Social Web

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

New Trends

• Web as a Platform• Mobile Web & “The One Web”• Internet of Things

– A network of objects• Internet of Services

– Locating and Accessing Services– Service Mash-up– Semantic Web Services

• Urban Computing• Web 3.0

– Future Internet with its three central pillars "Social Web", "Semantic Web" and "Service Web" [Christoph Meinel]


Paradigm Shift in Software Devel-opment


static dynamic

Developer-centric

User-centric

Traditional SE

New SE Paradigm

Main Approaches

• Task-oriented Service Computing– Enable high-level software design (in multiple

abstractions) with primarily considering user tasks– Support iterative and gradual development– Improve reusability– Enable application adaptability– Enable service-privacy tradeoff

• Dynamic & Adaptive Software Engineering– Improve correctness and context awareness– Improve interoperability– Support semi-automatic composition– Enable end-user programming (mash-ups)


Research Projects• Spontaneous Service Provision in IoT

Environments (미래부 )

• Dynamic and Distributed Service Discovery & Composition in Tactical Edge Environments (ADD)

• Cloud and Fog Based Service Computing for Distributed Super Computing Environments (미래부 )

• Component Grid: A Knowledge-based Software Reuse Environment (DAPA/ADD)

• Semantic-Cloud-based Content Recommendations (KT)

• Service-oriented Common Operation Environment for Unmanned Weapon Systems (Samsung Thales)


Spontaneous Service Provision in IoT Env.• Role-based proactive service provision• On-demand service requirements identification and composition• Service reconfiguration and optimization based on cognitive resources
