Abstract

Communicative acts-based ACLs specify domain-independent information about communication and relegate domain-dependent information to an unspecified content language. This is reasonable, but the ACLs cover only a small fraction of the domain-independent information possible. As a key element of modern ACLs, the set of communicative acts needs to be as complete as possible to allow agents to communicate the widest range of information with agreed-upon semantics. This paper describes a new approach to broaden the semantic coverage of agent communicative acts. It provides agents with the ability to express more of the semantics of human languages and yields a more powerful ACL. We first describe the main meaning categories and semantics for an ACL, which we derive from prior work on speech-act classifications. Next, we prove the resultant semantic coverage. Finally, we present some example applications, which demonstrate that the approach can combine the benefits of the FIPA ACL with Ballmer and Brennenstuhl’s speech act classification, resulting in a more expressive and efficient ACL.
