2. RING … RING... Hello? 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? Sure Lucy. Semantic Web: The Vision Great! I’ll have my agent set up the appointments. * Berners-Lee, Hendler, Lassila “The Semantic Web” Scientific American, May 2001

3. The Vision Semantic Web Lucy’s agent retrieves information about Mom’s prescribed treatment from the doctor’s agent. 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. * Berners-Lee, Hendler, Lassila “The Semantic Web” Scientific American, May 2001
