> What does "weaker relationship" mean, though?
John's barber is Bob. (weaker relationship) John's father is Bob. John's twin is Bob. (stronger relationship)
A stong relationship allows more specific information to be derived. For example, an AI-type program probably couldn't deduct if John and Bob have the same eyeColor if Bob is John's barber. But if Bob is John's twin, it has a much better chance. Received on Sun Feb 29 2004 - 00:07:52 CST
