The refraction count RC(PS) relies on the Semantic Summary, which in turn relies on the ROCs. The S-Match(property,keyword) metric relies on a property hierarchy. The final SEMRANK metric involves a (modulated) composition of five terms, four of which rely on a schema to be defined. # Is this reliance a strength or a weakness? # How do the metrics change as the presence, completeness, and quality of the schema changes?
