Towards a Nonmonotonic Extension to OWL (2009)
Abstract. We discuss ALCK, a nonmontonic logic that augments ALC with the epistemic operator K, and argue that a similar extension to OWL would be desirable. We show, however, that at its current...

Prioritized Default Logic with Trust Values (2008)
A drawback of traditional default logic is that there is no general mechanism for preferring one default rule over another. To remedy this problem, numerous default logics augmented with priority...
The Use of Lisp in Semantic Web Applications (2008)
The Semantic Web adds a layer of logic and metadata to the current World Wide Web. By utilizing traditional Artifical Intelligence (AI) and Knowledge Representation (KR) techniques for both the...

Jennifer Golbeck, Yarden Katz, Daniel Krech, Aaron Mannes, Taowei David, Wang James Hendler
Abstract. PaperPuppy is a system designed to allow the exploration and analysis of a network of ISWC conference authors and publications. Using proceeding data from the first four ISWC conferences,...
ABSTRACT Nonmonotonic Reasoning With Web-Based Social Networks (2008)
A drawback of traditional default logic is that there is no general mechanism for preferring one default rule over another. To remedy this problem, numerous default logics augmented with priority...
Evren Sirin, Bijan Parsia, Bernardo Cuenca Grau, Aditya Kalyanpur, Yarden Katz
In this paper, we present a brief overview of Pellet: a complete OWL-DL reasoner with acceptable to very good performance, extensive middleware, and a number of unique features. Pellet is the first...
Representing Web Service Policies in OWL-DL (2006)
Kolovski, Vladimir, Parsia, Bijan, Katz, Yarden, Hendler, James
Recently, there have been a number of proposals for languages for expressing web service constraints and capabilities, with WS-Policy and WSPL leading the way. The proposed languages, although...

Semantic Web Research Trends and Directions (2006)
Golbeck, Jennifer, Cuenca Gran, Bernardo, Halaschek-Wiener, Christian, Kalyanpur, Aditya, Katz, Yarden, Parsia, Bijan, ...
The Semantic Web is not a single technology, but rather a collection of technologies designed to work together. As a result, research on the Semantic Web intends both to advance individual...
Implementing OWL Defaults (2006)
Kolovski, Vladimir, Parsia, Bijan, Katz, Yarden
While it has been argued that knowledge representation for the World Wide Web must respect the open world assumption due to the "open" nature of the Web, users of the Web Ontology Language (OWL) have...

Belief Base Revision For Expressive Description Logics (2006)
Christian Halaschek-wiener, Yarden Katz, Bijan Parsia
Abstract. In this work, we address the problem of revision of OWL-DL knowledge bases. We focus on belief bases revision as it has previously been shown that OWL-DL is not AGM-compliant for revision....
Social network-based trust in prioritized default logic (2006)
A drawback of traditional default logic is that there is no general mechanism for preferring one default rule over another. To remedy this problem, numerous default logics augmented with priority...
