The current (syntactic / structural) Web

Was the Web meant to be more?

“ An extension of the current Web in which information is given well-defined meaning, better enabling computers and people to work in cooperation.”

Sir Tim Berners-Lee et al., Scientific American, 2001: tinyurl.com/i59p

“… allowing the Web to reach its full potential…” with far-reaching consequences

“ The next generation of the Web”

What is the Semantic Web?

The Semantic Web in essence

The word “semantic” stands for “the meaning of”:

The Beatles were a popular band from Liverpool; Lennon was a member of the Beatles; "Hey Jude" was recorded by the Beatles

The Semantic Web is a Web that is able to describe things in a way that computers can understand

What is Web 2.0?

The term Web 2.0 was made popular by Tim O’Reilly:

http://www.oreillynet.com/pub/a/oreilly/tim/news/2005/09/30/what-is-web-20.html

http://en.wikipedia.org/wiki/Web_2.0

“ Web 2.0 … has … come to refer to what some people describe as a second phase of architecture and application development for the World Wide Web.”

The Web where “ordinary” users can meet, collaborate, and share using social software applications on the Web (tagged content, social bookmarking, AJAX, etc.)

Popular examples include:

Bebo, del.icio.us, digg, Flickr, Google Maps, Skype, Technorati, orkut, 43 Things, Wikipedia…

A move from the Web to a “social Web”

Web 2.0 and social software

Web 2.0 focuses include:

The Web as a platform for social and collaborative exchange

Reusable community contributions

Subscriptions to information, news, data flows, services

Mass-publishing using web-based social software

http://en.wikipedia.org/wiki/Social_Software

“ Social Software lets people rendezvous, connect or collaborate by use of a computer network. It results in the creation of shared, interactive spaces…”

Social software for communication and collaboration:

IM, IRC, Forums, Blogs, Wikis, Social Network Services, Social Bookmarks, Podcasts, MMOGs…

When did Web 2.0 appear?

Web 2.0 elements

What are tagging and folksonomies?

Tag:

A keyword which acts like a subject or category

Folksonomy:

A collaboratively generated, open-ended labeling system that enables Internet users to categorise content using tags:

Web links and pages (e.g. del.icio.us) using “social bookmarking”

Online photographs (e.g. Flickr, Zooomr)

Events (e.g. Upcoming.org)

Blog entries, etc.

Tag cloud:

A visual depiction of the tags used on a website:

Equivalent to a weighted list in the field of visual design

The path to Web 3.0 (the Semantic Web)

The Semantic Web effort is mainly towards producing standards and recommendations that will interlink applications

The Web 2.0 meme is about providing user applications

Not mutually exclusive:

With a little effort, many Web 2.0 applications can and do use Semantic Web technologies to great benefit

We will now discuss Web 2.0 and describe what happens when we combine it with the Semantic Web
