This book contains the edited versions of papers presented at the Fourth
Irish Conference on Artificial Intelligence and Cognitive Science
(AICS'91), which was held at University College, Cork, Ireland on 19-20
September 1991. The main aims of this annual conference series are to
promote AI research in Ireland, to provide a forum for the exchange of
ideas amongst different disciplines concerned with the study of
cognition, and to provide an opportunity for industry to see what
research is being carried out in Ireland and how it might benefit from
the results of this research. While most of the participants at the
conference came from universities and companies within Ireland, a
positive feature was the interest shown from outside the country,
resulting in participants from Britain, USA and Italy. The keynote
speaker was Professor James A. Bowen, North Carolina State University,
who spoke on future trends in knowledge representation. The topics
covered in the presented papers included fundamental approaches to AI,
natural language, knowledge representation, information retrieval,
deduction, epistemics and vision. The sponsors of the conference were
Digital Equipment Co. (Galway) and Eolas, the Irish Science and
Technology Board. March 1992 Humphrey Sorensen Contents Section 1:
