The document discusses the evolution of web technologies and applications, emphasizing Web 2.0 concepts such as social networks and Google's PageRank algorithm. It also describes the Semantic Web and its potential for knowledge representation, along with the 'Friend of a Friend' (FOAF) project. Additionally, it presents the PARIP initiative from the University of Bristol, focusing on data fusion and innovative research methodologies using semantic web technologies.
Webs of People, Webs of Data
- 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)
- 10. Newsgroup Mining Work by Jonathan Roberts
- 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/
- 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
- 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.
