Abstract: The unreliability of RFID data collection reduces the accuracy of data in RFID applications, further impacts on composite event detection. The existing algorithms which take primitive RFID readings as granularity can only reduce the occurrence frequency of collection mistake, and composite event detection hardly deal with those mistakes. In this paper, data are transformed from data level to logic area level as the interpolation granularity, the proposed constraint rules between composite events, and processing false detection. The reliability of the RFID data can be ensured by mining the correlation between the known composite events, judging the false detection of follow-up events, and considering the logical semantics of the specific application.
