Hernández Farías Delia Irazú et al., « Towards an Italian Lexicon for Polarity Classification (polarITA): a Comparative Analysis of Lexical Resources for Sentiment Analysis », Accademia University Press, ID : 10.4000/books.aaccademia.2417
The paper describes a preliminary study for the development of a novel lexicon for Italian sentiment analysis, i.e. where words are associated with polarity values. Given the influence of sentiment lexica on the performance of sentiment analysis systems, a methodology based on the detection and classification of errors in existing lexical resources is proposed and an extrinsic evaluation of the impact of such errors is applied. The final aim is to build a novel resource from the filtering applied to the existing lexical resources, which can integrate them with missing lexical entries and more reliable associations of polarity with entries.
