Social networks often forms very complex structures that additionally change over time. Description of actors' roles in such structures requires to take into account this dynamics reflecting behavioral characteristics of the actors. A role can be defined as a sequence of different types of activities. Various types of activities are modeled by pattern subgraphs, whereas sequences of these activities are modeled by sequence diagrams. For such defined roles, a role identification procedure is proposed assigning to each actor his or her primary role played in a dynamic social network.
Resumen: Este artículo indaga sobre los estadios de integración de las asociaciones de inmigrantes en España según el stock de capital social que detentan, específicamente, dadas las relaciones que establecen con actores del entorno, y consecuentemente el rol que de esto se deriva para cada tipo de contraparte. Los datos se extraen de una muestra representativa conformada por 225 asociaciones de inmigrantes de todo el territorio español. Los resultados apuntan a que las asociaciones de inmigrantes juegan roles específicos y cohesivos con sus pares, incluso logran ciertas asimetrías en su favor con determinados actores de la sociedad de acogida. Por otro lado, los actores nativos de la sociedad de acogida se distribuyen en un continuo que va desde el desarrollo de roles específicos hasta otros múltiples, e incluso contradictorios, lo que, en su conjunto, termina por dibujar un complejo y diverso mapa de oportunidades para la integración de las asociaciones.
Social networks as structures reflecting social relations between individuals or organizations are often studied in order to identify roles of actors of the network. Classification of roles played by the actors can be very informative because it gives us the complete overview of the network allowing for understanding how the network is organized and how it is going to behave in front of certain external or internal events. In the paper we present how this task can be accomplished with support of OWL-based ontology and related tools. As a sample social structure we use a network of e-mail users.
