Abstract: Social insect societies and
more specifically ant colonies, are distributed systems that, in spite
of the simplicity of their individuals, present a highly structured
social organization. As a result of this organization, ant colonies can
accomplish complex tasks that in some cases exceed the individual
capabilities of a single ant. The study of ant colonies behavior and of
their self-organizing capabilities is of interest to knowledge
retrieval/management and decision support systems sciences, because it
provides models of distributed adaptive organization which are useful
to solve difficult optimization, classification, and distributed
control problems, among others. In the present work we overview some
models derived from the observation of real ants, emphasizing the role
played by stigmergy as distributed communication paradigm, and we
present a novel strategy to tackle unsupervised clustering as well as
data retrieval problems. The present ant clustering system (ACLUSTER)
avoids not only short-term memory based strategies, as well as the use
of several artificial ant types (using different speeds), present in
some recent approaches. Moreover and according to our knowledge, this
is also the first application of ant systems into textual document
clustering.
Keywords: Ant Systems, Unsupervised
Clustering, Swram Intelligence, Data Retrieval, Data Mining,
Distributed Computing, Ant-based Clustering, Document Maps, Textual
