1. A method for assembling processing graphs in an information processing system, comprising: performing, in an offline manner, translating a plurality of component descriptions into a planning language and performing reasoning on the plurality of component descriptions during the translation; and performing, in an online manner, receiving a processing request that specifies a desired processing outcome; translating the processing request into a planning goal; and assembling a plurality of processing graphs, each of the processing graphs including a plurality of the translated and reasoned components that satisfy the desired processing outcome, wherein each of the plurality of component descriptions includes: an applicability condition that includes variables representing objects that must be included in a pre-inclusion state, wherein the pre-inclusion state is a state against which the applicability of the component for inclusion in a processing graph is evaluated; and an inclusion effect that includes variables representing objects that must be included in a post-inclusion state, wherein the post-inclusion state is a state resulting from inclusion of the component in the processing graph, wherein every one of the variables in the inclusion effect must be included in the applicability condition, wherein each component creates at least one new object graph for each output.
