Towards Interoperable Social Recommendation: Storing, Sharing, and Reusing Evaluations of Learning Objects

Abstract

Since the early days of the use of digital learning resources in teaching and learning, quality has played an important role, sometimes more implicitly than explicitly. In the domain of digital learning resources, a plethora of ways to evaluate learning resources exists. However, limited ways to share and reuse these evaluations for social information retrieval purposes currently exist. Social recommendation is based on the opinions of the members of a community, in order to help individuals in that community more effectively identify content of interest from a potentially overwhelming set of choices.

This chapter emphasises the importance that the representation and storage of user experiences and evaluations of learning resources has, as a means to support social recommendation, and help users search the Web for learning resources in an effective and efficient manner. Thus, this chapter proposes a scheme for storing results from learning resources’ evaluation in a structured and reusable way, so that they can be shared between social recommendation systems. More specifically, the chapter develops an Evaluation Learning Object Metadata (evaLOM) model, a metadata schema that allows the description of the evaluation method used for learning resources, as well as storing its evaluation results. This model is part of a larger specification called Learning Object Log Specification (LO Log).

Weekly PhD Report 06, week 1

work done:

• Started an extensive review on recommendation systems, especially looking for papers on LORs and social networks
• I'm looking especially design requirement and needs for LO recommender system, but interested in dilemmas found in the field and open questions such as what would the benefit of having a distributed service over a centralised one, etc.
  
• Worked on the book chapter on LORs that I sent you a while ago.
• Worked on a plan for the year and looked into some possible collaboration paths with people, namely picked up on an idea to write something with David Tosh from ELGG.
• Tried to revitalise the plan for NING developments in vain

• work on a plan to run a pilot on Ning
• keep up the good spirit

Weekly PhD Report 51-52

• Spent time writing a part for a paper "An Overview of Learning Object Repositories" with Argiris Tzikopoulos, Nikos Manouselis. Argis has made a survey on 59 repositories, and I was asked to help writing a part of it. I wish to send you this paper for comments later this week.
• Worked on a proposal for a book chapter which would be called "Towards Interoperable Social Recommendation: Storing, Sharing, and Reusing Evaluations of Learning Objects". The idea would contribute to Jehad&all's Log specifications. This would also be used for recommendation purposes. See the attachment for more information.
• currently reading lots of papers related to this, see: http://www.furl.net/members/vuorikari/LOR and
  http://www.furl.net/members/vuorikari/recommendation
• Played around with swicki, see: http://riina1-swicki.eurekster.com/
  • Swickis are community search engines that learn from users
    
    
• Checked out http://digg.com, the new hot tool for the community to review news. This is an interesting post about Digg and some other relevant social software.
  http://thomashawk.com/2006/01/digg-delicious-kaboodle-and-wink.html
• The kick in Digg is that when you submit a link there, it will be Dugg [imperfect] by other news readers. As soon as one post starts getting Diggs on it, i.e. it is read by many other who think it's relevant, it will climb higher up on the relevance ranking list, thus appear on the front page of the Digg.
  
• Worked on Ning.com application on social recommendation with Julien, Ben and Bram. We were not able to make it search Ariadne yet, but should be feasible soon.
• The issues seems to be that we added our, well, Julien's own SOAP library to make the connection. However, the Amazon services module in Ning is pure PHP running in the Playground, as are the modules that use other web services (such as Flickr and Gmail). they said "You should be able to make external HTTP requests from Ning just fine, whether using curl or PEAR's HTTP::Client (both of which we support)." Hmmm...

10 Web Trends That Should Die in 2006

Yeah, there are so many good points. Things that I've been thinking about too, like spliting up the article (it is just so much easier to scrol down, don't you understand?), tiny font, etc.

One thing I would like to see on this type of a list is "Create the entire navigation menu in Flash". It is so last millennium, but people still keep doing it! I hate it, especailly because I don't have Flash installed in my default browser (I'm tired of seeing things and adds flying around on my screen). Many times those Flash navigation menus don't give any alternatives, thus I'm not even able to see the whole site. Dah, get over this, people!!

Weekly PhD Report 49

Things done last week:

Unfortunately not much dedicated PhD work got done last week apart from some interesting encounters with researchers and practitioners attending the same event as I did, e.g. EduExchange in the NL http://eduexchange.kennisnet.nl/ and Eminent http://eminent.eun.org.

