Tracy Holloway King, Palo Alto Research Center, "Engineering Deep

Grammars"

ABSTRACT

Parsing systems based on deep grammars mark explicitly a variety of syntactic and semantic dependencies and should therefore provide crucial support for meaning-sensitive NLP applications. However, common wisdom has it that parsing systems based on deep linguistic grammars are too difficult to produce, lack coverage and robustness, are massively ambiguous, and have poor run-time performance. In this talk, I will discuss ways in which deep grammars can be engineered to overcome these problems, focusing on techniques used in the implementation of the broad-coverage LFG-based grammars produced by the ParGram project.
