Abstract

In this paper we will discuss the context management features of the new logic programming language DALI, aimed at defining agents and multi-agent systems. In particular, a DALI agent, which is capable of reactive and proactive behaviour, builds step-by-step her context. Context update is modelled by the novel concept of “evolutionary semantics”, where each context manipulation is interpreted as a program transformation step. We show that this kind of context-based agent language is well-suited for representing many significant commonsense reasoning examples.
