  • 17. “in the background we discussed things more deeply than the guys on the stage”
    versus
    “Twitter can be distracting - you pay less attention”

  • 18. Number of Tweets at ED-Media 2009
  • 19. “... top trend makers show who is the heartbeat of this online community and the key terms pointed out, what the community was talking about”

  • 20. Research outcomes – Twitter can be used in the context of conferences:
    • for communication amongst participants
    • 21. for communication amongst organizers /presenters and audience
    • 22. for reporting to non-participants about the conference

  • 23. Research Question:
    Is Twitter useful to report from a conference in order to share the event with the scientific community outsidethe conference?
  • 24. Study:
    • Educamp Hamburg 2010 (barcamp; unconference)
    • 25. Twitter was monitored from 5.2 – 4.3.2010 (usedHashtag #ec10hh)
    • 26. In summary 2110 tweets were examined
    • 27. Two stage analysis – automatically and manually
  • Four categories of Tweets:
    • Irrelevant Tweets “Who found my drinking cup? #ec10hh”
    • 28. Administrative Tweets “Wifi is not available #ec10hh”
    • 29. Topical Discussions “nice idea of @estudyskills Aggregation of all student weblogs at Tumblelog gives overview”
    • 30. Topical Tweets “open-learning: initiative on OER usage for informal education: http://u.nu/4a7ya #ec10hh”
  • Categories of Tweets (manual analysis)
  • 31. Detailed Analysis of Tweets (manual analysis)
  • 32. Discussion
    • Keyword extraction (automatically analysis) did not show any interesting result – no direct correlation
    • 33. In average each user posted 6 tweets during the conference period
    • 34. High number of Retweets (18%) – often not useful without the necessary context
  • Main Outcome:
    If we reduce the tweets to those occurring during the conference period (5th and 6th February) only 120 posts are of interest at all, which relates to about 6%
  • 35. Interpretation – Twitter usage follows other logic:
    • usage as backchannel with limited comprehension potential for outsiders
    • 36. usage of self promotion and profiling to generate attention for own profile
    • 37. documentation and illustrating connections
    • 38. usage as a public notepad
    • 39. usage as an evaluation tool
  • Outlook:
    What must a web-based applicationthat can also be used offline (without Internet connection) for information retrievaland knowledge discoverybased on a micro-content system like Twitter look like?
  • 40. http://grabeeter.tugraz.at
  • 41. Archive and Searchoffline
  • 42. Grabeeter allows ...
    • Micro-content (tweets) is achievable due to the fact that any tweet can be retrieved at anytime from a local hard-drive
    • 43. Micro-content is storable in a way that the user can distinguish between different events
    • 44. Micro-content is searchable along keywords, hashtags, time frames as well as different entities (URLs, @, ... )
  • Microblogging has potential for the future
    - if we see it as a new
    communication channel
