorithms, includ...

Abstract

The invention relates to the field of Internet search, and provides a method for performing inquiry expansion by using a search engine. The method comprises the following steps of: acquiring a search result of each search engine in a search engine cluster; evaluating each search result to acquire a weight of each search engine; and determining a core word and a modifying word which are inquired by a user, determining an expansion word according to the core word and the modifying word to form expansion inquiry for search. The invention also provides a system for performing inquiry expansion by using the search engine. By the technical scheme, a core requirement of the user is expanded according to the search results of the search engine cluster, so that the requirement of the user is relatively definite, and risk of negative feedback effect or subject drift based on partial data inquiry expansion is avoided; moreover, multi-angle and multi-side searching results can be supplied to the user, and the user requirement can be greatly met and can be even guided; and therefore, the user experience of the search engine is greatly improved.

Description

technical field [0001] The invention relates to the technical field of Internet search, in particular to a method and system for query expansion by using a search engine. Background technique [0002] With the rapid development of computer technology and Internet technology, the data and information on the Internet have increased dramatically. Faced with massive digital information, people usually need to use search engines to obtain the information they want. For search engines, how to better understand the needs of users and how to extract information that users are interested in from massive data and return them to users has become a primary issue. [0003] For a general search engine, there is usually only one input box to accept the user's query. This makes it challenging to understand the core needs of users' queries as well as the details of specific needs. If the user's query statement is too short, it is difficult to find out all the details of the user's needs, ...
