Description logics provide powerful languages for representing and reasoning about knowledge of static application domains. The main strength of description logics is that they offer considerable expressive power going far beyond propositional logic, while reasoning is still decidable. There is a demand to bring the power and character of description logics into the description and reasoning of dynamic...
Dynamic description logic (DDL) is among the few emerging service composition solutions through logical reasoning. To overcome low efficiency and lacking context-aware support of DDL reasoning, we propose a new DDL-based service composition model, which supports context-based service pre-filtering over DDL reasoning space. The pre-filtering runs under the BPEL workflow and a distributed reasoning...
This paper presents a dynamic description logic and a sound and complete tableau-based satisfiability-checking algorithm for it. This logic is a combination of a typical action theory and the description logic ALCO@, with a feature that actions are treated as citizens. On the one hand, actions are represented over ontologies expressed in description logic; On the other hand, actions can be used as...
