SOCIAL SEMANTIC WEB INTRO
Paola Monachesi
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.

The Semantic Web
It will make data located anywhere on the web accessible and understandable both to people and to machines.
Web 2.0
Elements of Social Web
Users contribute content Images (Flickr,), news stories (Digg, Reddit),
bookmarks (Delicious, Bibsonomy), videos (YouTube,), Personal information (Facebook)
Users add metadata to content Tags: annotate content with freely chosen
keywords Discussion: leave comments Evaluation: active through voting or passive
through views & favorites
Elements of Social Web
Users create social networks Add other users as friends/contacts Sites provide an easy interface to track
friends’ activities Transparency
Publicly navigable content and metadata
So what?
By exposing human activity, Social Web allows users to exploit the intelligence and opinions of others to solve problems New way of interacting with information Amenable to analysis
Challenge: harness the power of collective intelligence to solve information processing problems
What are the risks?

Is this what we will get?
A web of data
Data Interoperability across applications and organizations (for IT)
A set of interoperable standards for knowledge exchange
An architecture for interconnected communities and vocabularies
