Integration


Intelligent, web services based agents

a software entity that carries
out some set of operations
on behalf of a user or
another program with some
degree of independence or
autonomy, and in so doing,
employing some knowledge
or representation of the
user’s goals or desires

Implementation of the IADE



An Intelligent Agent Development Environment has been implemented which
is built on the JADE agent platform


Two applications


Communities of Practice and Web Services, as part of a
knowledge management system.


Web Services return explicit knowledge from which a user can formulate a
request for tacit knowledge to be returned by an expert through the CoP
applications.


Admin and user GUI has been written to allow admin of the agents and
ontology manipulation for Web Services.
