Title:

Spatial Queries over Uncertain Data Streams

 

Abstract:

As the number of mobile and wearable devices dramatically increases recently, the amount of data acquired in the cloud applications with these devices becomes huge and creates new problems in big data. The derived data may be imprecise or uncertain due to the transmission loss or the error of the devices. In addition, the values of data vary as time evolves. Such data are referred to as uncertain data streams. With the demand of real-time process in big data, how to effectively manage, process, or analyze the data on uncertain data streams become crucial. In this talk, related topics about query processing for some important spatial query types over uncertain data streams will be introduced, including probabilistic k nearest neighbors search,probabilistic reverse k nearest neighbors search, and probabilistic skyline query. In particular, an effective approach for probabilistic skyline query over uncertain data streams will be discussed.
