Abstract: Considering the wide spectrum of both practical and research applicability, opinion mining has attracted increased attention in recent years. This article focuses on breaking the domain-dependency issues which occur in supervised opinion mining by using an unsupervised approach. Our work devises a methodology by considering a set of grammar rules for identification of opinion bearing words. Moreover, we focus on tuning our method for the best tradeoff between precision-recall, computation complexity and number of seed words while not committing to a specific input data set. The method is general enough to perform well using just 2 seed words therefore we can state that it is an unsupervised strategy. Moreover, since the 2 seed words are class representatives (“good”, “bad”) we claim that the method is domain independent.
