Thesis

• Collaborative and Corpus-Driven Approaches towards Lexicalized Grammar-based Natural Language Processing
  Ph.D dissertation. University of Tokyo. March, 2005
  1,547,734 bytes, PDF (183 pages)
  
  This thesis involves an LTAG-to-HPSG conversion (published as a journal titled `Grammar Conversion from LTAG to HPSG') and its application to parsing comparison (published as a journal titled `Parsing Comparison across Grammar Formalisms using Strongly Equivalent Grammars') as Part I, and a filtering method for subcategorization acquisition (published as a paper titled 'Improving the Accuracy of Subcategorizations Acquired from Corpora') and a PLSA-based probabilistic subcategorization lexicon (published as a paper titled `Towards Accurate Probabilistic Lexicons for Lexicalized Grammars') as Part II. The part related to grammar conversion is further elaborated through comparison to related research.
