【 摘 要 】

Instance-uni¯cation is a prime example for uncertainty onthe Semantic Web, as it is not always possible to automatically determine with absolute certainty whether two references denote the same object or not. In this paper, we present openacademia, a semantics-based system for the management of distributed bibliographic information collected from the Web, in which the Instance Uni¯cation problem is ubiquitous. Our tentative solution is Rough DL, a simple extension of classical De- scription Logics, which allows for approximations of vague concept. This shows that already a simple formalism for dealing with uncertain infor- mation in a qualitative way can provide an elegant solution to practical
