%0 Journal Article %T Considerations on Construction Ontologies %A Alexandru Cicorta£¿ %A Victoria Stana Iordan %A Alexandra Emilia Forti£¿ %J Annals. Computer Science Series %D 2009 %I Mirton Publishing House, Timisoara %X The paper proposes an analysis on some existent ontologies, in order to point out ways to resolve semantic heterogeneity in information systems. Authors are highlighting the tasks in a Knowledge Acquisiton System and identifying aspects related to the addition of new information to an intelligent system. A solution is proposed, as a combination of ontology reasoning services and natural languages generation. A multi-agent system will be conceived with an extractor agent, a reasoner agent and a competence management agent. %U http://anale-informatica.tibiscus.ro/download/lucrari/7-1-09-Cicortas.pdf
