Exploring OLAP Data with Parallel Dimension Viewss a range of exploration tasks including viewing data distribution, comparing data distributions and viewing correlation. The main benefit of our interface is its support for rapid and flexible overviews across many dimensions and multiple hierarchy levels at the cost of less detailed views.

Understanding User Behavior through Summarization of Window Transition Logs1) task summarization by HMM; (2) user behavior comparison by kernel principle component analysis based on a graph kernel. The experimental results show that our method reveals implicit user behavior at a high level of abstraction, and allows us to understand individual user behavior among groups, and over time.

Information Filtering by Using Materialized Skyline Viewl databases, skyline on spatial databases, and skyline set. We materialize such skyline information to make concise answer for each query. We also considered methods for maintaining materialized skyline view up to date to handle an update for a numerical database.
