The 9th ACM Conference on Recommender Systems is the premier international forum for the presentation of new research results, systems and techniques in the broad field of recommender systems. With three accepted publications, the Know-Center shows a strong presence at one of the most important conferences regarding recommender systems research.

Taking place in Vienna, Austria from September 16 – 20, 2015, the 9th ACM Conference on Recommender Systems (RecSys 2015) conference brings together the main international research groups working on recommender systems, along with many of the world’s leading e-commerce companies, it has become the most important annual conference for the presentation and discussion of recommender systems research.

Know-Center’s Social Computing Area, represented by Emanuel Lacić, Dominik Kowald and Matthias Traub will present three publications at RecSys 2015:

  •  “Tackling Cold-Start Users in Recommender Systems with Indoor Positioning Systems
    This publication presents work-in-progress on a recommender system based on Collaborative Filtering that exploits location information gathered by indoor positioning systems. This approach allows us to provide recommendations for “extreme” cold-start users with absolutely no item interaction data available. The presented work was funded within the Learning Layers EU research project.
    The paper is available for download here.
  •  Evaluating Tag Recommender Algorithms in Real-World Folksonomies: A Comparative Study”
    The goal of this study is to provide researchers and developers of tag-based recommender systems with an extensive, transparent and reproducible evaluation of state-of-the-art tag recommender algorithms in real-world folksonomies. The presented work was funded within the Learning Layers EU research project.
    The paper is available for download here.
  • ScaR: Towards a Real-Time Recommender Framework Following the Microservices Architecture
    This publication presents an effective scalable recommender framework termed ScaR. The framework is based on the microservices architecture and exploits search technology to provide real-time recommendations. The presented work was funded within the Learning Layers EU research project.
