17. The system of claim 16 , wherein when assembling each of the plurality of processing graphs the processor is further operative with the program to: match a post-inclusion state obtained after adding a first component to a processing graph to an applicability condition of a second component if the post-inclusion state obtained after adding the first component to the processing graph includes the objects that must be included in a pre-inclusion state applicable to the second component, and if the graph that semantically describes the objects in the post-inclusion state of the first component satisfies the graph pattern that semantically describes the objects that must be included in the pre-inclusion state applicable to the second component.
21. The system of claim 17 , wherein the processor is further operative with the program to: connect the first component to the second component when the post-inclusion state obtained after adding the first component to the processing graph and the applicability condition of the second component are matched to each other.
