Any idea what algorithms are fast for this part of inferencing? I bet there's something generic (non-RDF) that's fast and crude. > Question: > What inference engine can be plugged into Jena smoothely? Offhand, I'm not sure, but there are lots of Prolog engines around for Java, and one or two Rete engines. Actually I'd be surprised if someone *hadn't* already got these plugged into Jena. Probably worth trying the Jena mailing list ;-) I don't know if anyone's tried this yet, but it should be possible to byte-compile Pychinko [1] for Java using Jython. Whether or not it would be possible to operate directly on Jena models or whether you'd need to serialize back and forth is another matter... But if you find a good algorithm for the specific operations you need you could always hard-wire it for performance. Cheers, Danny.
