This paper describes an Ei el system for rapid testing of grammars. Grammars are de ned in an extended BNF notation that allows actions on the parse tree nodes to be de ned as add...
Abstract. Time Petri nets have proved their interest in modeling realtime concurrent systems. Their usual semantics is defined in term of firing sequences, which can be coded in a ...
Ping-pong protocols with recursive definitions of agents, but without any active intruder, are a Turing powerful model. We show that under the environment sensitive semantics (i.e....
The development of scalable reasoning systems is one of the crucial factors determining the success of Semantic Web systems. Recently, in [GH06], an approach is proposed, which tac...
In our experiences building systems that use Semantic Web technologies, we have often identified a requirement for a consistent way to associate data values with standard units. We...
