Following closely on the heels of the recent release of Pellet 1.5.2, we’ve updated OwlSight. Since OwlSight runs on raw Pellet power, the new version, .52, updates the back-end to take advantage of the recent Pellet release.

If you have not already taken a look at OwlSight, cruise on over to the OwlSight page and take it for a spin. For those not already in the know, OwlSight is a lightweight browser-based ontology browser utilizing both GWT (and GWT-Ext) and Pellet as its core technologies. Until next time, stay classy cyberspace.

Following Monday’s announcement of the release of OwlSight .50, we’re pleased to announce another update to OwlSight, version .51. This is a minor bug fix release and no new functionality was added. Thanks to those users who took the time to report issues:

• URL escaping of parameters passed into OwlSight
• Rendering of datatype values for Individuals has been fixed
• If an error occurs while generating an explanation, control is properly returned to the main application window.

As Kendall suggested in a previous blog, I was doing some hacking on OwlSight last week, and well, for the last several weeks really. I’ve had some free time on my hands ever since we released POPS and I’ve been spending it with my new baby, and everyone’s favorite in-browser ontology viewer, OwlSight. About three weeks ago, we released a major update; the big news was that we now supported the newly released Pronto and I had recoded pretty much the entire interface using Gwt-Ext.

In the weeks since that announcement, I’ve gone on to further extend the functionality of OwlSight. The main items of interest are:

• Support for viewing annotations
• Support for Individuals
• GRDDL based ontology repository support
• Enhanced the Property view, adding domains, ranges and inverse property information
• Storage of your ontology repository in a browser cookie so its loaded each time you run OwlSight
• Improved explanation rendering
• OwlSight handles URL parameters; links to ontologies or repositories can be passed in and loaded on startup.

You can find some more details information about our ontology repository work here and there is now a very simple, and probably incomplete, OwlSight readme.

Make your own ontology repository. Link to OwlSight from your web pages, and use it to show off your favorite ontologies. Until next time, stay classy Cyberspace.

Fresh on the heels of our recent announcement of the first release of Pronto, we’re happy to announce release of a new version of OwlSight, which includes support for Pronto and browsing probabilistic ontologies and explanations for probabilistic inferences.

In addition to including support for probabilistic ontologies, the new version of also has an entirely new look and feel. We used GWT-Ext to build the new UI components, with very pleasing results. We’ve also fixed a number of bugs, and made some other modest improvements. But if you are interested in Pronto, or you are just interested in a lightweight, browser-based ontology browser, you should give the latest version of OwlSight a try.

To get started, there are two new bookmarks included with OwlSight, both of which illustrate probabilistic reasoning in the context of OWL DL reasoning. Choose the Penguin Bird or BRC bookmarks to load and browse a probabilistic ontology.
