Evaluating cross domain sentiment analysis using supervised machine learning techniques

Abstract

Sentiment Analysis is the process of computationally identifying and categorizing opinion expressed in a piece of text, especially in order to determine whether the writer's attitude towards a particular topic is negative, positive or neutral. Many researchers have proposed novel methods for sentiment classification especially using supervised machine learning (ML) techniques. However, there is still limited research with successful results in Cross-Domain Sentiment Analysis. Therefore, previous experiments were replicated by using different ML techniques with several enhancements in order to better understand the sentiment classification process and to compare results with cross-domain analysis. Limitations of the proposed approach are discussed and a new automated model is suggested for future work.
