Similarity Weighting Schemes for Collaborative Filtering

Recently I presented a paper on the effects of similarity weighting schemes on collaborative filtering recommender systems at the 27th ACM Symposium on Applied Computing, more specificall in the Track on Trust, Reputation, Evidence and Collaborative Know-How.

I received a few questions about the presentation, this post aims at answering some of them, and provide a short summary of the paper.

2nd Workshop on Context-awareness in Retrieval and Recommendation

Last week we got notification from the IUI workshop chairs that our project proposal for the 2nd Workshop on Context-awareness in Retrieval and Recommendation had been accepted to the 2012 Intelligent User Interfaces Conference.

This year the organising team consists of Ernesto De Luca, Matthias Böhmer, Ed Chi and myself.

We’re hoping to attract a little more interest from the UI/UX communities this year as a large portion of the discussion at last year’s workshop was about these topics.

UMAP2011 and IJCAI2011

I’m currently preparing myself for two weeks of Catalan sun, first in Girona for UMAP2011 and then another week in Barcelona for IJCAI2011. Not having been to either of these conferences before, I am (needless to say) quite excited.

The Filmtipset dataset

I’ve recently noticed a significant increase in visitors finding they’re way here by googling for the filmtipset dataset, so I thought I’d post a descriptive text for those of you looking for it.

Sadly I must inform that the Filmtipset dataset is NOT available for download, nor has it ever been (more or less). Fimtipset have never offered their dataset for download.

Challenge on Context-aware Movie Recommendation 2011

It’s official since a couple of minutes, there will be a 2nd Challenge on Context-aware Movie Recommendation at RecSys2011.

Needless to say we’re excited. The focus this year will be a bit different from last year’s CAMRa, we’re aiming at a social context this year which will include household information. We’re working on a website which should be available soon at CAMRa2011.

This year we’re teaming up with Moviepilot again and will be releasing another batch of interesting datasets.
