Service-Oriented Architecture (SOA) can provide a paradigm
for constructing context-aware collaboration systems. Particularly, the
promise of inexpensive context-aware collaboration devices and context-
awareness for supporting the selection of suitable services at run-time
have provoked growing adoptation of SOA in collaborative systems. In
this paper, we introduce an approach for selecting the most suitable ser-
vice within a SOA based collaboration system, where suitability depends
on the user's context. The approach includes context modelling, gener-
ation of context-aware selection criteria and a suitable service selection
methodology.
