Abstract


This is a position paper that presents a new approachto identifying important nodes or entities in a complexheterogeneous network. We provide a novel definitionof an importance score based on a statistical model: Anindividual is important to the extent that including anindividual explicitly in the model improves the data fit of the model more than it increases the model’s com-plexity. We apply techniques from statistical-relationallearning, a recent field that combines AI and machinelearning, to identify statistically important individualsin a scalable manner. We investigate empirically our approach with the OPTA soccer data set for the Englishpremier league.
