Introduction The CorpusEye project (http://corp.hum.sdu.dk ) at the University of Denmark aims at designing and programming an internet based corpus search interface that (1) offers standardised search tools and a unified descriptive formalism across different corpus types and different languages, and (2) allows users to exploit grammatical information in annotated corpora in a user-friendly and menubased way. All corpora in CorpusEye have been annotated with VISL's Constraint Grammar based parsers, in the case of treebanks using an additional PSG module or equivalent (Bick 2003). At the time of writing, the material covers 8 languages and ca. 600 million words.
