Professor Smith has collected 7,500 words for emotions or those with emotional connotations, and built two systems involving emotions. The first, called Dr. Bob, retrieves stories from the Big Book of Alcoholics Anonymous, and those on childhood sexual abuse. It is a memory-based reasoning system about emotions. The second, named Alex, is a computer aid for treating alexithymia, a cognitive-affective disorder that causes patients to have difficulty identifying their emotions.
Physicians then order numerous, often expensive tests to determine what is wrong.
About 30 percent of people are alexithymic, placing a heavy burden on the health-care system. Alex helps patients become aware of their emotions more quickly, allowing physicians to diagnose problems sooner. In addition to researching emotions, Professor Smith has written three books, cowritten a fourth, and written or cowritten more than fifty scholarly articles.
