AFFIMO: Toward an open-source system to detect AFFinities and eMOtions in user’s sentences

Abstract

In this paper, we present AFFIMO (AFFInities and eMO- tions), a first attempt to develop an open-source system to detect user’s emotions and affinities from sentences in natural language. AFFIMO integrates a lexical analysis based on SentiWordNet dictionary, a syntactic analysis to consider intensifiers and negation, and a semantic analy- sis to compute the valence of a sentence (positive or nega- tive) in the light of the user’s detected affinities. AFFIMO has been implemented and tested on different sentences.
