Structural Correspondence Learning for Cross Domain Sentiment Analysis in Brazilian Portuguese
Over the years, many approaches to the cross domain task in Sentiment Analysis have been proposed. The vast majority of such approaches concerns corpora in English language. Following a different methodology, this paper proposes three novel product review datasets written in Brazilian Portuguese. These datasets are freely available and they cannot only be used as benchmark datasets by other researchers, but also to perform domain adaptation comparative assessments. In addition, the entire creation process for the proposed datasets is described. Another contribution resides in the first experimental evaluation of the state of the art algorithm Structural Correspondence Learning (SCL) on cross domain sentiment analysis (domain adaption) Furthermore, two other variants of the original SCL algorithm are evaluated on the proposed datasets and their performance are compared against each other.
