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
