Agent-based software engineering

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 longterm 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.1 © 2001 Springer Berlin Heidelberg.
