IBM Research announced two new Watson-related cognitive computing projects for the medical field.

IBM Research announced two new cognitive computing technologies, based on Big Blue’s Watson supercomputer system that are expected to help physicians make more informed and accurate decisions faster and to cull new insights from electronic medical records (EMR).

The two Watson-related cognitive projects, known as “WatsonPaths” and “Watson EMR Assistant,” are the result of a yearlong research collaboration with faculty, physicians and students at Cleveland Clinic Lerner College of Medicine of Case Western Reserve University. Both are key projects that will create technologies that can be leveraged by Watson to advance the technology in the domain of medicine, IBM said.

With the WatsonPaths project, IBM scientists have trained the system to interact with medical domain experts in a way that’s more natural for them, enabling the user to more easily understand the structured and unstructured data sources the system consulted and the path it took in offering an option. The Watson EMR Assistant project aims to enable physicians to uncover key information from patients’ medical records in order to help improve the quality and efficiency of care.

"WatsonPaths is designed to augment the problem-based learning methods that Cleveland Clinic medical students employ in the classroom,” J. Eric Jelovsek, M.D., director of the Cleveland Clinic Multidisciplinary Simulation Center, said in a statement. “The vision is for WatsonPaths to act as a useful guide for students to arrive at the most likely and least likely answers to real clinical problems, but in a classroom setting. Of course, it is also easy to visualize how this type of technology could eventually be a tool for physicians to use in real-time clinical scenarios—a powerful guiding reference to consult when diagnosing and identifying the best treatment options."

After displaying Watson’s capabilities on the game show, Jeopardy, where the system trounced human competitors, IBM announced that health care would be a key area of focus for future Watson applications. The new technology is not yet available for everyday commercial use.

“On Jeopardy it was not necessarily critical to know how Watson arrived at its answer,” Eric Brown, IBM Research director of Watson Technologies, said in a statement. “But doctors or domain experts in any field will want to understand what information sources Watson consulted, what logic it applied and what inferences it made in arriving at a recommendation. Through our research collaboration with Cleveland Clinic, we've been able to significantly advance technologies that Watson can leverage to handle more and more complex problems in real time and partner with medical experts in a much more intuitive fashion. These are breakthrough technologies intended to assist future versions of Watson products."

IBM said WatsonPaths delves into a complex scenario and draws conclusions much like people do in real life. When presented with a medical case, WatsonPaths extracts statements based on the knowledge it has learned as a result of being trained by medical doctors and from medical literature. The system works its way through chains of evidence—pulling from reference materials, clinical guidelines and medical journals in real-time—and draws inferences to support or refute a set of hypotheses. This ability to map medical evidence allows medical professionals to consider new factors that may help them create additional differential diagnosis and treatment options, IBM said.
