Abstract in Portuguese
Agentes inteligentes é um termo guarda-chuva que agrega diversas pesquisas no desenvolvimento de softwares autônomos que utilizam técnicas de Inteligência Artificial a fim de satisfazer metas estabelecidas por seus usuários. A construção de sistemas baseados em agentes inteligentes é uma tarefa complexa que envolve aspectos como comunicação entre agentes, planejamento, divisão de tarefas, coordenação, representação e manipulação de conhecimento e comportamentos, entre outras tarefas. Plataformas para agentes prevêem alguns serviços que permitem a desenvolvedores construir soluções sem a necessidade de se preocupar com todos detalhes da implementação. Um novo modelo para criação de agentes chamado 'agentes atômicos' é proposto com o objetivo de oferecer flexibilidade para o gerenciamento de conhecimento e implementação de comportamentos. A arquitetura Agentes Semânticos provê um framework para a implementação de tal modelo, oferecendo um conjunto de ferramentas para a criação de agentes inteligentes. Um protótipo de plataforma para agentes, baseado em tal arquitetura, foi desenvolvido em Java e permite a criação de aplicações capazes de processar linguagem natural restrita, manipular conhecimento e executar ações úteis.

Abstract in English
Intelligent Agents is an umbrella term that aggregates different research on the development of autonomous software that uses Artificial Intelligence techniques in order to satisfy user requests. The construction of systems based on intelligent agents is a complex task that involves aspects such as agent communication, planning, work division, cooperation, epresentation and manipulation of knowledge,among other activities. Agent Platforms provide some services that allow developers to build solutions without the need of worrying about every implementation detail. A new model for creating agents, called 'atomic agents', is proposed with the goal of offering flexible knowledge management and behavior implementation for constructing software agents. The Semantic AgentArchitecture provides a framework for the implementation of such model, offering a set of tools for the creation of intelligent agents. A prototype Agent Platform, based on the architecture, was developed in Java and allows the creation of applications that are able to process restricted natural language, manipulate knowledge and execute useful actions.
