Abstract: Now a days with increased use of social media, user reviews on any product plays a significant role. The existing opinion mining techniques operate only on single review corpus; it doesn’t consider distribution of opinion features across different corpora. A new technique is proposed to extract opinion features from online reviews across two corpora, one a given review corpus and other is contrasting corpus. This discrepancy is evaluated using domain relevance. The first step is to find candidate opinion features in domain review corpus using syntactic dependence rules. This evaluate intrinsic domain relevance scores for each candidate on domain-dependent corpora and extrinsic domain relevance score on domain-independent corpora. A candidate features which are less generic and more domain specific are the final opinion features. This interval thresholding is called as the intrinsic and extrinsic domain relevance.
