On August 19th we will be organizing the first Amsterdam Recommender Meetup. The meetup will be hosted by CWI and will feature a few (2-3) talks by recommender system practitioners describing problems/solutions related to data, recommendation, interaction, etc. they deal with in their systems.
The event, which hopefully will become a recurring thing, is in the same spirit as the Recommender Stammtisch that we kicked off last year in Berlin.
The main idea is to bring together practitioners, researchers, hobbyists and generally anyone who is interested in recommender systems specifically, or user-oriented data mining generally.
