Keyword searches are attractive because they facilitate users searching structured databases. On the other hand, tag clouds are popular for navigation and visualization purposes over unstructured data because they can highlight the most significant concepts and hidden relationships in the underlying content dynamically. In this paper, we propose coupling the flexibility of keyword searches over structured data with the summarization and navigation capabilities of tag clouds to help users access a database. We propose using clouds over structured data (data clouds) to summarize the results of keyword searches over structured data and to guide users to refine their searches. The cloud presents the most significant words associated with the search results. Our keyword search model allows searching for entities than can span multiple tables in the database rather than just tuples, as existing keyword searches over databases do. We present several methods to compute the scores both for...
