Abstract

The embodiment of the invention discloses a determining method and device of a search term weight value. The method comprises the steps that search log information is classified according to a set rule; and according to the difference of a search term in at least two kinds of search log information, the weight value of the search term is determined. The device comprises a log information processing module and a weight value computing module. The log information processing module is used for carrying out classifying on search log information according to the set rule. The weight value computing module determines the weight value of the search term according to the difference of the search term in the at least two kinds of search log information. The technical problem that an existing search term weight value is determined by the number of documents containing the search term in a network, and large different with the importance degree of the search term in a search formula exists is solved, an existing search word weight value determining technology is optimized, so that the search word weight value obtained by computing is closely related to user practical search operation, the accuracy of the search term weight value is improved, and the searching effect of a search engine is improved.

Description

technical field [0001] The embodiments of the present invention relate to data processing technologies, and in particular to a method and device for determining weight values ​​of query words. Background technique [0002] With the continuous development of Internet technology and the continuous penetration of Internet applications into people's work, study and life, more and more people obtain information through the Internet. Typically, a user inputs a query formula (Query) through a search engine, and the search engine returns search results matching the input query formula to the user by adopting a certain search sorting method. Among them, when the search engine processes the query formula input by the user, it will give different weights to the query terms (Term) included in the query formula to reflect the importance of different query terms in the query formula (also called Term importance), The search engine sorts the search results by jointly using the importance ...
