摘要：AbstractWhile it is already possible to construct a large-scale English corpus easily and inexpensively using web documents, such documents have problems of reliability with respect to their English quality. Thus, we have developed a system that automatically gathers English technical papers from the web, sorts them into those written by native speakers and those written by non-native speakers, and then uses them to construct a native speaker and non-native speaker corpus. We discuss a method of using the corpus for providing alternative candidates for appropriate adjectives against unnatural English adjective-noun co-occurrence constructions . The appropriateness of adjectivea’ is evaluated based on the similarity of the occurring environments betweenaanda’.
