Abstract

This paper presents first steps of an ongoing work aiming at the constitution of lexicons for opinion mining. Our work is corpus-oriented, the corpus being of informative nature (related to avionic manufacturers) rather than opinion-oriented (as in current works dealing with social networks). We especially investigate the question of interrelation between factual information and evaluative stance. Another aspect concerns the intensity of expressed opinions. Lexicons for adjectives and adverbs have been built, based on the given corpus, of which we present the principles and modus operandi.
