In this paper, an algorithm for obtaining consistent answers to queries posed to inconsistent relational databases is presented. The algorith is proven to be sound, terminating and...
In this paper we consider the problem of the logical characterization of the notion of consistent answer in a relational database that may violate given integrity constraints. Thi...

Higher-order narrowing is a general method for higher-order equational reasoning and serves for instance as the foundation for the integration of functional and logic programming. ...
The paper considers interdependencies between secrets in a multiparty system. Each secret is assumed to be known only to a certain fixed set of parties. These sets can be viewed as...
In this paper, we propose a new progression mechanism for a restricted form of incomplete knowledge formulated as a basic action theory in the situation calculus. Specifically, w...
