11. A system comprising: a first information system associated with a first ontology comprising a first representation of a common concept; a second information system associated with a second ontology comprising a second representation of the common concept, wherein the second representation is distinct from the first representation; a web service ontology describing concepts and relationships of an interface for a web service; a service agent configured to map concepts from the first ontology, the second ontology, a context ontology capturing the common concept, and the web service ontology to each other to create an augmented ontology; and a computing device configured to: search the augmented ontology for an execution path between an input to the first information system and a desired output from the second information system, the execution path traversing through concepts of the web service ontology, and generate executable code that accepts the input and invokes the execution path to produce the desired output.
