Distributed Semantic Sensor Networks

How to use semantics and knowledge distribution to integrate sensor data of disparate data sources

In this research project we focused on sensor networks and how semantic
web technologies and knowledge sharing can make integration
of distributed sensor data possible. To achieve this we have first
identified the main challenges to address to allow for data
integration. A distributed semantic sensor network framework is proposed
that uses semantic web techniques and knowledge sharing to
address these challenges. We propose that knowledge sharing in a sensor
network is a key aspect of data integration in a dynamic
environment, since it allows the network to handle changes in the
environment. This project is innovative in that it proposes new ways
to handle semantic integration in a distributed environment, by using
question federation and data conversion on semantically annotated data
and questions. It contributes to current research in that our framework
enables data integration of distributed sensor data.
