Association rule based situation awareness in web-based environmental monitoring systems

The Tasmanian ICT of CSIRO developed a Sensor Web test-bed sys- tem for the Australian water domain. This system provides an open platform to access and integrate near real time water information from distributed sensor networks. Traditional hydrological models can be adopted to analyze the data on the Sensor Web system. However, the requirements on high data quality and high level domain knowledge may greatly limit the application of these models. To overcome some these limitations, this paper proposes a data mining ap- proach to analyze patterns and relationships among different hydrological events. This approach provides a flexible way to make use of data on the Hy- drological Sensor Web.
