  2. Semantic Web: The Vision Hi Pete, it’s Lucy. I’m at the doctor’s office. Mom needs to see a specialist and then has to have a series of physical therapy sessions. Biweekly or something. Can you split the chauffeuring with me? Great! I’ll have my agent set up the appointments. Hello? Sure Lucy. RING … RING ... * Berners-Lee, Hendler, Lassila “The Semantic Web” Scientific American, May 2001

  3. The Vision Lucy’s agent looks up several lists of providers and checks for ones in-plan for Mom’s insurance, within a 20-mile radius of her home, and with a rating of excellent or very good. Schedule a treatment plan for Mom using Pete and my schedules. Only use providers that are in-plan for Mom’s insurance, are within a 20-mile radius, and have a rating of excellent or very good. Lucy’s agent formulates a schedule of appointments for therapists with appointments available that fit into Pete and Lucy’s schedule. Lucy’s agent retrieves information about Mom’s prescribed treatment from the doctor’s agent. Semantic Web * Berners-Lee, Hendler, Lassila “The Semantic Web” Scientific American, May 2001
