This volume contains a selection of the papers presented at the fifteenth installment of Computational Linguistics in the Netherlands, held at Leiden University on Friday, December 17th, 2004. Organized by the computational linguists of what was at that time called the Leiden Centre for Linguistics (ULCL), this one day conference attracted 74 abstracts from no less than four continents, and over one hundred participants.

The 16 papers in this volume present a state of the art overview of research in different subfields of the broad field of Computational Linguistics, including (computational) phonology, prosody, syntax, semantics, phraseology, machine learning, and text analysis.
