Syndication on the Web using a description logic approach

Autor: Vladimir Kolovski, Christian Halaschek-Wiener

Publikováno v: Journal of Web Semantics. 6:171-190

Syndication systems on the Web have attracted vast amounts of attention in recent years. As technologies have emerged and matured, there has been a transition to more expressive syndication approaches; that is, subscribers and publishers are provided

Optimizing Enterprise-Scale OWL 2 RL Reasoning in a Relational Database System

Autor: Vladimir Kolovski, Zhe Wu, George Eadon

Publikováno v: Lecture Notes in Computer Science ISBN: 9783642177453
International Semantic Web Conference (1)

OWL 2 RL was standardized as a less expressive but scalable subset of OWL 2 that allows a forward-chaining implementation. However, building an enterprise-scale forward-chaining based inference engine that can 1) take advantage of modern multi-core c

Visualizing large-scale RDF data using Subsets, Summaries, and Sampling in Oracle

Autor: Vladimir Kolovski, Eugene Inseok Chong, Seema Sundara, Medha Atre, Souripriya Das, Zhe Wu, Jagannathan Srinivasan

Publikováno v: ICDE

The paper addresses the problem of visualizing large scale RDF data via a 3-S approach, namely, by using, 1) Subsets: to present only relevant data for visualisation; both static and dynamic subsets can be specified, 2) Summaries: to capture the esse

Implementing an Inference Engine for RDFS/OWL Constructs and User-Defined Rules in Oracle

Autor: Souripriya Das, Zhe Wu, Jagannathan Srinivasan, Vladimir Kolovski, Eugene Inseok Chong, M. Annamalai, George Eadon

Publikováno v: ICDE

This inference engines are an integral part of semantic data stores. In this paper, we describe our experience of implementing a scalable inference engine for Oracle semantic data store. This inference engine computes production rule based entailment

Analyzing web access control policies

Autor: James A. Hendler, Vladimir Kolovski, Bijan Parsia

Publikováno v: WWW

XACML has emerged as a popular access control language on the Web, but because of its rich expressiveness, it has proved difficult to analyze in an automated fashion. In this paper, we present a formalization of XACML using description logics (DL), w

Implementing OWL Defaults

Autor: Bijan Parsia, Vladimir Kolovski, Yarden Katz

Publikováno v: OWLED

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 often requested some form of non-monotonic reasoni

Integrating Datalog with OWL: Exploring the AL-log Approach

Autor: Edna Ruckhaus, Bernardo Cuenca, Vladimir Kolovski, Bijan Parsia

Publikováno v: Logic Programming ISBN: 9783540366355
ICLP

We present OWL-log, which is an implementation of the $\mathcal{AL}$-log hybrid knowledge representation system where the Description Logics component is extended to the Web Ontology Language OWL DL. We implemented an OWL-log reasoner coupled to the

An electronic learning assistant

Autor: Strahil Jordanov, Vladimir Kolovski, John Galletly

Publikováno v: Proceedings of the 5th international conference on Computer systems and technologies - CompSysTech '04.

In this paper, based on our previous work, we describe the functionality and implementation of a Semantic Web-based e-learning application - an Electronic Learning Assistant (ELA) - with focus on the RDF data model and OWL ontology of the application
