Preface
This volume contains the papers prepared for the Sixth Conference of the European Chapter
of the Association for Computational Linguistics, held 19-23 April 1993 in Utrecht. The
Programme Committee received a large number of submissions (5 page extended abstracts)
from all over the world. The general quality of the submissions was high. Out of a total of
229 submissions, 47 were accepted, including 7 reserve papers. Every abstract submitted
was reviewed by one member of the Programme Committee and three referees (see pages
v and vi). Electronic submission and reviewing procedures helped to speed up this process
and turned out not to cause an unreasonable work load at our centre. We trust that the
resulting programme offers an inspiring cross-section of excellent work in the field.
The programme features invited talks and thematic sessions around two prominent themes

in contemporary research: the relations between logic and computational linguistics, and
the use of data-oriented methods in CL. The thematic orientation is further developed in
the tutorial sessions which are scheduled the days preceding the conference (19-20 April
1993). New elements compared to the predecessors of this conference are a separate student
session and a poster and demo session; the reader will find the selected student papers and
the poster/demo abstracts at the end of the Proceedings. The programme further includes
an information session on infrastructural initiatives in the area of computational linguistics,
and the general ACL Meeting. The temporal organisation of the programme is designed to
maximize coherence within and diversity across the two parallel sessions.
Many people contributed to the preparations of this meeting, and we are happy to thank
them: Don and Betty Walker, who promptly replied to our frequent (21366 words) appeals
for advice, without which the organisation would have been extremely difficult; Jan van
Eijck for organising the tutorials; the 11 members of the Programme Committee and the
93 referees; Johan van Benthem, Ken Church and Ivan Sag for the invited talks; Jeroen
Groenendijk and Martin Stokhof, Mark Liberman and Yves Schabes, Leen Torenvliet, and
Hans Uszkoreit for giving tutorials; Anne-Marie Mineur and Yvon Wijnen for organising the
student sessions (see separate preface); Toon Cohen, Sieb Nooteboom and Peter Schelleman
for helpful advice; Erik Aarts, Henny Bekker, Laura Bloksma, Nadine Buenen, Crist-
Jan Doedens, Joke Dorrepaal, Maria Florenza, Tertius Groenman, Dirk Heylen, Heleen
Hoekstra, Anne-Marie Mineur, Ren6e Pohlmann, Herbert Ruessink, Andr6 Schenk, Koen
Versmissen and Jules van Weerden for assistance with local organisation.

Student Session
Preface
This year for the first time the European Conference of the ACL includes a student session.
This part of the conference was organized by the Dutch Student Association for Computa-
tional Linguistics. The student session differs from the main conference in its emphasis on
promising work in progress.
For this Student Session we received 34 submissions, 6 of which were accepted. We would
like to thank the authors for their submissions. An equally important contribution was made
by the Student Programme Committee. Every paper was read by 3 of the 18 student referees,
whom we recruited from all over Europe. Thanks to their efforts, we were able to make a
well-informed decision about which papers to select.
Also we would like to thank the organizers of the main conference, who supported us with
their advice and guidance throughout the preparations of the session.
We hope future EACL Conferences will continue this initiative for we believe it is of
great value for young researchers to get an opportunity to present their work to a large
and knowledgeable audience and to exchange ideas with fellow students as well as senior

researchers.
