Since the 1980s, software agents and multi-agent systems have grown into what is now one of the most active areas of research and development activity in computing generally. One of the most important reasons for the current intensity of interest in the agent-based computing paradigm certainly is that the concept of an agent as an autonomous system, capable of interacting with other agents in order to satisfy its design objectives, is a natural one for software designers. This recognition has led to the growth of interest in agents as a new paradigm for software engineering.This book reflects the state of the art in the field by presenting 14 revised full papers accepted for the second workshop on this topic, AOSE 2001, together with five invited survey articles. The book offers topical sections on societies and organizations, protocols and interaction frameworks, UML and agent systems, agent-oriented requirements capture and specification, and analysis and design.
