Abstract |
We present a method for acquiring reliable predicate-argumentstructures from raw corpora for automatic compilation of caseframes. Such lexicon compilation requires highly reliablepredicate-argument structures to practically contribute to NaturalLanguage Processing (NLP) applications, such as paraphrasing, textentailment, and machine translation. However, to precisely identifypredicate-argument structures, case frames are required. This issue issimilar to the question "what came first: the chicken or the egg?" Inthis paper, we propose the first step in the extraction of reliablepredicate-argument structures without using case frames. We firstapply chunking to raw corpora and then extract reliable chunks toensure that high-quality predicate-argument structures are obtainedfrom the chunks. We conducted experiments to confirm the effectivenessof our approach. We successfully extracted reliable chunks of anaccuracy of 98% and high-quality predicate-argument structures of anaccuracy of 97%. Our experiments confirmed that we succeeded inacquiring highly reliable predicate-argument structures that can beused to compile case frames. |
