支持多Agent通信的扩展BDI逻辑

An Extended BDI Logic for Modeling Multi-agent Communication

ＢＤＩ（信念、期望和意图）逻辑是当前ａｇｅｎｔ理论研究的热点课题之一，相关研究工作较少涉及对ａｇｅｎｔ间通信的描述．文章旨在提出一个能表示和推理多ａｇｅｎｔ间基于言语行为理论的通信行为的扩展ＢＤＩ逻辑．该逻辑是一个多类、带量词并具有分枝时序结构的一阶多模态逻辑，除了包含标准ＢＤＩ逻辑的模态和时态算子之外，还引入了一些必要的逻辑算子和构造符，用于刻画ａｇｅｎｔ为实现其意图而具有的规划能力，以及对多ａｇｅｎｔ通信给出正确的语用解释．文章讨论了逻辑的语法和语义。

Although BDI approach is currently a subject of much ongoing research, less relative works about modeling communication have been involved. The aim of this paper is to extend classical BDI logic for representing and reasoning about speech act interactions between multi agents. A many sorted, quantified, first order, multi modal logic with branching time structure is presented, including standard BDI modal and temporal operators like belief, goal, intention, etc. In addition, some operators and constructs are introduced for characterizing agents' “know how” or having plans about how to achieve their intentions and for interpreting the pragmatic meanings of inter agent communication. While discussing the syntax and semantics of the logic, some kinds of illocutionary speech acts are logically classified and interpreted.
