Abstract. A social network is an abstract concept consisting of the set of people with relationships linking pairs of humans. A new multidimensional model, which covers three main dimensions: relation layers, time windows and groups, is proposed in the paper. The dimensions have a common set of nodes, typically, corresponding to human beings Layers, in turn, reflect various relation types coming from different user activities gathered in computer systems. The time dimension corresponds to temporal variability of the social network. Social groups are extracted by means of clustering methods and join people close each other. An atom component of the multidimensional social network are views – small social sub-networks, which are in the intersection of all dimensions. A view describes the state of one social group, linked by only one type of relationships (one layer), derived from within only one time period. The multidimensional model of the social network is similar to the general concept of data warehouses, in which a fact corresponds to a view. Aggregation possibilities and usage of the model is also discussed in the paper
