Acquiring Reliable Predicate-argument Structures from Raw Corpora for Case Frame Compilation

We present a method for acquiring reliable predicate-argument structures from raw corpora for automatic compilation of case frames. Such lexicon compilation requires highly reliable predicate-argument structures to practically contribute to Natural Language Processing (NLP) applications, such as paraphrasing, text entailment, and machine translation. We first apply chunking to raw corpora and then extract reliable chunks to ensure that high-quality predicate-argument structures are obtained from the chunks. Our experiments confirmed that we succeeded in acquiring highly reliable predicate-argument structures on a large scale.
