proposed architecture each agent may be
geographically distant, exploring its own ontology,
built up by using different ontology technologies. In
our experimental scenario ontologies were built
using Protégé, WebODE, and OntoEdit.
The Ontology-based Services Agent proposed
here, monitors agents communication and
negotiation, accessing a local ontology and web
services to help whenever the negotiation process is
hard. This may be caused by problems like agents
using different attributes to negotiate the same kind
of product, different currencies to denote different
prices, different units to represent measurement or a
different structural property representations. The
local ontology will be updated whenever new
concepts are discovered, enabling the Ontology-
based Services Agent to use previous knowledge in
the next negotiation rounds.
