15th International Florida Artificial Intelligence Research Society

Special Track : "Categorization and Concept Representation :
Models and Implications"
 ===========================================================================
==================


This track seeks to bring together researchers working on issues related to
categorization and concept representation in the areas of Artificial
Intelligence and Cognitive Psychology.

Topic Description
------------------

Categorization is the process by which distinct entities are treated as
equivalent. It is one of the most fundamental and pervasive cognitive
activities. It is fundamental because categorization allows us to understand
and make predictions about objects and events in our world. The problem of
understanding what criteria are used to group together entities in the same
category is indeed central in categorization. Though most works on this
topic have proposed that perceptual or structural similarity is the "glue"
that binds objects of a same category, some psychologists have claimed that
similarity is insufficient to account for the acquisition and use of
categories and have proposed more abstract forms of criteria that make
categories coherent and give them a kind of homogeneity in terms of the
entities that belong to them.

The different new proposals psychologists have suggested are that objects
are grouped together because they facilitate a common goal or serve the same
function. Some categories are viewed as coherent because they rest on a
theory which explains the commonalities of their elements. Similarity and
goals, on the one hand, and theories, on the other hand, have not been paid
the same attention in computational models of categorization.
Similarity-based models abound and the notion of categorization goals has
also been exploited in computational models. On the other hand, the notion
of an underlying theory that makes a category coherent is just beginning to
be further analyzed and specified.  New computational models of
categorization reflecting this new tendency are thus expected.

The representation of concepts that a categorization system generates is of
course intimately tied to the criteria this system uses to group entities
into categories, so along with new models of categorization, we expect to
see the emergence of new models of concept representation apart from the
classical ones deriving from the Aristotelician, the Prototypical and the
Exemplar Views. The representation of the entities to categorize also plays
an important part in the categorization process. In particular, the context
in which the entities occur may influence the way they are classified.

The purpose of this track is to bring fresh insights concerning a perhaps
revisited notion of similarity, the way goals of categorization influence
this process, how the notion of the theory of a concept can be formalized
and implemented in computational models of categorization and the
implications those elements may have on the representation of concepts.
The contributions to this track may be situated in either symbolic or
connectionist approaches to categorization.

Contributions in the following sub-topics would be welcomed :
- Computational models of similarity,
- Computational models of theory-based categorization,
- Computational models of similarity-based categorization,
- Computational models of human categorization,
- Models of concept representation which are relevant to the process of
categorization,
- Models of concept representation and elicitation,
- Formalization of the notion of theory which underlies a category,
- Formalization of the context of occurrence of the entities to be
categorized and their influence on the categorization process.

This list is not exclusive provided that the contributions are relevant to
the definition of the track specified above.


Paper Review and Publication
------------------------------
Only full papers will be considered for the track. Submitted papers will be
reviewed by two program committee members. An author for an accepted paper
is expected to present the paper in the track. Papers accepted for the track
will be published in the FLAIRS 2002 Conference Proceedings.

The best papers will be invited for modification, extension and submission
to a special issue in JETAI (Journal of Experimental and Theoretical
Artificial Intelligence).
