Semi-automatic Integration of Learned Ontologies into a Collaborative Framework
(2007)The paper presents a novel ontology lifecycle scenario that explicitly takes the dynamics and data-intensiveness of real world applications into account. Changing and growing knowledge is handled by semi-automatic ... -
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 ... -
Towards Fine-grained Service Matchmaking by Using Concept Similarity
(2007)Several description frameworks to semantically describe and match services on the one hand and service requests on the other have been presented in the literature. Many of the current proposals for defining notions of ... -
dlvhex-sparql: A SPARQL-compliant query engine based on dlvhex
(CEUR, 2007)This paper describes the dlvhex SPARQL plugin, a query processor for the upcoming Semantic Web query language standard by W3C. We report on the implementation of this languages using dlvhex, a flexible plugin system ... -
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 ... -
A lookup index for Semantic Web resources
(2007)Developers of Semantic Web applications face a challenge with respect to the decentralised publication model: where to find statements about encountered resources. The ¿linked data¿ approach, which mandates that resource ... -
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 ... -
Dynamic Integration of Medical Ontologies in Large Scale
(ACM Press, 2007) -
Using Tags and Clustering to Identify Topic-Relevant Blogs
(IAAA, 2007)The Web has experienced an exponential growth in the use of weblogs or blogs. Blog entries are generally organised using tags, informally defined labels which are increasingly being proposed as a `grassroots¿ answer to ... -
Collaboration on the Social Semantic Desktop
(2007)To accomplish the daily work people use several desktop applications to collaborate with co-workers. Each application is specialized on a specific domain, such as document management, email, or time planning. Although the ... -
Infrastructure for data processing in large-scale interconnected sensor network
(2007)With the price of wireless sensor technologies diminishing rapidly we can expect large numbers of autonomous sensor networks being deployed in the near future. These sensor networks will typically not remain isolated but ... -
WSMO-PA: Formal Specification of Public Administration Service Model on Semantic Web Service Ontology
(IEEE, 2007)In this paper we define a formal model for a Public Ad- ministration service on the basis of the Web Service Modeling Ontology (WSMO). For this purpose we employ the generic public service object model of the Governance ... -
Dynamic Service Discovery through Meta-Interactions with Service Providers
(Springer, 2007)Dynamic discovery based on semantic description of services is an essential aspect of the Semantic Web services integration process. Since not all data required for service discovery can always be included in service ... -
YARS2: A Federated Repository for Querying Graph Structured Data from the Web
(2007)We present the architecture of an end-to-end semantic search engine that uses a graph data model to enable interactive query answering over structured and interlinked data collected from many disparate sources on the Web. ... -
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 ... -
JeromeDL - a Semantic Digital Library
(2007)JeromeDL is a Semantic Digital Library engine. It uses SemanticWeb and Social Networking technologies to improve browsing and searching for resources. With JeromeDL¿s social and semantic services every library user ... -
Leveraging existing web frameworks for a SIOC explorer to browse online social communities
(2007)Since online SemanticWeb applications are based on existing Web infrastructure, developing these applications could leverage experiences with and infrastructure of existing frameworks. These frameworks need to be extended ... -
Knowledge Sharing and Filtering on Semantic Web 2.0
(2007)E-learning and other popular services that grow on the fertile soil of the Internet technologies usually fail to reach their full potential. With new, emerging technologies of the second generation Internet there is even ... -
Who the FOAF knows Alice? A needed step towards Semantic Web Pipes
(2007)In this paper we take a view from the bottom to RDF(S) reasoning. We discuss some issues and requirements on reasoning towards effectively building SemanticWeb Pipes, aggregating RDF data from various distributed sources. ... -
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 ...
