Agenda Introduction The Problem Solutions Applications Summary


Every language has its own Syntax and Semantics

Syntax is the study of grammar

Semantics is the study of meaning

Syntax is how to say something

Semantic is the meaning behind what you say

Different syntaxes may have the same semantic: x += y x=x+y

Syntax and semantics are all about communication

Computers use network protocols to communicate in networks

The Internet is a huge network of computers that use TCP/IP to communicate

The Web is a system of interlinked documents accessed via the Internet

Web browsers use HTTP to communicate with Web servers

You can view Web pages and use hyperlinks to navigate between them

People can easily access any of these documents

This is the largest source of information ever

This is Web 1.0

Authors started to use Ajax

People started to share photos and videos

People started to interact in social networks

People started to publish content in blogs

People started to contribute in wikis

People started to use tags and RSS

This is the Read-Write Web

This is Web 2.0

The Problem

Web pages are written in HTML

HTML describes the structure of information

HTML describes the syntax not the semantics

If computers can understand the meaning behind information...

they can learn what we are interested in

they can help us better find what we want

This is really what the Semantic Web is all about

This is Web 3.0

Today's Web is about documents

The Semantic Web is about things

It can recognize people, places, events, companies, products, movies, etc.

It can understand the relationships between things



Solution: Top Down

Information analysis, web scraping, natural language processing

Expensive! human intervention, hard to maintain, legal issues

Solution: Bottom Up

Embedding semantical annotations into the data


Available options: RDFa and microformats


RDF is Resource Description Framework

RDF is a W3C standard for describing resources in the Web

RDF identifies things using URIs (Uniform Resource Identifiers)

RDF uses simple statements (Triples) to describe things

Thing-Property-Value Subject-Predicate-Object

RDF graph representation


N3 (Notation3)

RDFa = RDF in attributes

RDFa provides a set of XHTML attributes that express RDF data

Example: Alice in Semantic Wonderland

Alice is a blogger who publishes articles at http://example.com/alice

She wants to declare the license of her work

She wants to specify title and creator of an article

But there are no such attributes in XHTML

She can use Dublin Core vocabulary Dublin: Dublin, Ohio, USA Core: only the core elements of metadata

She wants to give Bob proper credit when she posts his photos

She wants to display her name, email and phone

She can use Friend-of-a-Friend vocabulary

She wants to list her friends

SPARQL (SPARQL Protocol And RDF Query Language)

SPARQL is a query language for RDF data

You can search for "friends of Alice who created items whose title contains 'Bob'"


microformats are simple conventions for embedding semantics in HTML

designed for humans first, and machines second

No namespaces, No new tags

Built upon existing standards vCard, iCalendar, Atom, etc.

hCard (HTML vCard) represents people, companies, places and organizations

hCalendar (HTML iCalendar) Represents calendar events

hReview Represents reviews of products, services, businesses, events, etc.

hResume represents resumes


YahooTech uses hReview for product reviews

LinkedIn uses hResume for resumes

YahooUpcoming uses hCal for events

Challenges! tools, privacy, trust, applications, devices


“I have a dream for the Web in which computers become capable of analyzing all the data on the Web” Tim Berners-Lee, 1999 Inventor of the Web

The Semantic Web is not a separate Web but an extension of the current one

It is really happening today
