Abstract:

In an earlier study, we described a method to create a parsing lexicon from semantic-based lexicon using manual rules. This paper describes an automated mapping methodology for the same purpose. Our approach maps lexical entries in a large LCS-based repository of semantically classified verbs to their corresponding syntactic patterns automatically. We evaluate the accuracy and coverage of this lexicon using LDOCE syntactic codes as a gold standard. We show that this lexicon is comparable to the hand-generated Minipar lexicon i.e., similar recall and precision values. We also present the effects of using such a lexicon on the parser performance. The advantage of automating the process is that the same technique can be applied directly to lexicons we have for other languages, for example, Arabic, Chinese, and Spanish. The results indicate that our method will help us generate parsing lexicons which can be used by a broad-coverage parser that runs on different languages.
