  1. 1. Social tagging of http://lre.eun.org open educational resources in the MELT Project Riina Vuorikari European Schoolnet
  2. 2. Social tagging of http://lre.eun.org open educational resources WHAT? Give me an example! - Let's look into bookmarks
  3. 3. Social tagging of http://lre.eun.org open educational resources And what is there for teachers? - Can it really help them to find digital resources?
  4. 4. Bookmarks  Readily available at your browser http://lre.eun.org  A good way to get back to what you once found  and organise your life according to folders..
  5. 5. .. if you remember in which folder it was stored in? http://lre.eun.org
  6. 6. Proliferation of web-based services for sharing digital items http://lre.eun.org
  7. 7. Proliferation of web-based services for sharing digital items http://lre.eun.org
  8. 8. ...times are changing http://lre.eun.org
  9. 9. Sharing digital items through tags and a tag cloud http://lre.eun.org
  10. 10. Cues and trails from other users http://lre.eun.org
  11. 11. Social tagging of resources in multilingual Europe  Addition to the traditional LOM http://lre.eun.org  By users interacting with the portal, resources and other users  Four main tools: – social bookmarking and tags in multiple languages – ratings of usefulness – pedagogical annotations (used in learning events) – levels of user engagement when interacting with the system (what is viewed, how many times,..)
  12. 12. Social bookmarking  To store, organise, share and search bookmarks of web pages. Keep found things http://lre.eun.org found!  Users organise bookmarks with informal tags (instead of the traditional folders)  Bookmarks are usually public and shared  Find like-minded users with similar interest.
  13. 13. What is a tag?  Metadata externally applied to an item http://lre.eun.org  Can be used for sorting or managing  A hook for aggregating  Provides identifier and/or description  Personal marker to help associate with the resource by partly Thomas Vander Wal
  14. 14. Bookmark is a triple (user, resource, {tags}) http://lre.eun.org
  15. 15. A great navigational aid to discover resources! http://lre.eun.org
  16. 16. http://lre.eun.org Digital traces to follow!
  17. 17. More ways for social navigation http://lre.eun.org Discover resources through tags in multiple languages
  18. 18. “Social” makes http://lre.eun.org trails visible.. by Stiphy
  19. 19. http://lre.eun.org and shows where to do go
  20. 20. Can tags and bookmarks be used to http://lre.eun.org connect users cross national and language borders?
  21. 21. Social bookmarking in multi-lingual environment http://lre.eun.org
  22. 22. .. allows new ways to discover both resources and people! http://lre.eun.org
  23. 23. “Travel well” learning resources  item bookmarked is of different language than user's mother tongue and/or http://lre.eun.org  item has tags in different language(s) than that of the item language and/or  item is from a different country than from where the user is from
  24. 24. Are tags found useful? http://lre.eun.org Vuorikari, R., Ochoa, X., Duval, E. Analysis of User Behavior on MultilingualTagging of Learning Resources. In Workshop proceedings of the EC-TEL conference: SIRTEL07 (EC-TEL ’07) (Crete, Greece, September 17-20, 2007)
  25. 25. Are tags found useful? http://lre.eun.org Tags, produced with no outlay, show an encouraging and potential gain in overall usefulness! Vuorikari, R., Ochoa, X., Duval, E. Analysis of User Behavior on MultilingualTagging of Learning Resources. In Workshop proceedings of the EC-TEL conference: SIRTEL07 (EC-TEL ’07) (Crete, Greece, September 17-20, 2007)
  26. 26. Does the language matter? http://lre.eun.org  Need for better ways to identify the language – Give rules (if the user first preferred languages is.., then..) – Automate the recognition of languages – Out-source it to users
  27. 27. “Travel well” tags  About 15% of tags contain a general term, a http://lre.eun.org name, place, etc. that is easily understood without translation  e.g. AIDS, software, EU, Euroopa, Europa, europe, Evropa, geograafia, Pythagoras, algebra, arhitektura, astronomie, Austrálie, bakterie, biotechnologie, dinozaurai, drama, formules, fotosyntéza, ..
  28. 28. What's the point of travel well tags?  If those tags need no translation or language http://lre.eun.org filtering to be understood, and  ..if they can be identified:  We can be sure to show at least some tags to users – whose language preferences we don't know, and – in whose language there are no tags or keywords available.
  29. 29. Benefits of social tagging and content enrichment http://lre.eun.org  Will offer a richer view on how resources are used (viewed, tagged, shared, used)  Who interacts with resources cross (inter)national and linguistic borders  How resources are taken up and how do users enrich your content
  30. 30. User engaging with resources Steps taken: - views page http://lre.eun.org - views metadata - bookmarks and tags - rates Shareable with others through Contextual Attention Metadata framework!
  31. 31. How do users tag?  Most posts consisted Percent of tags/posting of only one tag Onetag 79% 2 tags 15% http://lre.eun.org 3 tags 4% 4 tags 1% 5 tags 0.39%  More than half of 6 tags 0.23% tags were used just 7 tags 0.08% once (54%) No guided tagging in this  Only about 10% of pilot! tags were reused more than twise This may change.
  32. 32. Semantic analysis of tags  Factual tags 63% (Golder: item topics, kinds of item, category http://lre.eun.org refinements)  Subjective tags 29% ( Golder: item qualities)  Personal tags 3% (Golder: item ownership, self-reference, tasks organisation)  5% other  Sen et al. (2006).
  33. 33. Why tag categories?  In Sen et al. (2006) it was found that tags of different categories http://lre.eun.org can be useful for different tasks  In our case it is too early to say anything, but ...we'll have an eye on it!
  34. 34. Metadata LOM tags social bookmarks folksonomy social tagging multi-linguality social classification http://lre.eun.org thanks! for your attention learning resources user communities discover resources and items questions? teachers social navigation social traces paths, trails http://www.cs.kuleuven.ac.be/~hmdb/infovis/calibrate/calibrate.html flock
