2005 AAAI Fall Symposium
Roles, an interdisciplinary perspective
II Call for papers
November 3-6, 2005, Hyatt Crystal City in Arlington, Virginia
The notion of role is ubiquitous not only in many areas of artificial
intelligence, but also in many other areas of computer science, like
programming languages, software engineering, coordination and databases,
multiagent systems, computational linguistics and conceptual modelling,
and also in other scientific fields, like formal ontology, sociology,
cognitive science, organizational science and linguistics.
In sociology, on the one hand roles are often described as expected
behavior of entities or agents, on the other hand roles are seen also as
presentations of selves. In organizational science roles encompass more
formal aspects such as rights and duties. Three different main
viewpoints characterize research on roles:
* roles as named places in relationships (especially in linguistics,
databases and conceptual modelling)
* roles as dynamic classification of entities (especially in
programming languages and databases)
* roles as instances to be adjoined to the entities which play the
role (especially in ontologies, multiagent systems and programming
Undisputed distinguishing features of roles seem to be their dependence
on some other entities and their dynamic character (Sowa 1984). These
properties contrast roles with the notion of natural types. Natural type
seems to be essential to an entity: if an entity changes its natural
type, it loses its identity; in Guarino (1992)'s terms, roles lack the
rigidity which natural types possess. Masolo et al. (2004) elaborate the
relational nature of roles, highlighting their definitional dependence
on other concepts.
Discussions on roles are important not only to have a better
understanding of theories using this notion, but also from the
applicative point of view. E.g., integration of ontologies, programming
languages, databases, simulation can benefit from the introduction of a
well founded notion of role.
However, as, e.g., Steinmann (2000) witnesses, there is no common
agreement yet about what roles are, which are their properties and how
they can be modelled in a uniform way in the different areas. One likely
reason is that roles are discussed in very different contexts, so that
interested researchers have little opportunity to meet with each other.
Even if there are events where roles are discussed, they always appear
as a sub-topic within the framework of more general issues (like the
AOSE workshop about agent oriented software engineering, or the recent
CoOrg05 <http://boid.info/CoOrg05> workshop at Coordination05); hence,
there are few venues for research integration.
With this symposium we propose to gather researchers working across the
boundaries of their subfields to explore new formal and computational
techniques and research methodologies for integrating research results.
For this reason this symposium will provide time for discussion besides
Researchers interested in making a presentation should submit a paper
about theoretical or applicative issues (not to exceed 5,000 words).
Other participants should submit either a position paper or a research
abstract in order to be involved in the discussion. Submissions should
be uploaded at http://roles05.di.unito.it/
Questions should be sent to Guido Boella (guido [at] di.unito.it).
Papers will be published in the symposium proceedings and the best
papers of the symposium will be selected for publication on some renowed
journal. Participants from all parts of the AI community as well as from
other fields are encouraged. Instructions for authors can be found at
