The ROLE SRE Approach – Getting More Concrete

Dominik RenzelChair of Computer Science 5,

RWTH Aachen University, Germany

WP1 WorkshopMay 14, 2010 - Leicester, UK

The ROLE SRE Approach – Support for the Long Tail

• No Mainstream Web 2.0 Requirements Engineering!• “Overall Top-N“: naive approach• Needs of specialized CoPs neglected• Innovation Killer (clones only)

• Rather Long-Tail Requirements Engineering• “Community-Aware Top-N“• Special support for niche CoPs• High specialization, but high innovation

Explicit vs. Implicit Requirements

• Explicit Requirements• Actively stated by ROLE CoP members (usr, dev, res)• Requires communication between users & developers• Requires tools for active collection of requirements

• Implicit Requirements• Not directly stated by ROLE CoP members• Requires minable data (+technical means for acquisition)

• System usage monitoring

• User interaction monitoring

• Collaboratively generated content

• Requires requirements mining techniques
