Publication number: 20190325300Abstract: Information from a radiology report is obtained based on machine learning. Rather than a natural language processing system designed to answer a question based on a large corpus of generic information, deep learning is used to train a machine-learnt network to contribute to extraction of a patient-specific answer from a patient-specific radiology report. Natural language questions, including questions with less informed terminology from a patient and questions with more informed terminology from a physician, are answered using evidence from the patient-specific radiology report even where that report and/or questions are not used in training the machine-learnt network.Type: ApplicationFiled: April 19, 2018Publication date: October 24, 2019Inventors: Juan Xu, Puneet Sharma
