The BDI architecture, which is founded on the symbolic model, represents a consolidated model that counts upon substantial theoretical-practical contributions. However, according to G?rdenfors, despite its strengths, there are some aspects of the cognitive phenomena which give rise to the need of a conceptual model that has to establish itself between the perceptual and the symbolic levels. Taking into account the principle that recognition of objects can be set as a process of concept formation, this thesis comprises the design and implementation of a knowledge representation model for BDI agents based on the assumptions of the paradigm of conceptual spaces. In this sense, the actual approach seeks to establish the necessary mechanisms for the development of this model through the use of the Jason platform and the programming language CSML. From the issues which are inherent to the development of an application directed to the aid of visually impaired people, this thesis aims to evaluate the implications of the building processes of the conceptual inference model for BDI agents. / A arquitetura BDI ? a estrat?gia preferencial no que tange ao desenvolvimento de agentes situados em ambientes complexos e din?micos. Alicer?ada no modelo simb?lico, a arquitetura BDI representa um modelo consolidado que conta com um substancial aporte pr?tico-te?rico. Entretanto, conforme assinala G?rdenfors, apesar da robustez desse modelo, h? aspectos do fen?meno cognitivo que suscitam a necessidade de um modelo conceitual que estabelece-se entre os n?veis simb?lico e perceptual. Partindo do princ?pio de que o reconhecimento de objetos pode ser assinalado como um processo de forma??o de conceitos, esta tese abrange a concep??o e a implementa??o de um modelo de representa??o do conhecimento para agentes BDI com base nos pressupostos do paradigma dos espa?os conceituais. Nesse sentido, esta abordagem busca estabelecer atrav?s da plataforma Jason e da linguagem de programa??o CSML os mecanismos necess?rios para o desenvolvimento desse modelo. A partir da problem?tica inerente ao desenvolvimento de uma aplica??o voltada ao aux?lio de pessoas cegas, esta proposta busca avaliar as implica??es do processo de constru??o do modelo de infer?ncia conceitual para agentes BDI.