A few interesting leads I gathered: Networks seems to be popping up everywhere. Of course, not on the official agenda, but during the coffee brake discussions and dinner, etc. Many prominent e-learning researchers and practitioners dig the idea of bottom-up approach, thus social network analyses and social recommendations are being mentioned more and more.

Some interesting people I talked with:

• OUNL seems to be working also on social recommendation in the context of peer tutoring and a new EU project called tenCompetences. If interested check http://dspace.ou.nl/ for names such as R.Kopper, P.Slop and C.Tattersall.
  
  
• Had a chat with The Open University UK researcher R.mcCormick about how LOs are used by people and some ideas of looking at different links between the users and usage. This was interesting as I've thought about making similar analysis of the use of LOs once I get my experiment going with Ning.com.
  
• I thought it would be interesting in looking for hubs (influential people) in distribution of LOs through social recommendations and social/collaborative browsing. McCormick suggested that if any are found, it would be interesting to classify different types of connections that there are in this type of social network. That could help us better understand the nature of take-up of some LOs and some not, etc.
  

• Ulla Gjorling from UNI-C had done a study on the localisation of LOs within a project called eColors lead by EUN. They also made some recommendations for the ease of localisation. One of the outcomes was that producers rarely think about localisation, but it should be thought of while at the design and production phase, not later. Examples, translating some Flash files is labor intensive, but much easier if the text is inserted in an xml-file instead of within.
  
• This made me think that FOSS approach for ease of localisation should be adapted also for LOs, keep text separate from the code. Also, eColors talked about special localisation expertiece centers in Europe. They could use some SourceForge type of tools to make their job easier. This probably will be further investigate in a future project to enhance cross-boarder collaboration of LOs.

• Chatted up with James Simon from SUN who told me about SUN's involvement in Hypercomputing (not super computing anymore?..). They are about to build one with Japanese AMD and wish to get up on the ranking about the fastest computers. Cool to know people like that! I also mulled over my PhD work a bit with him to get some validation for the idea. He seem to think it was important.
  
  
• Quality of learning resources seems to be popping up in every country in Europe. The leading work is done by BECTA, UK and the National Board of Education in Finland (both about to finalise: see insight.eun.org/dossiers).
  
• Also, Poland, Switzerland, Hungary, Italy (INDIRE), Slovakia have work in planned/in progress. A lot of synergies can be picked up and one plan is to make a peer review process of UK and Fi work to see what aspects of work can be transfered to European level, and what is laterally transferable from one country to another.
  
  
• Galvin Conor from UCD Dublin sat next to me during dinner. We talked about academic research, PhDs, Summer Schools and such. He recommended me one Summer School, but I seem to have forgotten it. We also talked about networks and how ideas spread out. Too bad that I can't recite all the important things that were said, but the Eifel tower cruise on a boat was great!

Voila quoi, that was my week.

The Top 20 Edu Blogs

Where's Glenn?: 11/21 - 11/25: "BlogThis!"

Ok, one of those blogger guys again, sigh, who put their picture in the front, side bar and everywhere. Makes me really wonder what is this blogging really about..?

Anyway, he's put up a list of the Top 20 educational blogs. Some names that I read regularly, some more sporadically, some I don't even know. Pretty anglo-saxon, though..

A few words about the open source for education in Europe conference

You can find the whole posting at the link. It was FUN! The picture about me does not work on the blog posting, but here it is again.

I'm frustrated about blogging, it takes so much time! And I don't seem to understand what the trackback is about :( Yeah, and then all these postings in different blogs just kill me. There! It feels better ones it's out!

Weekly PhD report week 42

Things I've done on week 42:

• Attended EUN Policy Innovation Meeting about quality in e-learning
• Presented the EUN framework on quality of learning resources based on the paper that I co-wrote with Frans Van Assche
• Attended Xchange 2005 meeting in Brimingham

testing, no time to write this week,

nor week before for that matter...

