Threshold Interval Indexing for Complicated Uncertain Data

  title={Threshold Interval Indexing for Complicated Uncertain Data},
  author={Andrew Knight and Manjeet Rege},
Uncertain data is an increasingly prevalent topic in database research, given the advance of instruments which inherently generate uncertainty in their data. In particular, the problem of indexing uncertain data for range queries has received considerable attention. To efficiently process range queries, existing approaches mainly focus on reducing the number of disk I/Os. However, due to the inherent complexity of uncertain data, processing a range query may involve high computational cost in… CONTINUE READING
