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.

Because current web is web of documents.

Documents is unstructured.

unstructured data structured data word document excel spreadsheet
