Little words can make a big difference for text classification

Ellen Riloff
1995 Proceedings of the 18th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '95  
However, we have found that recognizing singular and plural nouns, vexb forms, negation, and prepositions can produce dramatically different text classification results.  ...  We present results from text classification experiments that compare relevancy signatures, which use local linguistic context, with corresponding indexing terms that do not.  ...  However, for some classification tasks, classifying texts on the basis of a single linguistic expression can be effective.  ...
