Using OwlDlTrHReasoner

January 24, 2007 Leave a comment Go to comments

OwlDlTrHReasoner is a new OWL DL reasoning module added to Bossam, which shows much better performance than Bossam’s default OWL DL reasoning module. You can create an instance of OwlDlTrHReasoner by calling bossam.app.IReasoner.createOwlDlTrHReasoner().

In Bossam shell, instead of owl, use owltr as follows:

load owltr from http://www.w3.org/TR/2004/REC-owl-guide-20040210/wine;

Yeap. That’s it. OwlDlTrHReasoner completes a forward-chaining reasoning session over the W3C wine ontology in less than 3 seconds, on my 1.8Ghz Core Duo notebook with 128MB of Java heap memory. Not bad, right?

Doesn’t that reasoner lose too many derivations? Well, actually, I have to see from now on… 🙂 I’d be greatly appreciated for any feedback and problem reports on this new reasoner. 🙂
