....a role is missing from one side or the other, or cases in which input or task model has more than one value are also allowed) The core speech acts that are currently modelled include assert, info request, order, request and suggest. Unlike many accounts of the effects of these speech acts (e.g. [8, 1, 7, 13]) there are no direct effects on the beliefs, desires or intentions of the conversational participants. This allows for the possibility that participants are insincere in their utterances. Following [34] the direct effects involve social commitments, and one may then infer from these commitments ....

As a reaction against this, in both the software agents and human computer arenas, ....

....modules, and their interaction with each other. A very challenging task is to chose a suitable representation framework for semantic pragmatic information extracted from the analyzed text. Based on the assumption that linguistic interaction can be represented by speech or dialogue acts (see [CP79] it could be worthwhile to see how to integrate a non monotonic temporal reasoning system such like Features and Fluents (see [San94] within such a framework. This should be feasible, since the system Fluent Logic Programming (see [PT98] is already designed with the same backbone as that used ....

....To conclude: speech acts apparently cannot be individuated by their effects, but only by their preconditions. 1.4 Planning a Speech Act The theory of an agent communicating crucially depends on being able to determine what FPs are currently satisfied. The general picture (due historically to [5], see [3] for discus sion) is this. An agent desires to have the environment have a certain feature. This desire is not necessarily a part of the communication process. it may have come about through other means such as being a feature of its design or being ordered by some outside agency. The ....

....Cohen, and Perrault Allen, Cohen, and Perrault were the first to computationalize the theory of speech acts. They showed [CPA82] that, in question answering systems, users expected the system to recognize their unstated goals in order to provide more helpful responses to questions. Cohen [Coh78, CP79] concentrated on using plan synthesis together with speech acts for natural language generation. Allen [All79, AP80, All83] on the other hand, used plan recognition of speech acts for natural language understanding. We will concentrate here only on Allen s work. Allen studied transcripts of ....

....of the same program with a range of di erent semantics, and thus to investigate the implications of di erent semantics. The basic model we use for de ning semantics is a strips style pre post condition formalism, in the way pioneered for the semantics of speech acts by Cohen and Perrault [2], and subsequently applied to the semantics of the kqml [3] and fipa [5] languages. Thus, to give a semantics to performatives in MABLE, a user must de ne for every such communicative act a pre condition and a post condition. Formally, the semantics for a communicative act CA are de ned as a ....

....theory of reference is a theory that specifies and explains the human competence to nse referring expressions in order to achieve certain goals. Since the relation between referring expressions and speaker s goals is what needs explaining, it is natural to consider referring as planned action [1,4,5]. This, in turn, requires showing how the use of referring expressions is systematically related to changes in the hearer s mental state. For that purpose, we need to know the speaker s goals concerning the hearer s mental state, and therefore, a pragmatic theory of referring must first of all ....

....created by the use of particular relations are a kind of precondition to using a particular means. Goal pursuit methods are well precedented in artificial intelligence, in both linguistic and nonlinguistic domains [Appelt 81, Allen 78, Cohen 78, Cohen Perrault 77, Perrault Cohen 78, Cohen Perrault 79, Newell Simon 72] We expect to be able to create the constructive part of RST by mapping the existing part of RST onto AI goal pursuit methods. In particular computational domains, it is often easy to locate formal correlates for the notions of evidence, elaboration, condition, and so ....

....In the mental approach, so called agent s mental structures (e.g. beliefs, desires and intentions) are used to model conversations and to define a formal semantics of speech acts. In the first system that was based on these notions, speech acts were planned like non communicative actions [9]. It was used by [19] and [20] to define a formal semantics of KQML. However, this semantics has been criticized for not being verifiable because one cannot verify whether the agents behavior matches their private mental states [12] 5] An alternative to the mental approach was proposed by [29] ....

....know, and thereby causes a revision to the beliefs of the listener. Speech act theory classi es utterances according to their pre conditions and e ects, and has been used to provide a semantics for agent utterances, particularly in work by Philip Cohen, Hector Levesque and Raymond Perrault [10, 11]. Drawing on this work, the FIPA ACL Semantic Language SL is a modal logic formalism which de nes pre and post conditions for the 22 locutions of the language in terms of the beliefs, desires and uncertain beliefs of the agents participating in a dialogue using the language. For example, the ....

....Planner) has been developed that can plan utterances similar to example (1) above, coordinate the linguistic actions with physical actions, and know that the utterance it plans will have the intended multiple effects on the hearer. KAMP builds on Cohen and Perranlt s idea of planning speech acts [4], but extends the planning activity down to the level of constructing surface English sentences. A detailed description of the en tire KAMP system can be found in [2] The system has been implemented and tested on examples in a cooperative equipment assembly domain, such as the one in example ....
