Uncertainty Annotated Databases - A Lightweight Approach for Approximating Certain Answers
Summary: UA-DBs fuse under- and over-approximations of certain answers to balance reliability and performance. Using incomplete K-relations, UA-DBs generalize incomplete databases, allow explicitly marked uncertain answers, and yield tight, high-utility approximations with efficient evaluation.
