My master thesis describes the development and optimisation of a shallow syntactic parser for spoken Dutch. The parser performs part-of-speech tagging, syntactic chunking, and grammatical relation finding. A similar system for written English, developed over the years within the ILK group served as a starting point; it comprises several modules, each trained to perform one of the parsing subtasks, all of them built on top of a memory-based learner. A good overview of this English memory-based shallow parser is presented in [DBV99].

The Dutch memory-based shallow parser has been trained on the Spoken Dutch Corpus (Dutch: Corpus Gesproken Nederlands, or CGN), a large corpus of contemporary spoken Dutch of which approximately a million words have received full syntactic annotation. Based on training material extracted from this annotation, both features and parameters were optimised.
