Dictionary-Based Voting Text Categorization in a Chemistry-Focused Search Engine

A chemistry-focused search engine, named ChemEngine, is developed to help chemists to get chemical information more conveniently and precisely on Internet. Text Categorization is used in ChemEngine to facilitate users’ search. The semantic similarity and noisy data in chemical web pages make traditional classifier perform poorly on them. To classify chemical web pages more accurately, a new text categorization approach based on dictionary and voting is proposed and integrated into the ChemEngine.
