Many systems have been built for vertex-centric parallel graph processing. Based on the Bulk Synchronous Parallel (BSP) model, they execute user-defined operations at vertices iteratively and exchange information between vertices by messages. Even though the native BSP systems (e.g. Pregel and Giraph) execute the operations on vertices synchronously within an iteration, many other platforms (e.g....
When faced with dirty data fused from different sources, modern data management generally trace origins using data provenance technical to repair it fundamentally. Unfortunately, the state-of-art data provenance approaches can only deal with small amount of data using annotation or inverse process. What's worse, these approaches just work under stand-alone mode, resulting in low efficiencies. In this...
Radio frequency identification (RFID) has been widely deployed to track product flow in such fields as automated manufacture, retail and supply chain management. The special characteristics of streaming RFID data, combined with the specific scenarios of RFID applications, present numerous challenges in RFID stream processing, including noisy and incomplete data, temporal and spatial correlations and...
