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 ... -
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 ... -
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 ... -
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 ... -
Ontologising Interaction Behavior for Service-Oriented Enterprise Healthcare Integration
Sahay, Ratnesh; Fox, Ronan; Hauswirth, Manfred (IEEE, 2008) -
PPEPR for Enterprise Healthcare Integration
Fox, Ronan; Sahay, Ratnesh; Hauswirth, Manfred (Springer, 2008)PPEPR is software to connect healthcare enterprises. Healthcare is a complex domain and any integration system that connects healthcare enterprise applications must facilitate heterogeneous healthcare systems at all levels ... -
Process Mediation Based on Triple Space Computing
Zhou, ZhangBing; Sapkota, Brahmananda; Cimpian, Emilia; Foxvog, Doug; Vasiliu, Laurentiu; Hauswirth, Manfred (Springer, 2008)Web services are inherently heterogeneous at both data and behavioral levels because of the nature of the Web, which is the main obstacle to the usability of Web services. The heterogeneity at a behavioral level is generally ... -
A Scenario-View Based Approach to Analyze External Behavior of Web Services for Supporting Mediated Service Interactions
Zhou, ZhangBing; Bhiri, Sami; Shu, Lei; Vasiliu, Laurentiu; Hauswirth, Manfred (IEEE, 2008)Web service interactions have triggered the initiative to identify and solve mismatches from a behavioral aspect. Current approaches are limited since they mainly focus on control-flow but largely ignore data-flow. In this ... -
Semantic Service-Oriented Design And Development Methodology For Enterprise Healthcare Integration
Sahay, Ratnesh; Fox, Ronan; Hauswirth, Manfred (WEBIST, 2009-03-23)The application of ontologies (semantic) to enhance any existing or proposed Service-Oriented Architecture (SOA) based software architecture has various levels of use in terms of intra and inter enterprise integration. The ... -
