In this we propose a software architecture to support the Groups in meetings of Ideas Generation in an Ambient Intelligence context. The main issue is how the explicit information, that already exists in the meetings, is represented in order to be easily accessed for future usage. This enables environments in the context of work (Meeting Rooms) to be able to review the past, to be aware of the current context and to be able to propose solutions/ideas for future meetings. The knowledge management is achieve by means of intelligent agents, which must perform tasks such as building knowledge on Domain Ontologies, finding related/equal/opposite issues on indexed knowledge, and delivering the knowledge to the users in appropriate time.
