Abstract

A repository contains objects including facts about entities. Objects may be of known or unknown entity type. An entity type assignment engine assigns entity types to objects of unknown entity type. A feature generation module generates a set of features describing the facts included with each object in the repository. An entity type model module generates an entity type model based on the sets of features generated for a subset of objects. An entity type model module generates entity type models, such as a classifier or generative models, based on the sets of features associated with objects of known entity type. An entity type assignment module generates a value based on the sets of features associated with an object of unknown entity type and the entity type model. This value indicates whether the object of unknown entity type is of a known entity type. An object update module stores the object to which the known entity type was assigned in the repository in association with the assigned entity type.
