    ABSTRACT: This paper proposes an ontology model for representing intrusion detection events and prevention rules, integrating multiagent systems based on unsupervised and supervised techniques for classification, correlation and pattern recognition. The semantic model describes attacks signatures, reaction tasks, axioms with alerts communication and correlation; nevertheless we have developed the prevention architecture integrated with another security tools. This article focuses on the approach to incorporate semantic operations that facilitate alerts correlation process and providing the inference and reasoning to the ontology model.

    ABSTRACT: The so-called "Coffee Triangle" region is located in the Andean Region, in central Colombia, South America. This Andean Region is composed of the Departments of Caldas, Quindío and Risaralda. The Andean Region has been characterized by the production of coffee as a worldwide industry supported by high Quality and Research standards. These components have become the key bastions to compete in international markets. After the decline of the Coffee industry it is necessary to consider alternatives, supplemented by the success of the Software Industry at the global level. The strengthening of the Software Industry in the Coffee Triangle seeks to establish a productive alternative for regional growth in a visionary way, where knowledge, a fundamental input of the Software Industry, is emerging as one of the greatest assets present in this geographical area - Andean Region - of Colombia.

    ABSTRACT: This paper discusses how to manage the knowledge associated with dimensions: social, natural, cultural, political, intellectual and physical of local communities. The portal manages communities of practice through collaborative environments, content management, applications on line and intelligence to community, learning environments, relations based on social multi-agent systems and ontologies with semantic representation. Multi-agent systems enable participation and empowerment for e-government, e-business, e-participation and e-learning; the multiple roles aim to reach activity behavior by changing the passive observer becoming a dynamic individual co-constructor of the domain knowledge. The social collaboration process using multi-agent technologies provides distribution, cooperation, intelligence, pro-activity, reactivity, scalability, adaptability among others properties; offering a decentralized model own community interaction; agents perceive and influence aspects of their distributed environment, and learn about it. Multi-Agent Portal systems based on social simulation can improve the recent models incorporating cognitive architectures, as they provide a realistic basis for modeling individual agents and therefore their social interactions.
