The planet Earth simulator project - a case study in computational semiotics

The planet Earth simulator (PES) project is presented here as a case study in computational semiotics. The PES-project is a Web-based platform for the accumulation and simulation of knowledge. Knowledge is here understood as a dynamic structure which enables human and non-human systems to model the world, to guide their behavior and to set up meaningful languages for communications. The PES-project provides a graphical user interface and a scalable interactive multiuser simulation environment with inherent parallel and real time processing. The PES-project can be seen as another instructive example for the conceptual power of computational semiotics
