The number of participants was more than 55,000 in this year at the International Broadcasting Convention (September 11-16, Amsterdam), the biggest event for the digital media and content industry. The CrowdRec project published a paper entitled “Comparative Evaluation of Recommendation Systems for Digital Media” that introduces the reference framework and its use case for the players of the digital media.

CrowdRec was represented by Domonkos Tikk (Gravity) and Moviri. The paper was assigned to the session “New consumer trends – the rise of social media and second screen technologies”, and there was interesting discussion among attendees and presenters on the CrowdRec concept of an impartial evaluation framework.


CrowdRec Workshop at ACM RecSys 2013

Workshop on Crowdsourcing and Human Computation for Recommender Systems Co-located with ACM RecSys 2013

October 12th, 2013, Hong Kong, China

We are pleased to announce that the first workshop was on crowdsourcing and human computation for recommender systems. The recommender systems we refer to as a broad spectrum of applications involving recommendation, information valuation, filtering, summarization, etc. in various contexts from e-commerce to social networking and mobile applications.

This workshop aimed at to providing a scholarly venue for researchers and practitioners to exchange the advances of crowdsourcing and human computation technologies and applications, with an emphasis on the applications in recommendation systems. The potentials and advantages of crowdsourcing and human computation have been explored for a number of areas such as computer-human interaction and information retrieval, we believe that these advances can also benefit the research of recommender systems at large.
