Pariah is a reputation system that calculates transitive trust and distrust relationships in a social network represented as a signed, directed graph.
Pariah can be used to model realistic social behavior amongst crowds of NPCs and help users make informed decisions about who to trust in a complex network of alliances.
This version is limited to social networks consiting of twenty distinct entities or less and when calculatin reputation only considers paths through the graph with a length of four hops or less.
More information on the design of Pariah can be found here.
