    • Aggregate Sharing in Stream Databases 

      Wang, Lidan; Freschl, Jeffrey (University of Wisconsin-Madison Department of Computer Sciences, 2005)
      We consider the problem of handling aggregate computations in a scalable fashion in stream databases. The queries of interest are sliding-window aggregate queries over a single data stream. In the na�ve approach for this ...
    • Badger: An Entropy-Based Web Search Clustering System with Randomization and Voting 

      Wang, Lidan; Schulze, Chloe Whyte (University of Wisconsin-Madison Department of Computer Sciences, 2005)
      We have implemented and improved an entropy-based clustering algorithm. In addition to utilizing entropy as a clustering mechanism, our algorithm, Badger, uses randomization and a voting scheme to improve the quality of ...
