This paper mainly studies the extraction procedure of attitude-adjectives, se mantic-relations between attitude-adjectives and co-occurrence nouns and their syntactic functions. Firstly, Attitude-adjectives can be extracted from CCL corp us through three programs such as classification, determining categories and do mains. Secondly, there are three semantic relations between attitude-adjectives and co-occurrence nouns, which are inherent property-values and property-carri ers, inherent property-values and property-monitors, inherent property-values and inherent property-domains. Finally, attitude-adjectives are introduced the f our syntactic functions as predicate, attributive, adverbial and complement. In addition, constructions of noun + attitude-adjectives are described one function as adverbial.
