TopThe problem of automatic determination of the semantic orientation of words and documents by their polarities is not new in the community of linguistic researchers. A pioneered approach for clustering of adjectives by their polarities has been described in (Hatzivassiloglou & McKeown, 1997), which uses contrary and cooperating conjuncts for this task. Various machine learning methods like Support Vector Machine (SVM) (Joachims, 1998), and Naïve Bayesian (NB) have gained interest for performing automatic text classification in the late 1990s (Agarwal & Mittal, 2014) for organizing the e-documents in online digital libraries. Till that time, the targeted e-documents include stories, movies, books, technical papers, etc. These e-documents are usually very consistent on grammar and spelling. However, with the boom in e-commerce sites an extreme affection of linguistic researchers has been observed in classifying the online reviews of products on the basis of writer’s opinion on a product into positive and negative polarities (Ding et al., 2008; Turney, 2002; Liu & Cheng, 2005; Srivastava et al., 2010; Baumgarten et al., 2013), and a new terminology i.e. “Opinion–Mining” (OM) has been coined in the horizon of Natural language processing (NLP) and text mining for collective representation of the works of similar kind (Ohmura, et al., 2014; Hariharan & Ramkumar, 2011). Up to this era of time, most of the tasks of sentiment analysis favor some hybrid approaches using both: the time-consuming classical methods of NLP (e.g. Rule-based) and Statistical and Machine Learning (ML) approaches.
