We discussed a new approach using inference fusion, i.e. the cooperative reasoning from distributed heterogeneous inference systems, to extend the expressive and deductive powers of existing Description Logic (DL) based systems. More specifically, our approach integrates results from a DL reasoner with results from a constraint solver. Inference fusion (i) fragments heterogeneous input knowledge to generate suitable homogeneous inputs for the DL and constraint reasoners; (ii) passes control to each reasoner, retrieving the results and making them available to the other reasoner for further inferencing; and (iii) dynamically combines the results of the two reasoners to present the overall conclusion. We also outline the main features of inference fusion by way of a small example.
