Possibilistic Network. Social Polarization in the Metropolitan Area of Marseille (France).

Tettamanzi, Andrea; Fusco, Giovanni

This R-script builds and executes a possibilistic network which has the same structure as the Baysesian network proposed by F. Scarella [2] in order to model social polarization in the metropolitan area of Marseille (France). The model can be used to infer a trend scenario of social polarization of the 439 municipalities in the metropolitan area of Marseille (France) in a 10 year time. Within the model, a valorized municipality is defined as a municipality where executives and professionals are overrepresented within its resident population; a devalorized municipality is defined as a municipality where the unemployed are overrepresented within its resident population.

The initial data for the study area were elaborated for 2009 and are in the Data_Marseille_2009.txt file. Other auxiliary files are:

 - DependentVariables.txt containing the dependency structure of the possibilistic network

 - VariableModalities.txt containing the values of each variable of the network

- VariableModalities_PlainEnglish.txt gives plain English names to variables and modalities, but is not used by the R-script.

- ModelStructure.png visualizes the DAG structure of the possibilistic network

The network is build using uncertain logical gates ([3], [4]), which are the possibilistic counterpart of  the noisy logical gates used in Bayesian networks [2].  More thorough presentations of the model and of the model results are available in [5] and in [6].

Model results and comparison with Bayesian network results can be explored through an interactive data-visualization at the following address: https://public.tableau.com/profile/fusco#!/vizhome/RepresentingUncertainFutures/Story1
