The document discusses the semantic web, which aims to present web page data in a way that is understood by computers, allowing machines to search, aggregate, and combine information without human operators. It is an extension of the current web that adds new machine-readable data and metadata to existing documents to enable both automatic processing by machines and manual use by humans using technologies like RDF.

1. A presentation on semantic
web-the next generation
world wide web.
In near future, the
data on the internet would
not merely be html files in
the form of documents, it
would be more meaningful
through ontology.
An extension of the current
Web that provides an easier
way to find, share, reuse and
combine information more
easily. It's based on
machine-readable
information and builds on
XML technology's capability
to define customized tagging
schemes and RDF's flexible
approach to representing
data.

3. o Web 1.0
 Mostly read only pages
 Mostly about companies(Dot com)
 Was about home pages.
 Was about wires.
 Was about Netscape.
o Web 2.0
 Mostly read/write pages
 Mostly about communities.(Facebook, MySpace)
 Is about blogging.
 is about wireless.
 is about search engines like Google, Dogpile, Altavista.

4. • The semantic web is focused on machines.
• The current web requires human operators to
perform searching and displaying contents.
• The Semantic Web is a project that aims to change
that by presenting Web page data in such a way that
it is understood by computers, enabling machines to
do the searching, aggregating and combining of the
Web's information — without a human operator.

5. • Semantic web is not separate entity from www.
• extension to the Web that adds new data and
metadata to existing Web documents, extending
those documents into data.
• This extension of Web documents to data is what
will enable the Web to be processed automatically
by machines and also manually by humans.
• To do this RDF (Resource Description Framework) is
used to turn basic Web data into structured data
that software can make use of.
• RDF works on Web pages and also inside
applications and databases.

6. • Short for Resource Description Framework.
• general framework for describing a Web site's
metadata, or the information about the information
on the site.
• details information such as a site's sitemap, the
dates of when updates were made, keywords that
search engines look for and the Web page's
intellectual property rights.
• It provides interoperability among applications that
exchange machine-understandable information on
the Web.

7. • Areas of research and life sciences where it can help
researchers by aggregating data on different
medicines and illnesses that have multiple names in
different parts of the world.
• Few companies implementing semantic web
technology:
 Oracle as Oracle Technology Network
 Twine-Knowledge Networking Application
 Joost-online television service
