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.

The Vision
Semantic Web
Lucy’s agent retrieves informationabout 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’sinsurance, 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.
