In this paper we introduce a semantics for agent communication languages based on social networks, providing us with a principled way to define and reason about their dynamics. As an instance we consider dependence networks, where the social relations represent that an agent depends on another agent to achieve its intentions. We suggest how FIPA semantics can be reconstructed in this social semantics. Our approach reveals that we need special semantics for relations like ownership, authority or fear: all kinds of interesting social relations, not previously studied by multiagent systems. [less ▲]

There are two main traditions in defining a semantics for agent communication languages, based either on mental attitudes or on social commitments. These traditions share speech acts as operators with preconditions and effects, and agents playing roles like speaker and hearer, but otherwise they rely on distinct ontologies. They refer not only to either belief and intention or various notions of social commitment, but also to distinct speech acts and distinct kinds of dialogue. In this paper, we propose a common ontology for both approaches based on public mental attitudes attributed to role instances. Public mental attitudes avoid the unverifiability problem of private mental states, while reusing the logics and implementations developed for FIPA compliant approaches. Moreover, a common ontology of communication primitives allows for the construction of agents which do not need separate reasoning modules to participate in dialogues with both mental attitudes and social commitments compliant agents. Moreover, a common ontology of communication primitives allows for the construction of agents participating in and combining the full range of dialogues covered by the individual approaches without having to redefine the existing protocols to cope with new dialog types. We illustrate how to extend the ontology to a semantics for agent communication and how to define mappings from existing semantics to the new one. [less ▲]

In agent communication languages, the inferences that can be made on the basis of a communicative action are inherently conditional, and non-monotonic. For exam- ple, a proposal only leads to a commitment, on the con- dition that it is accepted. And in a persuasion dialogue, assertions may later be retracted. In this paper we there- fore present a defeasible logic that can be used to express a semantics for agent communication languages, and to efficiently make inferences on the basis of communica- tive actions. The logic is non-monotonic, allows nested rules and mental attitudes as the content of communica- tive actions, and has an explicit way of expressing per- sistence over time. Moreover, it expresses that mental attitudes are publicly attributed to agents playing roles in the dialogue. To illustrate the usefulness of the logic, we reformalize the meta-theory underlying the FIPA se- mantics for agent communication, focusing on inform and propose. We show how composed speech acts can be formalized, and extend the semantics with an account of persuasion [less ▲]

Our goal is to extend agent communication lan- guages for persuasion dialogues. We distinguish action commitments from propositional commit- ments, because both limit future moves, but an action commitment is fulfilled when the hearer believes that the action is performed, whereas a propositional commitment is fulfilled only when the hearer concedes to the proposition – where con- cessions are the absence of a belief to the con- trary, and prevent further challenges. Using a com- mon model for both kind of commitments and a role-based semantics of agent communication lan- guages, we show how propositional commitments are related to public beliefs and action commit- ments to public goals [less ▲]
