摘要：This paper presents experiments performed on lexical knowledge acquisition in the formof verbal argumental information. The system obtains the data from raw corpora after theapplication of a partial parser and statistical filters. We used two different statistical filters to acquire the argumental information: Mutual Information, and Fisher's Exact test. Due tothe characteristics of agglutinative languages like Basque, the usual classification ofarguments in terms of their syntactic category (such as NP or PP) is not suitable. For thatreason, the arguments will be classified in 48 different kinds of case markers, which makesthe system fine grained if compared to equivalent systems developed for other languages. This work addresses the problem of learning subcategorization frames by distinguishingarguments from adjuncts, being the last ones the most significant source of noise insubcategorization frame acquisition.
