چکیده |
Uncertainty reasoning has been identified as an
important and challenging issue in the database research.
Many logic frameworks have been proposed to represent
and reason about uncertainty in deductive databases. On
the basis of the way in which uncertainties are associated
with the facts and rules in programs, the approaches of
these frameworks have been classified into “annotation
based (AB)” and “implication based (IB).” When extending
both frameworks with certainty constraints, they become
equivalent in terms of expressive power. In this paper, we
propose a uniform environment to evaluate and experiment
with logic programs in AB and IB frameworks at the same
time. We also extend the existing query processing to handle
certainty constraints and we carry out experiments to
evaluate its performance. Our experiments and results
indicate that the proposed techniques yield tools that are
capable to reason with uncertainty. |
