This post starts the series on the SPARQL-DL engine in Pellet…

In my previous post, I introduced Pronto, a probabilistic DL reasoning extension for Pellet…

This is the first in a series of posts on extending Pellet with probabilistic reasoning capabilities. We call this tool Pronto…

What could possibly be tricky about DL Safe SWRL rules? Well, the fact that I have to write out “DL Safe SWRL Rules” rather than merely “DL Safe Rules” or “SWRL Rules” should be some sort of indicator…

In the previous post, I gave a hint at the enormous power of (arbitrary) SWRL rules by showing how they can be used (directly and fairly easily) define various built in OWL constructs…

The OWL-using world wanted some sort of rules, and all the benefits they bring. SWRL is something of a de facto standard for extending OWL with rules with DL Safe SWRL rules (as I shall canonically call them) being the most commonly implemented variant…

Today we announced the release of OWLSight which is our new lightweight web-based ontology browser. OWLSight is a 100% Java application deployed as a webapp using the magic of the <a

Following 6 weeks after the release of 1.5-RC1, we’ve released Pellet 1.5.0. Notable changes since the 1.4 release series include incremental reasoning,

We’ve been collaborating with the National Cancer Institute this year to improve Pellet’s performance when working with the NCI

The first release candidate in the Pellet 1.5 series is available for download. Notable enhancements since the 1.4 release (in March) include significant optimizations within the concept classifier (which <a

We’ve been busy with new internal projects, as well as some milestones for some customer work

Pellet 1.4, final release, is now available for download…

Ah, my first ever blog entry. After years of flying under the radar, I am now bursting upon the blog “scene.” I have been an employee with C&P for 9 months now; previously to that, I worked with them as a

Our plan to offer commercial support for Pellet, and to gradually transition it from an academic to an industrial-strength tool, is proceeding nicely. OWL-DL is an interesting technology; but I keep hearing and seeing signs that the killer app still for Description Logics in Web technologies is still around the corner…
