Abstract
Systems and methods are provided for determining an affinity score of a source entity and a target entity without consideration of data that directly links the source entity and the target entity. An intermediate entity that is relatable to a source entity is identified. A target entity is identified that is relatable to an intermediate entity. A similarity score is calculated identifying a degree of similarity between the source entity and the intermediate entity, or the target entity and the intermediate entity. An affinity score is calculated of the source entity and the intermediate entity, or the target entity and the intermediate entity. An affinity score of the source entity and the target entity is determined based on the similarity score and the affinity score.
