Workflow design, mashup configuration, and composite
service formation are examples where the capabilities of
multiple simple services combined achieve a complex functionality.
In this paper we address the problem of limiting the number
of required services that fulfill the required capabilities while
exploiting the functional specialization of individual services.
Our approach strikes a balance between finding one service
that matches all required capabilities and having one service for
each required capability. Specifically, we introduce a weighted
fuzzy clustering algorithm that detects implicit service capability
groups. The clustering algorithm considers capability importance
and service fitness to support those capabilities. Evaluation based
on a real world dataset successfully demonstrates the effectiveness
and applicability for service aggregation.
