Lemon and tea are not similar: Measuring word-to-word similarity by combining different methods

Abstract

Substantial amount of work has been done on measuring word-to-word relatedness which is also commonly referred as similarity. Though relatedness and similarity are closely related, they are not the same as illustrated by the words lemon and tea which are related but not similar. The relatedness takes into account a broader ranLemge of relations while similarity only considers subsumption relations to assess how two objects are similar. We present in this paper a method for measuring the semantic similarity of words as a combination of various techniques including knowledge-based and corpus-based methods that capture different aspects of similarity. Our corpus based method exploits state-of-the-art word representations. We performed experiments with a recently published significantly large dataset called Simlex-999 and achieved a significantly better correlation (ρ = 0.642, P < 0.001) with human judgment compared to the individual performance.
