Semantic Data Management (Dagstuhl Seminar 12171)

Authors: Grigoris Antoniou, Oscar Corcho, Karl Aberer, Elena Simperl, and Rudi Studer

Published in: Dagstuhl Reports, Volume 2, Issue 4 (2012)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 12171 "Semantic Data Management". The purpose of the seminar was to have a fruitful exchange of ideas between the semantic web, database systems and information retrieval communities, organised across four main themes: scalability, provenance, dynamicity and search. Relevant key questions cutting across all of these themes were: (i) how can existing DB and IR solutions be adapted to manage semantic data; and (ii) are there new challenges that arise for the DB and IR communities (i.e. are radically new techniques required)? The outcome was a deeper, more integrated understanding of the current state of the art on semantic data management and a the identification of a set of open challenges that will inform the three communities in this intersection.

10042 Abstracts Collection – Semantic Challenges in Sensor Networks

Authors: Karl Aberer, Avigdor Gal, Manfred Hauswirth, Kai-Uwe Sattler, and Amit P. Sheth

Published in: Dagstuhl Seminar Proceedings, Volume 10042, Semantic Challenges in Sensor Networks (2010)

Abstract
From 24.01. to 29.01.2010, the Dagstuhl Seminar 10042 ``Semantic Challenges in Sensor Networks '' was held in Schloss Dagstuhl~--~Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available.

10042 Executive Summary – Semantic Challenges in Sensor Networks

Authors: Karl Aberer, Avigdor Gal, Manfred Hauswirth, Kai-Uwe Sattler, and Amit P. Sheth

Published in: Dagstuhl Seminar Proceedings, Volume 10042, Semantic Challenges in Sensor Networks (2010)

Abstract
There has been significant progress in the number and capabilities of mobile devices, wireless sensors, and sensor networks. These developments, combined with the improved ability to bridge between the physical and cyber world in a more seamless way, have fostered the broad availability of sensor data capturing the state of the physical world. Promising and already successful examples are applications in environmental monitoring, agriculture, surveillance and intrusion detection, public security, and supply chain management. Furthermore, ideas towards a Web of sensors have been proposed, which is to be understood as a (large scale) network of spatially distributed sensors. In particular, terms like "Internet of Things", "Collaborating Objects" and "Ambient Intelligence" emphasize the trend towards a tighter connection between the cyber space and the physical world.
