19. A computer system for meeting an economic challenge, the system comprising: a reasoner processor operable for receiving a structured document having a field for an economic output, a nation of interest and starting conditions for the economic challenge; a library database operable with the reasoner processor to locate data and at least one model applicable to the challenge, wherein the reasoner processor develops a selected data set and develops at least one selected model of the specification using a forward and backward chaining reasoner process which draws from the at least one selected model and the selected data set to identify a solution to the challenge and tag the selected data set and the at least one selected model for providing information therefor; an execution engine operable with the reasoner processor to execute the at least one selected model using the selected data set for providing results data responsive to the field for an economic output, the nation of interest and the starting conditions for the challenge; and a visualization engine operable with the execution engine to represent the results data and relationships therebetween in a visualization ontology for the reasoner processor providing visual images of the results data resulting from the specification.
20. The system according to claim 19 , further comprising a first user interface operable with the reasoner processor to receive a specification of a challenge.
