Watson...is it one of the robots from Mystery Science Theater or the Smartest Golden Retriever ever?
Watson is Artificial Intelligence. A computer that thinks like you and me but light-years faster and doesn't have the brain-fog from last night's carb-loaded meal. To understand the basis of this, first, take how our search process has worked in the past. Previously, we could do a keyword search that would return a list of content listed in order of relevancy. Watson is different, it is based on Question-Answering technology. Instead of traditional search capabilities relying on computer-based "coding" language, Watson understands actual human languages. According to IBM, more than 100 different techniques are used to understand and analyze natural language, identify sources, find and generate hypotheses, find and score evidence and merge and track predictions. So instead of returning a list of content, it honestly answers your questions.
