Evaluating Lexical Similarity to build Sentiment Similarity
Résumé
In this article, we propose to evaluate the lexical similarity information provided by word representations against several opinion resources
using traditional Information Retrieval tools. Word representation have been used to build and to extend opinion resources such as
lexicon, and ontology and their performance have been evaluated on sentiment analysis tasks. We question this method by measuring the
correlation between the sentiment proximity provided by opinion resources and the semantic similarity provided by word representations
using different correlation coefficients. We also compare the neighbors found in word representations and list of similar opinion words.
Our results show that the proximity of words in state-of-the-art word representations is not very effective to build sentiment similarity.
