Abstract. Healthcare decision making demands the systematic inte-
gration of knowledge from multiple sources, such as clinical guidelines,
clinical pathways, knowledge of practitioners and so on. We present a
semantic web based approach for synthesizing health knowledge through
the semantic modeling of healthcare knowledge as ontologies and reason-
ing over the ontologies to derive a morphed knowledge object. We demon-
strate the application of our approach by generating morphed knowledge
about prostate cancer clinical pathways.

Healthcare decision making during the diagnostic-treatment cycle is a com-
plex activity. Health professionals make clinical decisions by applying healthcare
knowledge that includes their experiential knowledge and explicit knowledge `ar-
tifacts', such as clinical practice guidelines, best evidence, clinical pathways and
so on [1]. One may note that each healthcare knowledge artifact captures specific
conceptual, contextual and operational aspects of a disease and corresponding
