Semantic?

What is syntax? How you
say something.

What is semantic? The meaning
behind what you say.

Web page is written in
HTML

HTML describes the syntax not
the semantics.

for example,
I love you.

I love you. Does the
meaning changed? No, but machine don’t know.

what machine see what human
see http://www.w3.org/TR/xhtml-rdfa-primer/

The goals of semantic web
Spend less time searching Spend less time looking at things that do not matter Spend less time explaining what we want to computers

The problems of current web

When you try to organize
a trip on the web...

You have to consult a
large numbers of sites. You had to mentally integrate all those information to achieve your goals. Ivan Herman, 2009

friend list on social network...

You had to type in
and connect with friends again and again for each site.

Why?

Because current web is web
of documents.

Documents is unstructured.

unstructured data structured data word
document excel spreadsheet

current web vs. semantic web
unstructured data structured data web of document web of data

Semantic web enables people to
share content beyond the boundaries of applications and websites.
