Daniela Moctezuma et al., « On the performance of B4MSA on SENTIPOLC’16 », Accademia University Press, ID : 10.4000/books.aaccademia.2017
This document describes the participation of the INGEOTEC team in SENTIPOLC 2016 contest. In this participation two approaches are presented, B4MSA and B4MSA + EvoDAG, tested in Task 1: Subjectivity classification and Task 2: Polarity classification. In case of polarity classification, one constrained and unconstrained runs were conducted. In subjectivity classification only a constrained run was done. In our methodology we explored a set of techniques as lemmatization, stemming, entity removal, character-based q-grams, word-based n-grams, among others, to prepare different text representations, in this case, applied to the Italian language. The results show the official competition measures and other well-known performance measures such as macro and micro F1 scores.
