  • Approximating Query Completeness by Predicting the Number of Answers in DHT-based Web Applications 

    Karnstedt, Marcel; Hauswirth, Manfred; Sapkota, Brahmananda (2008)
  • A Context Lifecycle For Web-Based Context Management Services 

    Hynes, Gearoid; Reynolds, Vinny; Hauswirth, Manfred (2009)
    During the development of context aware applications a con- text management component must traditionally be created. This task re- quires specialist context lifecycle management expertise and hence can be a significant ...
  • Cost-Aware Processing of Similarity Queries in Structured Overlays 

    Karnstedt, Marcel; Hauswirth, Manfred (2006)
    Large-scale distributed data management with P2P systems requires the existence of similarity operators for queries as we cannot assume that all users will agree on exactly the same schema and value representations and ...
  • Data availability analysis in P2P networks 

    Sanaullah, Nazir (2012-09-28)
    P2P network architectures have gained popularity as applications for sharing files between users. A P2P network provides a scalable, robust, and economical storage architecture. These features have led to the extended ...
  • DAW: Duplicate-AWare Federated Query Processing over the Web of Data 

    Parreira, Josiane Xavier; Deus, Helena F.; Hauswirth, Manfred (Springer, 2013)
    Over the last years the Web of Data has developed into a large compendium of interlinked data sets from multiple domains. Due to the decentralised architecture of this compendium, several of these datasets contain duplicated ...
  • Demo: Visual Programming for the Semantic Desktop with Konduit 

    Möller, Knud; Handschuh, Siegfried; Decker, Stefan (2008)
    In this demo description, we present Konduit, a desktop-based platform for visual programming with RDF data. Based on the idea of the semantic desktop, non-technical users can create, manipulate and mash-up RDF data with ...
  • Discovery of Optimized Web Service Configurations Using a Hybrid Semantic and Statistical Approach 

    Zaremba, Maciej; Migdal, Jacek; Hauswirth, Manfred (IEEE, 2009)
    We present a Semantic Optimized Service Discovery (Se- mOSD) approach capable of handling Web service search requests on a fine-grained level of detail where we augment semantic service descriptions with statistically built ...
  • A Formal Investigation of Semantic Interoperability of HCLS Systems 

    Sahay. Ratnesh; Zimmermann, Antoine; Fox, Ronan; Polleres, Axel; Hauswirth, Manfred (IGI Global, 2013-06)
    Semantic interoperability facilitates Health Care and Life Sciences (HCLS) systems in connecting stakeholders at various levels as well as ensuring seamless use of healthcare resources. Their scope ranges from local to ...
  • Geographic Routing in Wireless Multimedia Sensor Networks 

    Shu, Lei; Hauswirth, Manfred (IEEE, 2008)
    In this paper, a -Phase geographic GreeTwody Forwarding (TPGF) routing algorithm is proposed in wireless multimedia sensor networks (WMSNs). TPGF is a pure geographic greedy forwarding routing algorithm, which does not ...
  • Infrastructure for data processing in large-scale interconnected sensor network 

    Aberer, Karl; Hauswirth, Manfred (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 ...
  • An Infrastructure for Privacy-Enabled Sharing of Context Data 

    Hynes, Gearoid (2011-08-29)
    The concept of context originated in the ubiquitous computing domain where information regarding the user's situation was gathered using sensing devices, allowing the application to automatically adapt according to the ...
  • Integrating Social Networks and Sensor Networks 

    Breslin, John; Decker, Stefan; Hauswirth, Manfred; Hynes, Gearoid; Phuoc, Danh Le; Passant, Alexandre; Polleres, Axel; Rabsch, Cornelius; Reynolds, Vinny (2009)
  • Linked Open Data in Sensor Data Mashups 

    Phuoc, Danh Le; Hauswirth, Manfred (CEUR, 2009)
    Sensors and the real-time data they produce are novel sources of information which need to be integrated into the Semantic Web at very large scale. Most of the time such data is locked inside specific applications and only ...
  • Middleware support for the "Internet of Things" 

    Aberer, Karl; Hauswirth, Manfred (2006)
    The `Internet of Things¿ intends to enhance items of our everyday life with information and/or processing and interconnect them, so that computers can sense, integrate, present, and react on all kinds of aspects of the ...
  • Multi-priority Multi-path Selection for Video Streaming in Wireless Multimedia Sensor Networks 

    Zhang, Lin; Hauswirth, Manfred; Shu, Lei; Zhou, ZhangBing; Reynolds, Vinny (Springer, 2008)
    Video sensors are used in wireless multimedia sensor networks (WMSNs) to enhance the capability for event description. Due to the limited transmission capacity of sensor nodes, a single path often cannot meet the ...
  • A Native and Adaptive Approach for Linked Stream Data Processing 

    Le Phuoc, Danh (2013-04-08)
    Sensors, mobile devices and social platforms generate an immense amount of stream data in various formats and schemata. For these areas, the idea of Linked Stream Data is to extend RDF data model to cope with the heterogeneity ...
  • NetTopo: Beyond Simulator and Visualizer for Wireless Sensor Networks 

    Shu, Lei; Wu, Chun; Hauswirth, Manfred (IEEE and LNCS, 2008)
    Deploying real WSN testbed provides a realistic testing environment, and allows users to get more accurate test results. However, deploying real testbed is highly constrained by the available budget when the test needs ...
