Seen by many as the next revolution in software development for large, complex, distributed systems, agent systems represent one of the more exciting research areas in computer science. With the development of powerful personal devices, the vision of a personal agent now seems increasingly appealing too. It can even be claimed that intelligent software agents will eventually become an essential part of Web 4.0. Software agents are finding their way into areas such as environmental security, climate change, seismic safety, epidemic prevention, detection and response, computer emergency response.
