Invited lecture on the technologies and research disciplines behind the, so called, Web 2.0 buzzword at Web 2.0 Live, November 2011, Taunton.

1. Simon Price, University of Bristol
Webs of People, Webs of Data
Web 2.0 Live, Taunton, Nov 2006

2. Web 2.0

3. Web Applications (Web 1.5?)

4. Hybrid Web-Desktop (Web 1.6?)

5. Canonical Web 2.0
• Amazon
– Customer Reviews
– Amazon Recommends
• Google
– PageRank™
– Making money out of links
– Google Mail, Maps, APIs, Desktop Search, ...

6. Web 2.0 Technology (nothing new)
• Minimum
– CGI (e.g. Perl, PHP, Python, C/C++)
– Database (e.g. MySQL, Postgres, Oracle)
• More recent additions
– Java
– XML
– Web Services
– AJAX
– Ruby on Rails

7. Social Networks
A key ingredient in the Web 2.0 melting pot

8. Google PageRank™
• Sergey Brin and Lawrence Page (Stanford, 1995)
• Intuition behind PageRank:
– Web is a network (graph) connected by links
– A link is a "vote" for the destination page
– Strength of vote is a fraction of the PageRank
of the page casting the vote

9. PageRank of a page is the
probability of a random
surfer arriving at that page
after many clicks.
(By Markov Theory)

14. The Web of Data

15. Semantic Web
The Semantic Web is a graph-based
knowledge representation of data, spanning
the Web, traditional databases, the desktop
and mobile devices.

16. Friend of a Friend (FOAF)
"The FOAF project is about creating a Web of
machine-readable homepages describing people, the
links between them and the things they create and do."
http://www.foaf-project.org/

17. FOAF and Co-depiction

18. PARIP
• PARIP = Practice As Research In Performance
– 5 year national project
– Led by University of Bristol's Department of Drama:
Theatre, Film, Television
– Professor Baz Kershaw and Dr Angela Piccini
• PARIP Explorer
– Innovative contacts and research database
– Developed by ILRT
– Semantic Web technology

19. PARIP - Data Fusion
• contact details
• research interests
• images
• interviews
• concepts
• questionnaire responses
• institutions
• projects
• …

20. PARIP - User Perspective
• Dual interface:
– Text View cross-database search-engine
– Map View visual link discovery and browsing

21. PARIP - Technical Perspective
• Semantic Web: RDF/XML and FOAF
• Prolog running as a Web Service (WSDL+SOAP)
• SPARQL query interface for programmatic access
• XHTML AJAX client
• Visualisation via Flash

22. Research Directions

23. Automated Data Fusion

24. Exabyte Scale Informatics
• 1 Exabyte = 1018
bytes
i.e. 1,000,000,000,000,000,000 bytes
• 1 Exabyte is approximately everything ever:
• written,
• composed,
• filmed,
• painted
• or in any other way 'recorded' by humans.
• Manual classification and retrieval is inadequate;
machine learning and data mining are essential.
