A population represents a group of interconnected individuals European society does not have the same features as an African sharing information. In this paper, the population we generate one. The model of the population has to respect the codes is detailed by socio-cultural features, specifically the way that of the society in order to accurately simulate the information people tend to link together. To this end, the use of a social diffusion. Furthermore, the relationships between people are network is a little bit restrictive: people are linked by only one relationship. Multidimensional Social Networks (MSN) model too complex to be modeled by one link. Social networks are, 3D social networks where each dimension represent a kind of for this purpose, a good but simple way to resume relationships relationship [1]. This architecture allows us to better represent between people. Nevertheless, social networks are generally the diversity of humans relations but also define distinctive based on only one relationship between people, or an ag- rules for the message diffusion simulation. The inner idea is gregation of several relationships into one. Multidimensional that information disseminates differently according to the links social networks (MSN) begin to emerge due to the importance through which the information propagates. So, we present in this of each relationship in the communication process [4], [5], paper the modeling of our MSN based on social science and a [6].

In this paper, we model an MSN with the idea new and more efficient systems for social simulation. The that information disseminates differently according to the link issues explored include psychology, organizational behavior, through which the information propagates: people do not sociology, political science, economics, anthropology, geogra- receive and transmit in the same way an information according phy, engineering, archaeology and linguistics [2], [3].

Following this simulation systems have to support deeply detailed analysis of postulate, we present in this paper the general framework of individual’s behavior. The SICOMORES project, in which we our MSN in order to generate a model of a population based on are involved, is a military project whose aim is to model a several relationships. Using social science research we describe population of interconnected individuals in order to simulate some relationships representing a part of the human social life. and observe the reaction of this population face to different information.

The actions deployed in this context are features. This framework is really adaptable thanks of the divided into influence and combat actions. Combat actions is MSN architecture which allows to separate and distinguish rather limited in the context of stabilization operation, priority the relationships the one from the others, to add or delete is given to actions of influence. These actions of influence a dimension, and to set for each dimension its own features can be defined as all the intentional activities to achieve an and diffusion rules.

Finally, Forestier et al. propose a MSN from online this time to nowadays, researchers have looked to improve discussions where relations are from discussion structure and the graph generation to respect social network features [8]: text content. These relations help to find celebrities in the degree distribution, assortativity, clustering coefficient, small discussions [5]. So, MSN model has a really big interest in world structure [9] and group structure.

Thus, researchers aim III. GENERAL FRAMEWORK to generate automatically social networks according to these features.
