Sentiment Detection Using Lexically-Based Classifiers

Abstract

This paper addresses the problem of supervised sentiment detection using classifiers which are derived from word features. We argue that, while the literature has suggested the use of lexical features is inappropriate for sentiment detection, a careful and thorough evaluation reveals a less clear–cut state of affairs. We present results from five classifiers using word based–features on three tasks, and show that the variation between classifiers can often be as great as has been reported between different feature sets with a fixed classifier. We are thus led to conclude that classifier choice plays at least as important a role as feature choice, and that in many cases word–based classifiers perform well on the sentiment detection task.
