    Recommender Systems

    The DMIR group develops new methods to recommend items to users to enhance their overall user experience in a variety of application scenarios. For example, we help users to find relevant products to buy or users of our social bookmarking system BibSonomy to annotate websites and publication with keywords (tags). In this context we leverage various information like navigation paths, user behavior or buying behavior. We utilize different machine learning algorithms, including deep learning, for our recommendation methods. To validate some of our methods, we can deploy and test our methods in our live system BibSonomy, which is run and developed by the DMIR Group.

    Projects

    We are currently working on the following projects:

    adidas

    We are analysing the user behavior in the Adidas web shop to improve item recommendations.

    BibSonomy

    The social bookmarking system, that enables us to test our new recommendation methods.
