Abstract
We present an intelligent service matchmaker, called iSeM, for adaptive and hybrid semantic service selection that exploits the full semantic profile in terms of signature annotations
in description logic SH and functional specifications in SWRL. In particular, iSeM complements its strict logical signature matching with approximated reasoning based on logical concept abduction
and contraction together with information-theoretic similarity and evidential coherence-based valuation of the result, and nonlogic- based approximated matching. Besides, it may avoid failures
of signature matching only through logical specification plugin matching of service preconditions and effects. Eventually, it learns the optimal aggregation of its logical and non-logic-based
matching filters off-line by means of binary SVM-based service relevance classifier with ranking. We demonstrate the usefulness of iSeM by example and preliminary results of experimental
performance evaluation.
