RecSys 2007

Tuesday, October 23rd, 2007

I just came back from RecSys ’07, and it was quite an experience. The great thing about the conference was the balance between academic and industry representatives. Researchers from around the world and representatives from some of the most well known recommender systems out there (Amazon, Netflix, MyStrands, etc).. teaching each other that even after a near decade of research, our understanding of recommender systems is only at it’s beginning.

Shopping Social Networks by ebay

Thursday, October 11th, 2007

Social Networks are expanding in all areas, so why not also in the shopping field?

Ebay took advantage of the new trend and has just created more than 600 social Networks with the name “Neighborhoods”, which are focused around a central product or topic theme like ‘iphone’ , ‘star wars’, even ‘coffee lovers’ (The latter seems to be the most popular so far with 453 members). By this way sellers and buyers come together and can exchange opinions, recommendations, stories. More info on the subject at the TechCrunch site

Hands-on Education

Wednesday, October 10th, 2007

The GroupLens blog mentioned something I found very interesting; a Google/IBM partnership is offering university students (from a select number of universities) the chance to develop software for large-scale distributed systems. They will be offering students access to lots of dedicated clusters. The website even offers sample content to help lecturers develop their courses! There is also some stuff on web security. Maybe sometime soon this opportunity will come across the Atlantic..

Facebook and the Long Tail

Monday, October 8th, 2007

In previous posts we were discussing the long-tailed characteristic of music, books, and other physical items. It now seems that this characteristic is also applicable to facebook apps:

An incomplete list of social bookmarking sites…

Friday, October 5th, 2007

When I was searching the IEEE Computer Society site for some research articles, I noticed a recent change: besides the traditional presentation of title, author, abstract, DOI, etc., now it is able to bookmark it with a third party social bookmarking site. Since it is quite interesting, I compiled an incomplete list of social bookmarking sites where you may want to have a try as well: (more…)

Artwork Recommenders

Thursday, October 4th, 2007

A recent email on the user-modeling email list is the Artwork Recommender that you can find here. After answering a short questionnaire, you can rate artwork from 1-5 stars, corresponding to “I hate this artwork” to “I like this artwork very much.” Being no artwork expert, I found my ratings of things to be quite biased towards the high end (3/4 stars) – it’s much more difficult to rate artwork than it is to rate movies or songs! They even have the option of saying that you are not interested in a piece of artwork at all, but I never felt like clicking it. Maybe this highlights the difficulty of finding good recommendations: understanding a rating process that users themselves don’t understand. You can also both give an overall rating for items and also rate a particular item in terms of its attributes (artist/material/style).

The website, though, has a neat interface (watch the paintings you rate “fly” into your profile history) and they are looking for participants to add to their dataset, so if you have 5 minutes then go in and rate some 20 or so paintings, help them, and see what comes out…
