4. Web 1.0
• Read-only Content and Static HMTL
websites

5. Web 2.0
• User Generate Content and Social network

6. Web 3.0
• Semantic Web, machine can read the data
and help us

7. Semantic Web?
• The sites you visit every day use natural
language, images and page layout to
present information
– easy for you to understand.
• But computers can't make sense of all this
information.
– can't read, see relationships or make decisions
like you can.
• The Semantic Web proposes to help
computers "read" and use the Web.

8. Introduction to How Semantic
Web Works
• The idea is pretty simple
– metadata added to Web pages can make the
existing World Wide Web machine readable.
• It will give machines tools to find, exchange
and, to a limited extent, interpret
information.
• It's an extension of the World Wide Web.

9. Why Semantic Web?
• Suppose you want to buy something online
with some basic criteria
 Your best bet would be to
 look at different retailers' web
pages, comparing prices and
shipping times and rates; or
 look for a site that will
compare prices and shipping
options from several retailers
all at once.

10. Why Semantic Web?
• With the Semantic Web, you could enter
your preferences into a computerized agent
– which would search the Web, find the best
option for you, and place your order.
• The agent could then
– open personal finance software and record the
amount you spent on your computer,
– mark the date of arrival on your calendar.
– learn your habits and preferences
Page 10 of 23

11. Why Semantic Web?
• The agent would do by searching through
metadata that clearly identify and define
what the agent needs to know.
• Metadata
– simply machine-readable data that describe
other data.
– invisible as people read the page, but they're
clearly visible to computers.
• Metadata can also allow more complex,
focused Web searches with more accurate
results.

12. • When you try to search some information on
the web...
• You have to
– consult a large numbers of sites.
– mentally integrate all those information to
achieve your goals.
• Because current web is web of documents.

13. • Documents is unstructured, i.e.:
unstructured data structured data
excel spreadsheetword document

14. Why Semantic Web?
• Semantic web enables people to share
content beyond the boundaries of
applications and websites.
• The goals are Spend less time on:
– Searching
– looking at things that do not matter
– explaining what we want to computers

15. W3C and the Future of the
Semantic Web
• Decentralization gives developers the freedom
to create precisely the tags and ontologies that
they need.
• But, different developers might use different
tags to describe the same thing, make machine
comparisons difficult.
• Critics also question the "identity problem"
– does a URI represent a Web page, or does it
represent the concept or object the page describes.
• In the future, off-the-shelf software might
include options for adding metadata when
creating new documents

16. Web 3.0 in Digital Libraries
• Semantic digital libraries
– integrate information based on different
metadata, e.g.: resources, user profiles,
bookmarks, taxonomies
– provide interoperability with other systems (not
only digital libraries) on either metadata or
communication level or
– delivering more robust, user friendly and
adaptable search and browsing interfaces
empowered by semantics

17. Benefits
• Benefits of Semantic Digital Libraries
• new search paradigms for the information
space
• providing interoperability on the data level
– integrating metadata from various
heterogeneous sources
– Interconnecting different digital library systems

18. Conclusion
• Semantic digital libraries can produce more
meaningful results for the user.
• Further developments have evolved the
concept of contribution of information and
social interactivity between the contributors.
• The future holds much more promising and
efficient mechanisms for handling
information.

19. Mobile apps in different
industries
In average, each person in Hong Kong owns
about 2.3 SIM cards
50% of them are Smartphones
– 70% of people use smartphone while eating
– 80% use it while watching TV, and
– 90% use it during the toilet time
