Entity Type Assignment

Abstract

A computer system creates a plurality of objects using facts derived from electronic documents, each object including one or more facts describing an entity associated with the object. The system generates a value for an object of an unknown entity type, of the plurality of objects, by using an entity type model for a known entity type. The entity type model is based on a set of features of a plurality of objects of the known entity type, and the value indicates whether the object of an unknown entity type is of the known entity type. The system assigns the known entity type to the object of an unknown entity type in response to a determination that the value indicates the object of an unknown entity type is of the known entity type, and stores the object with the assigned entity type.

1 . A computer-implemented method of assigning an entity type to an object of an unknown entity type at a computer system, the computer system comprising one or more processors and memory storing one or more programs, the object stored in the memory, the method comprising:
 creating a plurality of objects using facts derived from electronic documents, each object including one or more facts describing an entity with which the object is associated, wherein each fact comprises an attribute;   generating a value for an object of an unknown entity type, of the plurality of objects, by using an entity type model for a known entity type, wherein the entity type model is based on a set of features of a plurality of objects of the known entity type, and the value indicates whether the object of unknown entity type is of the known entity type;   assigning the known entity type to the object of unknown entity type in response to a determination that the value indicates the object of unknown entity type is of the known entity type; and   storing the object to which the known entity type was assigned with the assigned entity type.
