    <pub:abstract><![CDATA[Both conversation specifications and policies are required to facilitate
effective agent communication. Specifications provide the order in which
speech acts can occur in a meaningful conversation, whereas policies restrict
the specifications that can be used in a certain conversation based
on the sender, receiver, messages exchanged thus far, content, and other
context. We propose that positive/negative permissions and obligations
be used to model conversation specifications and policies. We also propose
the use of ontologies to categorize speech acts such that high level policies
can be defined without going into specifics of the speech acts. This approach
is independent of the syntax and semantics of the communication
language and can be used for different agent communication languages.
Our policy based framework can help in agent communication in three
ways (i) to filter inappropriate messages, (ii) to help an agent to decide
which speech act to use next, and (iii) to prevent an agent from sending
an inappropriate messages. Our work differs from most existing research
on communication policies because it is not tightly coupled to any domain
information such as the mental states of agents or specific communicative
acts. Contributions of this work include (i) an extensible framework that
is applicable to varied domain knowledge and different agent communication
languages, and (ii) the declarative representation of conversation
specifications and policies in terms of permitted and obligated speech acts.]]></pub:abstract>
