Abstract: A first set of an entity is received, where the first set of data includes distinct characteristics of the entity. A second set of data on one or more domains of the entity is received. Using the first and second set of data, a probabilistic knowledge graph for the entity is generated that includes an entity node, a first plurality of nodes, and a second plurality of nodes. The first plurality of nodes are connected to the entity node and represent each of the distinct characteristics. The second plurality of nodes are connected via probabilistic edges, where each of these probabilistic edges has an associated confidence score. This confidence score is determined using the second set of data.
