Building a Semantic Web Search Engine: Challenges and Solutions
(2008)
Current web search engines return links to documents for user-specified keywords queries. Users have to then manually trawl through lists of links and glean the required information from documents. In contrast, semantic ...
Performing Object Consolidation on the Semantic Web Data Graph
(2007)
An important aspect of Semantic Web technologies is the
issue of identity and uniquely identifying resources, which
is essential for integrating data across sources. Currently,
there is poor agreement on the use of ...
ReConRank: A Scalable Ranking Method for Semantic Web Data with Context
(2006)
We present an approach that adapts the well-known PageRank/HITS algorithms to Semantic Web data. Our method combines ranks from the RDF graph with ranks from the context graph, i.e. data sources and their linkage. We present ...
Towards a social provenance model for the Web
(2007)
In this position paper we firstly present the established notion of provenance on the Semantic Web (also referred to as named graphs or contexts), and secondly argue for the benefit of adding to the pure technical notion ...
Podcast Pinpointer: A Multimedia Semantic Web Application
(IEEE, 2005)
In late 2004, a new method of publishing multimedia broadcasts on the Internet became popular called `Podcasting¿. Podcasting incorporates existing feed description formats, namely RSS 2.0, to ...
Scalable Authoritative OWL Reasoning on a Billion Triples
(2008)
In this paper we present a scalable algorithm for performing a subset of OWL reasoning over web data using a rule-based approach to forward-chaining; in particular, we identify the problem of ontology hijacking: new ...
An Empirical Investigation of Networks in the Blogosphere
(2007)
We seek out to investigate the social networks manifested in weblogs. Our dataset, derived from an initial list of URIs, consists of 3.9M files in XML or RDF format, totaling over 400M statements in RDF. We continue ...
An Interactive Map of Semantic Web Ontology Usage
(IEEE, 2008)
Publishing information on the Semantic Web using common formats enables data to be linked together, integrated and reused. In order to fully leverage the potential for interlinking data by reusing existing schemas, an ...
