The document discusses how cognitive AI can augment doctors and clinicians by helping them address various challenges. It describes how doctors are challenged by the large volume of disparate data from various sources, keeping up with the constantly increasing research literature, selecting personalized treatment plans, and generating novel insights. Researchers face challenges such as exploring connections across domains and generating new insights. The document then introduces IBM Watson and describes how its capabilities such as natural language processing, machine learning, and visual recognition can help extract insights from vast amounts of data and published literature to help doctors understand patient conditions, formulate treatment options, and select personalized plans. It asserts that cognitive AI can engage patients, improve outcomes, and control costs in healthcare.
