Abstract: Systems and techniques are disclosed for representing information included in unstructured text documents into a structured format. The systems and techniques identify events and information associated with the events in unstructured documents, classify the identified events and information, and represent the identified events and information in a structured format based on a computed classification score. The systems and techniques may also assign a confidence score to identified events, compare the confidence score associated with events to a confidence score associated with a trained confidence model, and represent the identified events and information associated with the events in a structured format based on the comparison.
