In the late years sentiment analysis and its applications have reached growing popularity. Concerning this field of research, in the very late years machine learning and word representation learning derived from distributional semantics field (i.e. word embeddings) have proven to be very successful in performing sentiment analysis tasks. In this paper we describe a set of experiments, with the aim of evaluating the impact of word embedding-based features in sentiment analysis tasks.Recentemente la Sentiment Analysis e le sue applicazioni hanno acquisito sempre maggiore popolarità. In tale ambito di ricerca, negli ultimi anni il machine learning e i metodi di rappresentazione delle parole che derivano dalla semantica distribuzionale (nello s...
