Abstract


It has previously been claimed that agent technologies facilitate software development by virtue of their high-level abstractions for interactions. We address a more specific characterization and utility. We believe that it is important to distinguish agent technologies from other software technologies by virtue of a set of unique software characteristics. This is in contrast to much in the literature that concentrates on high-level characteristics that could be implemented with a variety of software techniques.

Agent-based software engineering (ABSE), for at least an important class of agents and applications, can be characterized by both model and inner/outer language components. Our experience in developing applications based on long-term asynchronous exchange of agent messages, similar to typical email usage, leads us to believe these unique characteristics facilitate useful software development practices. The utility derives from a stratification of change among the components, ease of collaborative change and debugging even during runtime due to asynchronous text parsing-based message exchange, and reuse of the outer language as well as generic agents as a programming environment.
