Eigenvector

Eigenvector measures how connected an entity is and how much direct influence it might have over other connected entities in the network.

The eigenvector scores of the entities it is connected to, is considered. For example, a person with a high eigenvector score is likely to be at the center of a cluster of key entities that themselves have high eigenvector scores. That person can communicate directly with those key entities compared with a person with a low eigenvector score on the periphery of the network.

Hubs and authorities are the terms that are used to describe the two eigenvector scores that are calculated in networks that contain directed links. Hubs see the scores for outbound links, and authorities see the scores for inbound links. A high-scoring hub has many outbound links to high-scoring authorities, and a high-scoring authority has many inbound links from high-scoring hubs.
