Frappé: Paper on arXiv & Context-Aware App Usage Dataset Release

During my last few months in Telefonica Research in 2013 I worked with wonderful colleagues and RecSys gurus Linas Baltrunas and Alexandros Karatzoglou along with scientific director Nuria Oliver on a context-aware mobile app recommendation service called Frappé. Frappé was specifically designed to support novel app discovery experiences. In order to assess it’s effectiveness we deployed Frappé in-the-wild on Google Play and ran a smaller-scale user study with 33 users designed to evaluate user perceptions of using and engaging with an app recommendation service.

Yes, it’s been a while since working on this specific project, however, I have 2 very exciting announcements to share about Frappé.

  • Firstly, a paper describing the Frappé application, our large-scale Google Play deployment and insights from our smaller scale user study has been published on arXiv. In particular we describe actionable lessons learned related to designing, deploying and evaluating mobile context-aware recommender systems in-the-wild with real users. Details and PDF are available here.
  • Secondly, we have released the anonymized Frappé data set!! It can be downloaded from Linas’s website HERE. The dataset contains 96,202 records by 957 users for 4,082 apps. We’re very excited to see what the RecSys and Mobile HCI communities end up doing with this rich dataset, in particular in terms of pushing the envelop in the context-aware recommender systems domain.

If you end up using the data, we ask that you please cite the following paper:
