Similarity Weighting Schemes for Collaborative Filtering

alan — Sun, 01 Apr 2012 10:48:11 +0000

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 [...]

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.

At UMAP I will be presenting a poster evaluating how certain demographic data affects [...]

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 [...]

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 [...]

Social networks and media consumption

A couple of weeks ago I noticed that the vast majority of my YouTube consumption came from links people in my Twitter, Facebook, etc. feeds posted to their timelines.

This got me thinking. How is our media consumption affected by our feeds (or our friends feeds actually)? Which types of media are affected more than [...]

RecoMMender Systems

If you’re reading this, you might have read my previous posts about RecSys2010, and in that case you might know that I had axtremely high expectations for this year’s RecSys conference, and I was not dissappointed.

The conference program had been extended from last year and now included two days of workshops: [...]

I’m in Barcelona, at a hotel a stone’s throw from Parc de la Ciutadella, getting ready for RecSys2010.

Arrived here yesterday and spent most of the day in my hotel room working on my slides for my presentation at the Doctoral Symposium tomorrow. Or at least, I planned on working on them. This being my [...]

RecSys2010

Just over a week to go till this year’s Recommender Systems conference and I must say I am really looking forward to it. Out of the (not very many) conferences I’ve been to (WSDM2009, RecSys2009, ECML-PKDD2009, IUI2010), last year’s RecSys was the one I enjoyed most (IUI being a very close runner up). [...]

Context-aware Movie Recommendation – CAMRa

alan — Mon, 09 Aug 2010 14:38:05 +0000

As I’ve written earlier, at this year’s RecSys we’re organizing a challenge on context-aware movie recommendation. The challenge is part of a joint event together with the workshop on Context-Aware Recommender Systems (CARS) and I’m anticipating both events to be very interesting.

We’re done with the reviewing and currently waiting for the camera ready versions [...]
