Multimedia Recommender Systems

Student Projects in Multimedia Recommender Systems

Contacts (if not stated otherwise): Markus Schedl,

These student projects can be started any time (including holidays) and can span over semester boundaries.

Remark: We are open for new proposals - if you are interested in Multimedia Recommender Systems, feel free to contact us!

 

Topics:

● Explainability and transparency of recommendations/recommender systems
● Fairness and bias in recommender systems (data bias, algorithmic bias, debiasing, etc.)
● Investigating bias of recommender systems algorithms
● Investigating bias of recommender systems datasets
● Graph embeddings for recommendation in online social networks (Markus Schedl)
● Session-aware music recommendation (Spotify Music Streaming Sessions Dataset)
● DNN-based music recommendation from implicit feedback data (LFM-1b Dataset)
● Psychology-informed recommender systems (cognition models, affect-aware, personality-aware systems), for instance, Implementing a personality-aware recommender system, according to, e.g.:
   ○ Hsin-Chang Yang, Zi-Rui Huang: Mining personality traits from social messages for game recommender systems. Knowl.-Based Syst. 165: 157-168 (2019)
   ○ Ifeoma Adaji, Czarina Sharmaine, Simone Debrowney, Kiemute Oyibo, Julita Vassileva: Personality Based Recipe Recommendation Using Recipe Network Graphs. HCI (14) 2018: 161-170
   ○ (personality-aware MF for implicit feedback data!) Ignacio Fernández-Tobías, Matthias Braunhofer, Mehdi Elahi, Francesco Ricci, Iván Cantador: Alleviating the new user problem in collaborative filtering by exploiting personality information. User Model. User-Adapt. Interact. 26(2-3): 221-255 (2016)
● Comparative study of context-aware music recommender approaches(e.g., comparison of various contextual prefiltering approaches to baseline):
   ○ Comparison of various contextual prefiltering approaches to baseline:
   ○ prefiltering on country-level, prefiltering on level urban/rural regions, prefiltering on combination of country and urban/rural level, baseline: no prefiltering (dataset of music tweets from ACMMM 2019 demo paper)

   ○ Other state-of-the-art methods
● Automatic playlist continuation (using DNNs); reimplementing approaches from:

● Investigating computational characteristics of music listening sessions and music playlists (what makes a good playlist?); based on the Million Playlist Dataset
● Investigating the perception of diversity and similarity in a set or sequence of recommendations
● Domain-specific recommender systems: music, point-of-interest, hotel/accommodation, jobs, fashion, etc.
