Following is a list of selected publications that document DELPH-IN research. While this list aims for a representative snapshot rather than completeness, all DELPH-IN members maintain on-line directories of publications with (in most cases) soft copies of all papers. Please go through the member sites navigator to locate site-specific publication directories or electronic copies where they are not (yet) available from this page.

For a brief summary of recent activities, see an invited talk at COLING 2002 by Hans Uszkoreit. A more in-depth presentation of core DELPH-IN activities is available as an edited collection compiled by Stephan Oepen, Dan Flickinger, Jun-Ichi Tsujii, and Hans Uszkoreit.
