Abstractsmall Previous works on question classification are based on complex natural language processing techniques: named entity extractors, parsers, chunkers, etc. While these approaches have proven to be effective they have the disadvantage of being targeted to a particular language. We present here a simple approach that exploits lexical features and Internet to train a classifier, in particular a Support Vector Machine. The main feature of this method is that it can be applied to different languages without requiring major adaptation changes. Experimental results of this method on English, Italian and Spanish show that this approach can be a practical tool for question answering systems reaching classification accuracy as high as 88.92%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
