Kowalski and Sergot’s Event Calculus (EC) is a simple temporal formalism that, given a set of event occurrences, derives the maximal validity intervals (MVIs) over which propert...
A logical database schema, e.g. a relational one, is an implementation of a speci cation, e.g. an entity-relationship diagram. Upcoming new data models and the necessity of seamle...
The paper describes a decentralized peer-to-peer multi-agent learning method based on inductive logic programming and knowledge trading. The method uses first-order logic for model...
We propose a framework for the formal speci cation and veri cation of timed and hybrid systems. For timed systems we propose a speci cation language that refers to time only throug...
Programmable Logic Controllers (PLC) are widely used in process automation due to their fast and guarantee response time. However their programming and interfacing capacities are ...
