The focus is put on the ‘affect’ and ‘orientation’ subcategories of such theory.
This research is a first approach to an automated analysis of sentiment in large corpora, reason why the corpus consisted of 800 reviews taken from a website; 400 negative reviews and 400 positive reviews. This had the objective of finding out whether there were differences in the way each polarity or orientation was conveyed.
The results show a relation with the Appraisal Theory’s categories mentioned, although there is no difference in the way negative and positive sentiments are expressed. In terms of lexical items, however, there is a difference in the use of modal verbs, which are found in a slightly larger quantity in negative reviews.
The evaluative structures proposed by Hunston and Sinclair (2000) served as a database from which to start, however, they were not found as pervasively in the texts as expected. On the contrary, a whole set of new structures seems to arise from this research.
Future applications of the findings of this research include the creation of computer-based platforms that may detect evaluation automatically, thus helping the identification of the needs of customers, not only of hotels, but of different kinds of services.
