摘要：This article proposes an automatic method of gradually constructing case frames. First, a large raw corpus is parsed, and base case frames are constructed from reliable predicate-argument examples in the parsing results. Second, case analysis based on the base case frames is applied to the large corpus, and the case frames are upgraded by incorporating newly acquired information. Case frames are gradually fertilized in this way. We constructed case frames from 26 years of newspaper articles consisting of approximately 26 million sentences. The case frames are evaluated manually as well as through syntactic and case analyses. These results presented the effectiveness of the constructed case frames.
