A modular approach to user-defined symbolic periodicity
Speaker: Paolo Terenziani, Universita' del Piemonte Orientale "Amedeo Avogadro", Italy

Abstract:The talk will be split into two main parts. In the first part, I
will briefly survey my current research activity, which mainly
concerns the fields of Artificial Intelligence (Knowledge
Representation, Diagnosis, Temporal Reasoning, Periodic data),
Temporal Databases (Relational Algebrae, Data Semantics), and
Medical Informatics (Clinical Guidelines). In the second part, I
will discuss a specific topic concerning a modular approach to cope
with user-defined symbolic periodicities. User-defined calendars
and periodicities are gaining an increasing relevance in AI and DB
theory and applications. Thus several representation languages have
been introduced to model them. I identify a set of orthogonal
properties of periodicities; based on these properties I define a
lattice of classes of periodicities and use it in order to classify
different symbolic approaches in the literature. For each property I
introduce a language operator, thus proposing a modular family of
symbolic languages, one for each subset of operators. This induces
a lattice of new languages. Each language in the second lattice
defines exactly all and only the periodicities in the homologous
class in the first lattice.
Biography:Paolo Terenziani was born in Turin (Italy) on July 4th, 1963. In
1987, he got the Degree in Computer Science from the University of
Turin (110/110 cum laude). In 1993 he got the PhD in Computer
Science from the same University. In November 1992 he became
Assistant Professor in the Department of Computer Science of the
University of Turin. In November 1998 he became Associate Professor
in the Department of Scienze e Tecnologie Avanzate of the
Universitaâ del Piemonte Orientale âAmedeo Avogadroâ. Since October
2000, he is Full Professor in the Department of Computer Science of
such a University. Paolo Terenzianiâs research activity started in
1987 and has mainly focused on the areas of Artificial Intelligence,
Databases, and Medical Informatics. As regards Artificial
Intelligence, his activity initially concerned Natural Language
Understanding. After the PhD thesis, he switched to the area of
Knowledge Representation, with specific attention to the fields of
temporal reasoning (constraint propagation algorithms, treatment of
periodicity) and diagnosis. In the field of DataBases, he mainly
focused on the extension of âstandardâ relational models and
algebrae to deal with time-related phenomena, and with the semantics
of temporal databases. As regards Medical Informatics, since 1997 he
is involved with Azienda Ospedaliera S. Giovanni Battista in Turin
(the second hospital in Italy, as regards dimensions) in a long-term
project for the development of a semi-automatic manager of clinical
guidelines. Paolo Terenziani published more than 60 papers about
these topics in refereed international journals and conference
proceedings. As a recognition of his research merits, in 1998 he got
the annual "Artificial Intelligence Prizeâ from the Italian
Association for Artificial Intelligence.
