  • Introduction to Grammatical Formalisms for Natural Language Parsing
  • Giorgio Satta, Department of Information Engineering, University of Padua, Italy

Abstract:
In the field of natural language parsing, the syntax of natural languages is

modeled by means of formal grammars and automata. Sometimes these formalisms

are borrowed from the field of formal language theory and are adapted to the
task at hand, as in the case of context-free grammars and their lexicalized
versions, where each individual rule is specialized for one or more lexical
items. Sometimes these formalisms are newly developed, as in the case of
dependency grammars and tree adjoining grammars. In this talk, I will
briefly overview several of these models, discussing their mathematical
properties and their use in parsing of natural language.
