CS AKTiveSpace: Building a Semantic Web Application [chapter]

Hugh Glaser, Harith Alani, Les Carr, Sam Chapman, Fabio Ciravegna, Alexiei Dingli, Nicholas Gibbins, Stephen Harris, m. c. schraefel, Nigel Shadbolt
2004 Lecture Notes in Computer Science  
In this paper we reflect on the lessons learned from deploying the award winning [1] Semantic Web application, CS AKTiveSpace.  ...  We consider next steps for the application, based on these lessons, and propose a strategy for expanding and improving the services afforded by the application.  ...  Harvesting To be convincing, the building of a Semantic Web application requires data on a large scale.  ...

RDF-3X

Thomas Neumann, Gerhard Weikum
2008 Proceedings of the VLDB Endowment  
RDF is a data representation format for schema-free structured information that is gaining momentum in the context of Semantic-Web corpora, life sciences, and also Web 2.0 platforms.  ...  Managing large-scale RDF data includes technical challenges for the storage layout, indexing, and query processing:  ...  This is done for each of the three possible pairs out of a triple and in each collation order (SP, PS, SO, OS, PO, OP), thus adding another six indexes.  ...

Improving life sciences information retrieval using semantic web technology

D. Quan
2007 Briefings in Bioinformatics  
This article gives an overview of the principles underlying a Semantic Web-enabled information retrieval system: creating a unified abstraction for knowledge using the RDF semantic network model; designing  ...  The Semantic Web community has made great strides in proposing solutions to these problems, and many efforts are underway to apply Semantic Web techniques to the problem of information retrieval in the  ...  A more task-centric approach to information retrieval is required in order for our ability to consume information on the Web to scale with the growth of the Web itself.  ...

CS AKTive space

m. c. schraefel, Nigel R. Shadbolt, Nicholas Gibbins, Stephen Harris, Hugh Glaser
2004 Proceedings of the 13th conference on World Wide Web - WWW '04  
This work illustrates a number of substantial challenges for the Semantic Web. These include problems of referential integrity, tractable inference and interaction support.  ...  The content is mediated through an ontology constructed for the application domain and incorporates components from other published ontologies.  ...  This application which won the 2003 Semantic Web Challenge [1] , illustrates a number of substantial issues for the Semantic Web.  ...

Approaches to visualising Linked Data: A survey

Aba-Sah Dadzie, Matthew Rowe
2011 Semantic Web Journal  
In this paper we describe key requirements which the visualisation of linked data must fulfil in order to lower the technical barrier and make the Web of Data accessible for all.  ...  The uptake and consumption of Linked Data is currently restricted almost entirely to the Semantic Web community.  ...  In order to justify the effort required to develop more effective means for consuming linked data we must first look at the merits the Web of Data provides over other existing large-scale data sets.  ...

People, Projects, Organizations, and Products: Designing a Knowledge Graph to Support Multi-Stakeholder Environmental Planning and Design

Sean N. Gordon, Philip J. Murphy, John A. Gallo, Patrick Huber, Allan Hollander, Ann Edwards, Piotr Jankowski
2021 ISPRS International Journal of Geo-Information  
As the need for more broad-scale solutions to environmental problems is increasingly recognized, traditional hierarchical, government-led models of coordination are being supplemented by or transformed  ...  These same barriers are more acute for geospatial data, which also faces the added challenge of maintaining and synchronizing both semantic and traditional geospatial datastores.  ...  Acknowledgments: We wish to thank Naicong Li, Steve Paplanus and Yuanyuan Tian for help with development and testing of the PPOp ontology.  ...

Heuristics-based query optimisation for SPARQL

Petros Tsialiamanis, Lefteris Sidirourgos, Irini Fundulaki, Vassilis Christophides, Peter Boncz
2012 Proceedings of the 15th International Conference on Extending Database Technology - EDBT '12  
One practical reason for this is that statistics typically are missing in web scale setting such as the Linked Open Datasets (LOD).  ...  Query optimization in RDF Stores is a challenging problem as SPARQL queries typically contain many more joins than equivalent relational plans, and hence lead to a large join order search space.  ...  for large scale and evolving RDF datasets.  ...
