static dynamic

Developer-centric

User-centric

Traditional SE

New SE Paradigm

September 2014


Main Approaches

User-centric Service Engineering Enable high-level software design (in multiple

abstractions) with primarily considering user tasks

Support iterative and gradual development Improve reusability Enable application adaptability

Semantic Web Enabled Software Engineering Improve correctness and context awareness Improve interoperability

End-user Software Engineering Support semi-automatic composition Enable visual programming (mash-ups)
