Abstract

The invention provides a method and system for identifying a demand classification corresponding to searching. The method comprises the following steps that (a) word segmentation operation is conducted on input searching words, and at least one key word is obtained; (b) a model vector of the key word in a neural network language model is extracted; (c) the correlation fractions of the searching words in multiple demand classifications are calculated according to the model vector; (d) a vector to be identified is judged by using a classifier, and the demand classification corresponding to the searching words is obtained. According to the method and system for identifying the demand classification corresponding to searching, the searching key word input by a user can be identified so that a specific demand classification information category can be matched for the user, targeted classification information searching can be conducted under the demand category, and thus the system can accurately and efficiently identify searching demands.

Description

technical field [0001] The invention relates to a search technology for a classified information website, in particular to a method and system for identifying a demand classification corresponding to a classified information search. Background technique [0002] Search engine (search engine) refers to the use of specific computer programs to collect information on the Internet according to certain strategies, organize and process the information, and display the processed information to users, which is to provide users with retrieval services. system. Search engines include full-text index, directory index, meta search engine, vertical search engine, aggregate search engine, portal search engine and free link list, etc. With the rapid development and maturity of the Internet on a global scale, the information resources on the network are constantly enriched, and the amount of information data is also expanding rapidly. Obtaining information through search engines has become...
