Towards Intentional Agents to Manipulate Belief, Desire and Commitment Degrees

The BDI models are among the best known agent's formalizations. They are based on the three mental attitudes: belief, desire and intention. Many of the BDI models do not admit degrees of belief, desire and intention. Parsons and Giorgini gave a semantic to the belief degree but not for desire and intention. The purpose of this paper is to continue the work of Parsons and Giorgini, by including desire and intention degrees. Another improvement of the BDI formalization is to add the emotion and physical state to the elements influencing the decision making. We illustrate the interaction between all these different concepts by proposing the (CDI)° architecture.
