Incompleteness in Information Integration
Summary: Proposes Incomplete Information Integration (III) to model incompleteness across sources, integrated DB, and queries. Extends local- and global-as-view query answering to SQL NULLs and Codd tables; analyzes semantics, complexity, and approximate algorithms for incomplete answers.
