UML statecharts are a widely accepted standard for modeling software behavior. But, despite the increasing importance of semantics for software behavior, semantics has been treated within UML as mere reasoning add-ons. We propose fully integration of UML statecharts with behavioral knowledge obtained from novel behavioral ontologies into a Unified Software-Knowledge model. These unified models have two important characteristics: first, misbehaviors are explicitly represented; second, behavioral ontologies generate graphs isomorphic to UML statecharts, by construction. This approach is applicable to run time measurements, to check the actual software behavior correctness and efficiency. Measurement discrepancies may trigger knowledge discovery mechanisms to update the unified models. The approach is illustrated with statechart examples from the domain of GOF software design patterns.
