We propose an approach to modular agent-based land use modelling, based on ontologies in their computer science sense: formal representations of conceptualisations. The approach is primarily aimed at addressing the issue of model transparency. Human-natural systems models involve large numbers of submodels, making them difficult to understand for those not involved in their construction. We show that using ontologies to

A novel approach to generalisation is presented that is able, under certain circumstances, to guarantee the generalisation to binary-output data for which no targets have been given. The basis of the guarantee is the recognition of a persistent global minimum error solution. An empirical test for whether the guarantee holds is provided which uses a technique called target reversal. The technique employs two neural networks whose convergence using opposing targets signals validity of the guarantee.

The difficulties associated with adequately describing agent-based social simulation software in scientific journals necessitate the establishment of norms for making the software more accessible. We consider here norms for documentation and licensing that outline a manifesto for open simulation, which we hope the community will sign up to. Licensing in particular has a number of thorny issues associated with it: the default under the Berne Convention turns software into a black box, raising a question over whether it can ...
