Analyse des rôles dans les communautés virtuelles : définitions et premières expérimentations sur IMDb

RESUME. Analyser les roles dans les communautes virtuelles nous permet de mieux comprendre, voire de predire, le comportement individuel des internautes. Bien que de nombreuses approches aient ete proposees, on constate un manque de generalisation des methodes existantes et des resultats obtenus. Dans ce papier, nous passons en revue quelques theories developpees a propos des roles sociaux et nous cherchons une definition compatible a une automatisation par les machines de la detection des roles joues par les individus dans des fils de discussions sur internet. Nous analysons ensuite le site Web IMDb afin d’illustrer notre discours.
