Abstract
(EN)
The claimed subject matter relates to an architecture that can identify, store, and/or output local contributions to a rank of a vertex in a directed graph. The architecture can receive a directed graph and a parameter, and examine a local subset of vertices (e.g., local to a given vertex) in order to determine a local supporting set. The local supporting set can include a local set of vertices that each contributes a minimum fraction of the parameter to a rank of the vertex. The local supporting set can be the basis for an estimate of the supporting set and/or rank of the vertex for the entire graph and can be employed as a means for detecting link or web spam as well as other influence-based social network applications.
(FR)
L'invention concerne une architecture qui peut identifier, mémoriser et/ou délivrer des contributions locales à un rang d'un vertex dans un graphe orienté. L'architecture peut recevoir un graphe orienté et un paramètre, et examiner un sous-ensemble local de vertex (par exemple, local à un vertex donné) afin de déterminer un ensemble de prise en charge local. L'ensemble de prise en charge local peut comprendre un ensemble local de vertex qui contribuent chacun pour une fraction minimale du paramètre à un rang du vertex. L'ensemble de prise en charge local peut être la base d'une estimation de l'ensemble de prise en charge et/ou du rang du vertex pour le graphe entier et peut être utilisé en tant que moyen pour détecter un lien ou un spam Web ainsi que d'autres applications de réseaux sociaux basés sur des influences.
