Media recommender systems have been one of the flagbearers for the turn towards using personal data to enhance media experiences. From collaborative filtering and content-based recommenders, to demographic, knowledge based, context aware and social recommenders – the variety is diverse.
While this shift towards data-centred recommendations are often seen in a positive light, it also introduces a number of social and technical challenges around the use of personal data, which warrant attention.
Here, trust, privacy, transparency, control and accountability are highlighted as challenges to be considered. These challenges are further unpacked in detail in other research exposure, bias, and sabotage (Lam, Frankowski and Riedl, 2006), legal, social and ethical (Sailaja et al., 2018), filter bubbles and echo chambers (Sailaja et al., 2019) and multi-dimensional accountability concerns (Sailaja, 2020).
Hence, there is the opportunity for further exploration of design responses that speak to these challenges, thus helping alleviate them. Research has highlighted the effectiveness of a ‘data dialogue’ – the possibility of an ongoing conversation around data through the use of the service – (Sailaja, 2020) in this context. However, a tangible version of this ‘data dialogue’ for a media recommender is yet to be realised. Our project will explore this opportunity by studying the possibility of using design in the making of effective audience ‘data dialogues’ within media recommenders.
The research uses a new prototype of a media content discovery service built on a personal data store that allows the user to ‘link’ ( import copies of ) their media profiles and associated data (e.g., viewing history, playlists) from different digital media platforms such as Spotify, Instagram and BBC. This allows them to create and control their own combined media profile to retrieve recommendations based on their personal media interests across different digital media platforms.
In line with our long standing partnership with BBC R&D – which previously explored the idea of including a Personal Data Store similar to that of the DataBox (Amar, Haddadi and Mortier, 2016) to produce design interventions, such as the BBC Box and the Living Room of the Future – this project includes the principles of HDI. HDI is an interdisciplinary, emergent sub-domain that derives inspiration from multiple disciplines to devise data sensitive responses within technologies through three core values: legibility, negotiability and agency. The project realises these HDI principles through the use of the Personal Data Store and other accompanying design decisions.
While the findings are primarily expected to contribute to the future design of data legibility and negotiability into media recommenders, they would also be significant to research in a variety of other domains working on the design and adaptation of next generation services that use Personal Data Stores.
