They must answer the question, but the response must have 30 seconds to respond. For example, Watson employs resource intensive scoring algorithms to a larger more than 50 scoring components that produce set of initial candidates to prune them down to a scores ranging from formal probabilities to counts smaller set of candidates before the more intensive to categorical features, based on evidence from dif- scoring components see them.
