A Maximum-Entropy Partial Parser for Unrestricted Text
Autor: Wojciech Skut and Thorsten Brants

This paper describes a partial parser that assigns
syntactic structures to sequences of part-of-speech tags. The program
uses the maximum entropy parameter estimation method, which allows a
flexible combination of different knowledge sources: the hierarchical
structure, parts of speech and phrasal categories. In effect, the
parser goes beyond simple bracketing and recognises even fairly
complex structures. We give accuracy figures for different
applications of the parser.
