Example of multilingual searchfor learning resources

Why should I discover learningresources across countries?
www.europeanschoolnet.org
Discovering learning resources across language boundaries is challenging!
Main problem: the resource & its metadata description are madein a different context from where the resource is discovered
and/or actually used
Problem statement
www.europeanschoolnet.org
Tried Google for multilinguallearning resources?

What do we know from theliterature reivew?
Mukherjee, R., & Mao, J. (2004). Enterprise Search: Tough Stuff• Why searching intranet is so much harder than
searching the Web? Content is oftentimes notcross-referenced and lack the typical link-structure of the Internet
Halavais, A. (2000). National borders on the World Wide Web• Web sites in most cases are more likely to link to
another site hosted in the same country than tocross national borders
Berendt, B., & Kralish, A. (2009)• Show that the smaller the language is, the smaller
the relative percentage of in-links is

Learning resources from
different countries and
in different languages rarely cross-reference via hyperlinks!

The Economist (Sep 2nd 2010)• “People are online what they are offline:
divided, and slow to build bridges.”• This seems to be the case for commerce,
news and social networks!
www.europeanschoolnet.org
But «social web» for sure haschanged something?
“Sure, the web connects the globe,
but most of us end up hearing mainly
from people just like ourselves.”
www.europeanschoolnet.org
The Economist (Sep 2nd 2010)• “People are online what they are offline: divided, and
slow to build bridges.”• This seems to be the case for commerce, news and
social networks!
Zuckerman on Google data, 50 top websites in 30 countries• Almost every country reads all but 5% of its news from
domestic sources
Zuckerman on “Peace on Facebook”• Only 1-2% of the combined total of friendships on
Israeli and Palestinian accounts. For Greece andTurkey, his estimate was 0.1%
But «social web» for sure haschanged something?

John Kelly (Morningside Analytics) examined linksbetween blogs and twitter accounts in India andPakistan
• Discovered two hubs that link the twocountries:• South Asian expats in London link freely
to each other and to their home countries.• And cricket fans in both countries link up
spontaneously.
But «social web» for sure haschanged something?

dataTEL (under Stellar)
• Dataset challenge in the TEL context• http://www.teleurope.eu/pg/groups/9405/data

• Aim: challenges around domain specificdatasets– formal education dataset,
– an informal education dataset,
– mixture of both
• un-conference stylein Barcelona,– RecSys 2010

• Context = country, language, educational system,
curriculum...
• We have gained understanding that some content is
more useful than other..
• e.g. science, cross-curriculum
topics, language learning
eQnet: Can resources be used acrosscontexts?

Where to find « travel well » attributes?
2. Easyness to find theresource
(e.g. metadata & searchability)
4. Actual use of resources(e.g. evidence that LO is used in
different contexts)
1. Creating resources(e.g. visual, easy translation,
language independent,..)
3. Selecting « travel well »resources
(e.g. personal choice vs. basedon criteria)
Gut feeling?
