Integración de Ontologías y Capacidades de Razonamiento en Agentes de Software Inteligentes para la Simulación del Proceso de Negociación de Contratos de Energía Eléctrica.

The use of Ontologies becomes to be essential facing the inherent complexity of Multi-Agent applications that have been developed. This is due to the following issues: abundance of communication between agents, semantic interoperability of systems and platforms, and semantic problems. However, to manually construct the Ontologies following the specifications of the JADE (Java Agent DEvelopment framework) platform is a very expensive task. That is why, in this paper, it is proposed its development by means of its modeling with the Protégé tool, and then, its integration with the JADE framework. This integration is facilitated by the Bean Generator plug-in, which allows to automatically generating code. In addition, the implementation of reasoning mechanisms in deliberative agents can be reached by means of JADE y JESS (Java Expert System Shell) frameworks integration. In fact, with those it is possible to build hybrid software agents (reactive + deliberative) using rule based reasoning mechanisms. Thus, the aim of this paper is to illustrate and underline the advantages when integrate previous three tools and its validation using a concrete study case: the Simulation of Electric Energy Contracts Negotiation Process.
