In this study, we propose a formal framework for user profile representation with hypergraphs. We exploit the framework to aggregate partial profiles of the individual to obtain a complete, multi-domain user model, since we aim to model the user from several perspectives. We use Freebase commons package concepts as pre-defined domains. The proposed user model is also capable of extracting user domain capsules, which models the user for the domain of interest. Moreover, using a hypergraph data structure results in solving connection-based problems easily, since the cost of local operations on a graph is low and independent of the size of the whole graph. Many problems in user modelling domain are connection-based problems, such as recommendation.
