Constraint based integration of deep and shallow parsing techniques
Michael Daum, Kilian A. Foth, Wolfgang Menzel · 2003
To investigate the contributions of taggers or chunkers to the performance of a deep syntactic parser, Weighted Constraint Dependency Grammars have been extended to also take into consideration information from external sources. Using a weak information fusion scheme based on constraint optimization techniques, a parsing accuracy has been achieved which is comparable to other (stochastic) parsers.
