Abstract:
Computerized methods are disclosed for automated question generation from source documents through natural language processing, for applications including training and testing. Interleaved selection and transformation phases employ combined semantic-syntactic analysis to progressively refine natural input text into a high density of text fragments having high content value. Non-local semantic content and attributes such as emphasis attributes can be attached to the text fragments. The text fragments are reverse parsed by matching against a precomputed library of combined semantic-syntactic patterns. Once the patterns of each fragment are determined, transformation of fragments into question-answer pairs is performed using question selectors and answer selectors tailored to each pattern. Methods for constructing distractors, both internal and external, are also disclosed. The ecosystem of machine learning components, ontology resources, and process improvement are also described.

Claim (Index 20):
A computer-implemented method for generating one or more questions, comprising:\n receiving one or more source documents; analyzing the source document(s);\n wherein the analyzing comprises determining respective first content values for portions of the source document(s); \n first selecting one or more of the portions based upon the respective first content values; resolving coreferences in the first selected portion(s); first transforming the first selected portion(s) into one or more second version documents comprising transformations of the resolved coreferences; reverse parsing the second version document(s) using a pattern library to second select one or more fragments of the second version document(s); second transforming the second selected fragment(s) into the question(s).
