Social Web
Web resources are:
- Diverse
- Heterogeneous
- Dynamic
User-centric
integration
• Service-oriented
modeling
• Dynamic service
discovery
• Adaptive service
composition and
coordination
New Values

6. The Web: A Platform for Software Engineering
• Provides repositories for searching software services
• Provides a medium for deploying software as services
• Supports protocols to access software services
• Supports an environment to dynamically compose (assemble or synthesize)
applications

WE are working on software engineering issues of building software systems that
effectively utilize various Web-based resources, are adaptable to changing needs
and conditions in highly dynamic environments, and allow end users to participate
in the evolution of the software.
