Learning Objects And Facts From Documents

Abstract

A system, method, and computer program product for learning objects and facts from documents. Embodiments of the method comprise selecting a source object and a source document and identifying a title pattern and a contextual pattern based on the source object and the source document. A set of documents matching the title pattern and the contextual pattern are selected. For each document in the selected set, a name and one or more facts are identified by applying the title pattern and the contextual pattern to the document. Objects are identified or created based on the identified names and associated with the identified facts.

What is claimed is: 
     
         1 . A method comprising:
 at a computing device having one or more processors and memory storing one or more programs for execution by the one or more processors:   selecting a source object from a plurality of objects stored in a fact repository, the source object having an object name and a fact including an attribute-value pair;   selecting a source document associated with the fact;   identifying a title pattern for the title of the source document based on a first syntax of (i) the title of the source document, and (ii) the object name of the source object within the title of the source document;   identifying a contextual pattern for the content of the source document based on a second syntax of (i) the attribute and (ii) the value related to the attribute-value pair of the source object, wherein the contextual pattern specifies a structural pattern with which the attribute-value pair of the source object is presented;   selecting a second document based on a determination that (i) content of the second document matches the identified contextual pattern and (ii) a title of the second document matches the title pattern;   identifying a new object name and a new attribute-value pair from the second document by applying the identified title pattern and the contextual pattern to the second document; and   storing in the fact repository the new attribute-value pair and a new object having the new object name.
