On Properties of Update Sequences Based on Causal Rejection
In this paper, we consider an approach to update nonmonotonic knowledge bases represented as extended logic programs under the answer set semantics. In this approach, new informat...

A Logic Based Approach for Dynamic Access Control
The PolicyUpdater1 system is a fully-implemented access control system that provides policy evaluations as well as dynamic policy updates. These functions are achieved by the use o...

Layer Supported Models of Logic Programs
Building upon the 2-valued Layered Models semantics for normal programs, we introduce a refinement — the Layer Supported Models semantics — which, besides keeping all of LMs...

A Language for Multi-dimensional Updates
Dynamic Logic Programming (DLP) was introduced to deal with knowledge about changing worlds, by assigning semantics to sequences of generalized logic programs, each of which repres...

Dynamic Logic Programming
In this paper we investigate updates of knowledge bases represented by logic programs. In order to represent negative information, we use generalized logic programs which allow de...
