In this study, we describe the linguistic characteristics of online review texts on Movie in order to develop an efficient opinion evaluation system of online documents: we analyze especially lexico-semantic features such as positive keywords or negative keywords, syntactic properties such as negative constructions, distribution of collocated nouns, conditional constructions, comparative constructions, and some frozen expressions conveying a positive or negative polarity. We underline the current approach to opinion mining using mostly statistical methods should be reinforced with a more serious linguistic description of review texts. We introduce a finite grammar named LGG(Local-Grammar Graph) which allows to formalize linguistic description into finite-state graph equivalent to FST(finite-state transducer): this task can be performed in an efficient way by the support of the UNITEX developed for this purpose. We present a result of the application of the LGG-MOVIE which represents a part of the linguistic patterns we discussed in this paper on a new sub-set of review texts on Movie.
