Uncertain Deductive Databases: A Hybrid Approach.
Lakshmanan, Laks V. S.; Sadri, Fereidoon
Information Systems, v22 n8 p483-508 Dec 1997
Considers a "hybrid" approach to the modeling of uncertainty in deductive databases. The model, deductive IST (DIST) is based on an extension of the "Information Source Tracking" (IST) model for relational databases. Proves that the complexity of testing containment of conjunctive DIST queries remains the same as in the classical case when number of information sources is regarded as a constant. (Author/AEF)
