Title: Interpretation of Compound Nominalisations using Corpus and Web Statistics
Speaker: Jeremy Nicholson (University of Melbourne)
Location: ICT Building, Room 2.06
Date: 7 July 2006
Time: 1-2pm
Abstract:
We present two novel paraphrase tests for automatically predicting the
inherent semantic relation of a given compound nominalisation as one of
subject, direct object, or prepositional object. We compare these to the
usual verb--argument paraphrase test using corpus statistics, and frequencies
obtained by scraping the Google search engine interface. We also implemented a
more robust statistical measure than maximum likelihood estimation ---
the confidence interval. A significant reduction in data sparseness was
achieved, but this alone is insufficient to provide a substantial performance
improvement.
