Posit spaces: a performative model of e-commerce

What distinguishes e-commerce from ordinary commerce? What distinguishes it from distributed computation? In this paper we propose a performative theory of e-commerce, drawing on speech act theory, in which e-commerce exchanges are promises of future commercial actions, whose real-world meanings are constructed jointly and incrementally. We then define a computational model for this theory, called Posit Spaces, along with the syntax and semantics for an agent interaction protocol, the Posit Spaces Protocol or PSP. This protocol enables participants in a multi-agent commercial interaction to propose, accept, modify and revoke joint commitments. Our work integrates three strands of prior research: the theory of Tuple Spaces in distributed computation; formal dialogue games from argumentation theory; and the study of commitments in multi-agent systems.
