Fast and Scalable Pattern Mining for Media-Type Focused Crawling
(2009)
Search engines targeting content other than hypertext documents require a crawler that discovers resources identifying files of certain media types. Naive crawling approaches do not guarantee a sufficient supply of new ...
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 ...
SWSE: Objects before documents!
(2008)
Web search engines are immensely useful for locating documents online. However, with more and more structured data being published online, the restriction to the hyperdocument model impairs the usefulness for searching and ...
SWSE: Answers Before Links!
(CEUR-WS.org, 2007)
We present a system that improves on current document- centric Web search engine technology; adopting an entity-centric perspective, we are able to integrate data from both static and live sources into a coherent, interlinked ...
The ExpertFinder Corpus 2007 for the Benchmarking and Development of ExpertFinding Systems
(2007)
We provide a benchmark dataset for expert finding within the computer science domain. We show how large isolated data graphs from disparate structured data sources can be combined to form one, large, well-linked RDF graph ...
