Discovering Topical Structures of Databases

Summary: iDisc uses a multi-strategy learning approach over schemas and data to cluster tables by topic with representations and meta-clustering. Extensible, it adds aggregation, clusterer boosting, a table-importance measure, and representations for semantic browsing, with strong accuracy on databases.
