Cognitive modeling: a domain independent user modeling

The user model issue is analyzed in the context of domain dependence versus domain independence. One approach to user modeling involves building approximate responses to user needs based on knowledge level of the user. This approach to building user model has an advantage that it is relatively easy to construct such models. However, the model built is specific to the domain being handled Also, the model can not appropriately support the responses needed by experts working in an expert domain. This domain dependence problem in user modeling has been addressed here and a solution in the form of domain independent user model construction is being proposed The central aim of the paper is to present user modeling concept in the perspective of cognitive abilities of the user. The user model is constructed based on user's cognitive abilities which are in turn obtained through certain standard psychological tests. The response generated by the system will then be based primarily on an individuals cognitive abilities and will be independent of any particular domain.
