摘要：In their widely discussed May 2001 article on the Semantic Web in Scientific American (www.sciam.com/article.cfm?articleID=00048144-10D2-1C70-84A9809EC588EF21) Tim Berners-Lee, James Hendler and Ora Lassila present a scenario in which a person named Pete is listening to the Beatles through his home entertainment center. Lucy, Pete’s sister, phones from the doctor’s office to explain that their mother needs a series of bi-weekly physical therapy sessions. The first few paragraphs of this article tell how both Pete’s and Lucy’s Semantic Web agents (hereafter referred to as agents) communicate with each other and transverse the Semantic Web to schedule their mother’s physical therapy session, how Pete is not pleased with the initial plan and how later that evening Pete sends his agent back onto the Semantic Web to find an alternative plan. Pete’s Web agent completes this second task and reschedules several of his personal and less important work appointments.
