Question

Hello
Do anyone have an experience in recommender systems in online learning?

Answer 1

Hi can you let us know yoou are looking for a good online learning system?

Answer 2

I am a PhD student and I am concentrate on learning using social networks, so I am digging in reading about recommender systems that exploit the social relationships to recommend better learning resources or better people to answer my questions.
do OpenStudy use recommendation to recommend to us some people who may answer our questions or have better experience? (for example)

Answer 3

I'm afraid we don't use any recommendation systems at the moment, so I haven't looked into the matter too deep :/ There might be some useful information in the original Aardvark paper, The Anatomy of a Large-Scale Social Search Engine: http://kamvar.org/assets/papers/aardvark.pdf

Answer 4

I'm a masters student looking at a similar area. You might want to look into folksonomies and collaborative tagging systems tied to recommendation systems. There are more studies in this area. I recommend looking at work by a guy named david bamman he's the guy behind lexicalist.com . He works on lexical trends and predictions. The same thinking can be applied to social reccomenders.
As far as engines go I'd suggest the SOLR indexing engine but it would need to be interfaced with your social network and weight data. This does work especially if you put priority on a designated social groups( class mates) responses vs general public (an entire university).

Search engines/ reccomender engine groups that are very kind to researchers (they have allowed me to collect data in the past) are delicious, reddit, and blekko.

I focus on the searching habits and interfaces in my research. Here's the citation link if you are interested.

Answer 5

Wow awesome. Thanks for the info, it could prove useful for OpenStudy itself as well :)

What do you think of Elastic Search compared to solr, if they are comparable?

Answer 6

Its funny that you ask about Elastic Search. I've never used it but I've heard some good things about it. I'd say that its pretty comparable but SOLR is more geared towards an enterprise setup in my opinion. Its also built on top of lucene so its very similar to Elastic search.
