A simple algorithm for the lexical classification of comparable adjectives

Abstract

Lexical classification is one of the most widely investigated fields in (computational) linguistic and Natural language Processing. Adjectives play a significant role both in classification tasks and in applications as sentiment analysis. In this paper we propose MORE (coMparable fORm dEtector), a simple algorithm for lexical classification of comparable adjectives. The algorithm is ecient in time. The method is a specific unsupervised learning technique. We verify results against a reference standard built from 80 manually annotated lists of adjective. The algorithm exhibits an accuracy of 76%
