Gene annotation is a process that encompasses multiple approaches on the analysis of nucleic acids or protein sequences in order to assign structural and functional characteristics to gene models. When thousands of gene models are being described in an organism genome, construction and visualization of gene networks impose novel challenges in the(More)
The attacks detection and prevention problem could be improved using new intelligent techniques. This paper aims to define an ontology model for intrusion correlation over intelligent multiagent system. The semantic model describes attacks signatures, reaction rules, axioms with alerts communication and correlation. The proposed model optimizes the alerts(More)
This paper presents the development of a cognitive and collaborative filtering system that uses retrieval and filtering algorithms implemented in a multiagent system that runs in a distributed environment developed by using the GAIA methodology, which allows to identify agents, communication protocols, behaviors, and roles of each entity within the system.(More)
