Hypertext2007 Wendy Hall - "Whatever Happened to Hypertext?"

  1. 1. <ul><li>Professor Wendy Hall </li></ul><ul><li>University of Southampton </li></ul><ul><li>http://www.soton.ac.uk/~wh </li></ul>Whatever happened to hypertext?
  2. 2. “ As we may think” Vannevar Bush Atlantic Monthly July 1945
  3. 3. Ted Nelson and Doug Engelbart Everything is deeply intertwingled Augmenting human intellect
  4. 4. <ul><li>Hypertext Conference Series </li></ul><ul><li>1987 was a big year for hypertext. Apple launched HyperCard </li></ul><ul><li>First ACM Hypertext Conference – HT’87, Chapel Hill, North Carolina </li></ul><ul><li>ACM HT’89, Pittsburgh </li></ul><ul><li>Key feature was interdisciplinary nature of the conferences – authors and poets as well as techies </li></ul><ul><li>Systems around at the time included KMS, NoteCards, Guide, Intermedia, Microcosm, Hyper-G and the embyronic Web </li></ul>
  5. 5. ECHT’90
  6. 6. Fountain et al “Microcosm: an open model for hypermedia with dynamic linking” Proceedings of ECHT’90
  7. 8. Microcosm Linkbases Link database Documents Note the direction of this arrow! Separable hyperstructure
  8. 9. Links in Microcosm source, destination, description source: object | concept | context Focus on associative linking Different linkbases for different users We generated links based on metadata description of documents in docuverse and “it all falls out”
  9. 11. <ul><li>ACM Hypertext’91 </li></ul>
  10. 12. The rise and fall of the Hypertext conference series <ul><li>ECHT’92, Italy </li></ul><ul><li>ACM HT’93, Seattle – peak of attendance figures, big commercial exhibition, half the demo’s are Web </li></ul><ul><li>ECHT’94 (merged with ECHT), Edinburgh – Tim is keynote speaker (NB: WWW1, May 1994, Geneva) </li></ul><ul><li>ACM HT’96, Washington DC </li></ul><ul><li>ACM HT’97 (merged with ECHT), Southampton – 150 attendees, cf. 2,000+ attendees at WWW6 in California </li></ul><ul><li>Hypertext conferences in terminal decline (almost!) </li></ul>
  11. 13. Web conference series begins <ul><li>WWW1 – May 1994, Geneva </li></ul><ul><li>WWW2 – October 1994, Chicago </li></ul><ul><li>WWW3 – April 1995, Darmstadt </li></ul><ul><li>WWW4 – December 1995, Boston </li></ul><ul><li>WWW5 – 1996, Paris </li></ul><ul><li>WWW6 – 1997, Santa Clara, California. Paper accepted for conference that “reinvents” Microcosm generic links – index-based hyperlinks. Schedule clash with HT’97 in Southampton. Joint panel. Quote from Ted “Your future is my past”. </li></ul><ul><li>WWW7 – 1998, Australia. Annual WWW conference rotates between US, Europe and ROW. I join IW3C2. </li></ul><ul><li>Hypertext track established at WWW conferences </li></ul>
  12. 14. Lessons learnt: Big is beautiful: the network is everything (tbl) Scruffy works: let the links fail to make it scale (tbl) But we lost (for a time) conceptual and contextual linking Creating good hypertext in the Web is ironically very hard Missing links – search engines fill the gap
  13. 16. Ending the Tyranny of the Link <ul><li>“ We need to develop a new conception of hypermedia that includes non-network structures as well as virtual structures on an equal footing with network structures.” </li></ul><ul><li>Halasz, HT’91 </li></ul>A query is an unresolved link
  14. 17. The Proxy DLS DLS Agent client Link server Internet The DLS Agent is an HTTP proxy that inserts links on-the-fly by querying the link service
  15. 19. XML XLink XPointer <ul><li>Open Hypermedia Systems community influence on the Web? </li></ul><ul><li>What happened to contextual and conceptual linking? </li></ul>
  16. 20. COHSE <ul><li>Improving the quality, consistency and breadth of linking of Web documents using ontologies. </li></ul>
  17. 21. Artificial Intelligence
  18. 22. The Semantic Web Semantic Web LayerCake (Berners-Lee, 99;Swartz-Hendler, 2001)

  25. 29. The Web Science Research Initiative Creating a Science of the Web November 2006 Directors: Wendy Hall, Nigel Shadbolt, Southampton Tim Berners-Lee, Daniel Weitzner, MIT
  26. 30. What is Web Science? <ul><li>The Web has been transformational </li></ul><ul><li>Largest human information construct in history </li></ul><ul><li>How are we to </li></ul><ul><ul><li>Understand what it is </li></ul></ul><ul><ul><li>Engineer its future </li></ul></ul><ul><ul><li>Ensure its social benefit </li></ul></ul><ul><li>This requires a new interdisciplinary field </li></ul><ul><li>This field we call Web Science, or the Science of Decentralized Information Systems </li></ul>
  27. 31. Web Science Involves <ul><li>New Science </li></ul><ul><li>New Engineering </li></ul><ul><li>New Social Understanding </li></ul><ul><li>New Capacity </li></ul>
  28. 32. Research Agenda <ul><li>WSRI will generate a research agenda for understanding the scientific, technical and social challenge underlying the growth of the Web </li></ul><ul><li>Or particular interest is the volume of information on the Web that increasingly documents aspects of human activity and knowledge </li></ul><ul><li>WSRI research projects will weight questions such as: </li></ul><ul><ul><li>How do we access information and assess its reliability? </li></ul></ul><ul><ul><li>By what means may we assure its use complies with social and legal rules? </li></ul></ul><ul><ul><li>How will we preserve the Web over time? </li></ul></ul>
  29. 33. Why this is important? <ul><li>We cannot take for granted the freedom to exchange information that is at the heart of the Web </li></ul><ul><li>It has become our cultural legacy, our social heritage – we live in a web-dependent society in a web-dependent world </li></ul><ul><li>Protecting and preserving this freedom is a major challenge as big as any other global cause </li></ul><ul><li>If we don’t do this, who will? </li></ul><ul><li>This is as grand challenge and maybe an inconvenient truth! </li></ul>
  30. 34. www.webscience.org <ul><li>HT’07 Manchester – re-launch on series </li></ul><ul><li>WWW conference still going strong but has never attracted the hypertext crowd </li></ul><ul><li>The Semantic Web represents the re-birth of hypertext but the hypertext crowd won’t find much to interest them at ISWC and ESWC </li></ul><ul><li>The Web 2.0 conferences are too commercial? </li></ul><ul><li>Will we have to create a Web Science conference series? </li></ul>
