The W3C's Semantic Web Activity is illustrating the use of semantics for information integration, search, and analysis. However, the majority of the work in this community ha...
The presence of uncertainty in the real world makes robustness to be a desired property of solutions to constraint satisfaction problems. Roughly speaking, a solution is robust if...
This paper presents a new blocking logic to block unknowns for temporal compactors. The proposed blocking logic can reduce data volume required to control the blocking logic and a...
We describe in this article an abductive procedure based on a constrained resolution principle. The choice of constrained resolution is motivated by the whish to gain full advanta...
—Past research on temporal databases has primarily focused on state-based representations and on relational query language extensions for such representations. This led to many d...
