I don't see why you couldn't do this [I've used both systems]. Of course, it might be easier to open a connection to the OpenCyc reasoner and let it do any inferencing you are interested in, since it has specialists to do reasoning over certain parts of the KB much faster than logical inference. Some of the inferencing Cyc performs might be tedious at best to replicate in KW rules as well.
You could then use predicate attachment to get access to the cyc reasoning in KW. (i.e. defdetpred).

Hi, David
Recently I'm thinking about using KnowledgeWorks as a ontology platform,
by import all data from the OpenCyc[1] project, and write a simple
inference engine based on KW rules. Is it possible for KW?
Thanks.
