Benefits of technology

This patent describes an improved version of the DeepQA engine, which helps medical professionals investigate patient conditions by answering natural language questions with factual information. The system can also automatically connect with experts in the field for additional information when a confidence level is low. The expert responses are then added to the system to improve future research on similar patient conditions.

Problems solved by technology

The increasing number of known diseases, syndromes, drug side effects, drug interactions and possibly rapid spread of contagions as a result of rapid movement of people and cargo throughout the world has created mass volumes of information which may be unwieldy to utilize when there is time pressure to make a medical decision.

Embodiment Construction

[0014]The inventors of the present and related inventions have recognized and anticipated problems not yet recognized by those skilled in the relevant arts. The inventors have realized that the paradigm presented by medical and health care industries to quickly find and evaluate possible medical conditions based on questions, clues, facts and factoids about a particular patient's condition(s) or group of patients conditions is not well satisfied by traditional web search engines. When presented with a new set of health conditions about a patient, for example, such as the patient's age, known health issues, vital signs, complaints, etc., all of which are “clues, facts and factoids” to a problem to be solved, the doctor or health care professional must deduce what the problem is—e.g., what one or more medical causes may be to blame for the patient's condition. When the health care professional uses a web search engine to retrieve information using key words, he or she may receive thou...

Abstract

A DeepQA engine is enhanced to provide a digital medical investigation tool which assists a medical professional in researching potential causes of a set of patient conditions, including clues, facts and factoids about the patient. The DeepQA engine provides one or more answers to a natural language question with confidence levels for each answer. If a confidence level falls below a threshold, the enhanced DeepQA engine performs a crowd sourcing operation to gather additional information from one or more domain experts. The domain expert responses are provided to the medical professional, and are learned by the enhanced DeepQA system to provide for better research of similar patient conditions in future queries.

Description

FIELD OF THE INVENTION[0001]The invention generally relates to automated crowd sourcing enhancements to deep question-answer architecture systems, including combinations of Natural Language Processing, Information Retrieval, Knowledge Representation and Reasoning, and Machine Learning technologies, and the field of open-domain question answering. The invention more particularly relates to such crowd sourcing enhancements in the fields of medicine and health care.BACKGROUND OF INVENTION[0002]International Business Machines Corporation (IBM) has published details of computing methods and technologies that are able to assist humans with certain types of semantic query and search operations, such as the type of natural question-and-answer paradigm of a medical environment. IBM researchers scientists have been working on Deep Question-Answering (DeepQA) methods that are able to understand complex questions posed (and input) in natural language, and are able to answer the question with en...
