Position: Full-time Researcher (permanent)
Personal:
Fabrizio Sebastiani (born 1960) graduated in Computer Science at the
University of
Pisa in 1986. Up to 1988 he worked as an associate researcher at the
Department of
Linguistics of the University of Pisa. Since 1988 he has been a member of the
research staff of the Information Systems Division of IEI-CNR in Pisa,
working in
the areas of natural language processing, knowledge representation and
reasoning in
artificial intelligence, non-monotonic reasoning and logic-based information
retrieval. From September 1989 to August 1990 he has been a Visiting Research
Scientist at the Computer Science Department of the University of Toronto. From
September 1993 to August 1994 he has been a Visiting Research Scientist at the
Computer Science Department of the University of Glasgow. In academic year
1992/93
he has been (and also is for 1994/95) a Lecturer in Logic and Artificial
Intelligence at the Department of Computer Science of the University of Pisa.
Experience in research projects:
Since 1986 he has been involved in various research projects funded by the
European Economic Community in the area of man-machine communication, databases
and information retrieval. He has been involved in the CFID project, part of the
ESPRIT I program, in the PROMETHEUS project, part of the EUREKA program, and in
the FIDE I project, part of the ESPRIT II Basic Research program. He is
currently
involved in the FERMI project, part of the ESPRIT III Basic Research program and
dealing with foundational issues in information retrieval, in which he is leader
of the WorkPackage "Integration". He is also a member of the MIRO working
group,
funded by the CEC under the ESPRIT III program and dealing with multimedia
information retrieval.
Current Research Context:
The Information Systems Division of IEI-CNR is active in the field of multimedia
and object-oriented databases, information retrieval, library automation, formal
methods for database design, knowledge representation in artificial
intelligence.
In the past, the division has been involved in various ESPRIT projects (MULTOS,
COMANDOS, TODOS), ESPRIT BRA projects (FIDE I) and other European and Italian
research projects. Current European projects in which members of the
division are
involved are:
