Abstract

The invention provides a mechanism feature vocabulary extension system for public opinion crawling. The mechanism feature vocabulary extension system comprises a data acquisition module for acquiringdata; a feature word cleaning and processing module, used for preliminarily screening feature words; and a feature word statistical analysis module, used for further screening the feature words through relevancy analysis and finally generating expansion feature words. On the other hand, the invention provides a mechanism feature vocabulary extension method for public opinion crawling. By the adoption of the scheme, useless feature words are screened out and analyzed, expanded feature words are generated, related public opinion information is comprehensively and rapidly collected, on one hand,missing inspection is effectively avoided, on the other hand, useless data added to the useless feature words is reduced, retrieval efficiency and quality are improved, and memory occupation is reduced.