Been in Birmingham for Xchange 2005 and tomorrow going to Cambridge for eP Plugfest and Europortfolio 2005.EPICC project

Weekly PhD report week 40

things done last week:

• attended the HMDB seminar (Jehad's presentation)
• worked for 2 days on EUN's new concepts for learning resources repository where my brainstorming contributed for ideas in the area of social networking and evaluation of learning resources.
• The idea of "school bag" was conceived. The "school bag" would do what social bookmarks do on the web; it would be a place where users can create their logs of the learning resources they have used (with some evaluation and "MyTeachingIdea") and also bookmarks on interesting resources within repository ("keep found things found") that the user can use in a later occasion. The bookmarks could, for example, be used by a teacher to create a ready-selected lists of learning resources for learners in a given subject. Furthermore, the idea is that schoolbag could be managed by using tags as labels. Furthermore, the schoolbag would be used as a base for recommendations, but also would allow social navigation.
  
  
• How to integrate social bookmarking services as we know them now on
  the web into acquisition of learning resources within a LOR
• Worked on the concept of future work in the area of quality in e-learning in-learning and checked any work in Prolearn
  
• Worked on a paper for Open source in European education
• Started a new blog hosted in KUL. Not many things there yet: http://ariadne.cs.kuleuven.be/wordpress/rvuorikari/
• btw; I post these activity reports on my other blog where you can get feeds from here: http://feeds.feedburner.com/smallThingsConsideredByRvuorikari
  
  
  

things to be done this week:

• Work on the ped.part of the workshop for ICRAF workshop
• Conduct business as usual

Weekly PhD report: Week 39

• Attended ICL 05 in Villach and presented a paper in a workshop called "Can personal digital knowledge artefacts' management and social networks enhance learning?"
• had some feedback from different people which was valuable for me

• Thought about how to use the lifecycle of LOs to assure better targeted quality (i.e. fit for purpose) through a Multi-attribute recommender or something.
• the idea would be to define criteria that represents important qualities of each lifecycle ("whenever I search I want my LOs to have the pedagogical metadata included"; "whenever I search I only want LOs that have been evaluated by other users",..)
• user could define what do they find important or this could also be extracted automatically based on previous searches logged; phase one is not important to me, phase 2 is important, etc.
• this would be saved and/or redefined with each search
• system would render only replies fitting to this criteria
• this profile could also be for ranking and personalising the search results.
  

Things I plan to do this week:

• keep on thinking and reading and re-visiting my research plan

Weekly PhD report: Week 38

• Thought about how to harness the power of social bookmarking in the context of a LOR. This is related to my research question about recommendation system based on social networking, but also to an initial problem within EUN's repository:
• Many resources used by teachers are links to webpages. Teachers don't feel like adding them into a repository. If they are encouraged to use social bookmarking tools on the web, how could we make sure that the resources can be re-used in our LOR?
• What service to use? If use delicious, for instance, should the date be left on their server and use an API to integrate it into EUN's services? Or should the data be entered into our repository - incompatibility of the elements. some analysis of a few bookmark exports in a table of the attachment
• Also, how could the social part of collaborative filtering be taken advantage of in the context of a LOR?
• Social bookmarks on the Web are what a "shopping basket" (integrated in CELEBRATE, teachers could bookmark LOs that they found interesting for later use) is for a LOR.
• A memo about the initial research questions in this context as attachment.
• on-going thinking
  
  
• Reading "Linked" by Barabazi.
  
• Made my think whether the links between social bookmarks and their users should be analysed and maybe visualised and if yes, for what reason.
  
• Some discussions about this with Joris and Nikos (from KHT).
• on-going thinking
  
  
• Worked on my ICL presentation: Thought about a classification for end-user authoring tools on the Web 2.0:
• Webpublishing tools: weblogs and wikis
• Content syndication tools: Webfeeds'readers (RSS, Atom, ..)
• Tracking services: Technorati, and what's after that?
• Artefacts' management and social networking: Flickr, Delicious,
• hybrid services combining parts of above.
  
  
• Read and thought about Web 2.0 and found these images very inspiring:
• Tim O'Reily (yes, he's got a Flickr account) http://www.flickr.com/photos/36521959321@N01/44349798/
• Alex Barnett http://www.extremepodcasting.com/extremeimages/web2.0_enabled_content_small.jpg
  
  
• Contributed in co-writing a proposal for a chapter "An Overview of Learning Object Repositories" for a book called “Learning Objects for Instruction: Design and Evaluation” with some old project partners from
  

Informatics Laboratory
Division of Informatics, Mathematics & Statistics
Dept. of Science, Agricultural University of Athens, Greece

• As a part of an eContent project they have done a review of 59 LOR, but their main focus is on agri-topics.

