1. A method for constructing a processing request so that an information processing application satisfying the processing request can be assembled, comprising: inputting a processing request, wherein the processing request includes a goal that is represented by a graph pattern that semantically describes a desired processing outcome, and assembling a processing graph that includes at least one component that satisfies the desired processing outcome, wherein the processing graph is assembled by associating the graph pattern that semantically describes the desired processing outcome with a graph pattern that semantically describes an applicability condition of the at least one component, wherein the association between the graph pattern that semantically describes the desired processing outcome and the graph pattern that semantically describes an applicability condition of the at least one component is based on a determination, which is performed during the assembly of the processing graph, that the at least one component is permitted to receive data produced by part of the processing graph as input, wherein the processing request further includes a constraint that is represented by a graph pattern that semantically describes constraints on the components to be used in the assembly of the processing graph and the determination that the at least one component is permitted to receive data produced by part of the processing graph as input is made in response to the applicability condition of the at least one component satisfying the constraints, and wherein the method is performed using a processor; wherein the method further comprises: deploying an information processing application embodying the at least one component of the processing graph; and operating the information processing application; wherein result data is produced when operating the information processing application; wherein when the goal is a goal that requests the production of data, the result data includes an element that is a requested data item.