• Finalised a co-authored paper for Europortfolio 2005 on "National policies and case studies on the use of portfolios in teacher training"
  
  
• Drafted a paper for Open Source for Education in Europe called "Open Content and Source: European Schoolnet Riding the Wave"

Weblogs, Wikis, Webfeeds... and the educational technology research community

Ok, my new study buddy Seb, whom I met in the infamous ProLearn SSC 2005 (images tell more than those dusty words: do you see us working hard? not, 'cause SC stands for School + Conference, what good can come out of that, but the coffee-breaks..), was asking questions to himself out loud, so I thought I'll give it a thought too. He goes on about our SSC and then concludes with a rhetoric question mark:

If even some up and coming educational technology researchers have not yet embraced distributed Webpublishing practices to support their own networking efforts, we should be very careful celebrating yet another disruptive technology for education?

I do agree to some extent, but for me the question is rather "Disruptive or Distractive technology"? We do things the way we are used to doing them to save us time, in many cases, from learning new things. You know how that learning can be annoying, you might feel frustrated, dumb, faced with new challenges like using a new GUI, hit wrong buttons, loose all the text without saving it - and all this just to share a few little memories with your new friends, of whom you don't even remember the last name in any case.

Hmm.. I know I'm pushing it, but really, I think all forms of webpublishing should still be made easier and part of the stuff that we usually do, like sending mails, for example. [Now, I guess that is already done, so I should come up with something more productive..]

I truly feel that some people are distracted for different reasons by the "disruptive" (hate that word) technologies such as weblogs, wikis, and Webfeeds. I personally still have a problem with posting on a blog (but I love the other stuff), and I'm trying to reflect upon it to better understad what is going on. I think there should be more studies done about the poeple who find learning through this type of activities compelling just like we can say that people have different learning styles; some like learning by doing whereas others like textual content and so on. Maybe blogs are really good for the learners who have a preference for textual bases, whereas for some with dyslexia it can be a pretty disturbing experience.. [Which philosopher was is that back in a day didn't even think writing was such a good way to pass on teaching as opposed to discussing?]

I think with new technologies and solutions that they bring along for learning we should just accept the fact that there is no solution that fits all. With fairly easy design solutions we should be able to offer a variety of tools to learners that satisfy their style of learning, and not only the way that I think they should learn. In my opinion there's room for everyone and, the good thing is that today we can afford to offer different solutions and tastes.

However, I do regognise that there is also always room for improvement of the old ways of doing it...just to mention "Cornfolios"...

Chaqu'un son truck!

- Prolearn Summer School 2005
Originally uploaded by sebastian fiedler.

This was about the best session at the ProLearn Summer School Conference 2005 in Sile, Turkey. Note the fancy name, I call it a conference and school. what a pitty, a really nice opportunity wasted with silly organisation of lectures for five days straight.

My research idea in short, very short...

My interest for my PhD work is in the area of advisory models or recommendation models for learning resources in the context of a repository, and possibly also extensible of a LCMS, VLE, etc.

I currently plan to look at the 3 different models based on:
- user modeling like Amazon,
- social networking models
- evaluation criteria

The idea, most of all, relies on the fact that metadata as we used to know it (one time entry) in the context of a repository has to change; it will become more dynamic, and contain more information about the user and its actual usage.

First of all, I have to look at different advisory models that are used, and that could be applicable to the field of education. It's clear that some models used in commerce, say, might work, but not all. Education, after all, has different goals and ones very specific to it (not only to learn skills and competencies, but also higher-oder cognitive skills).

I also will have to look at the metadata and think what fields would be important for this type of data, etc.

Second, I would design a conceptual model for these different models that I come up with.

Then I have pilots with real users, hopefully from different educational communities. It would be interesting to find out whether different communities have preferences for one model or another, whether those models could better work as stand-alone or part of the same system where user could choose the one they prefer or with combining parts from here and there. and so on....
