LifeSoundTrack: música, tecnología, recuerdos y alzheimer / music, technology, memories and alzheimer

English version below!

A veces los proyectos más enriquecedores son los que realizas con menos recursos.

En éste proyecto utilizamos las tecnologías de recuperación de la información musical para encontrar la banda sonora de la vida de personas mayores españolas. Ésto ha presentado varios retos de investigación y tecnológicos. En concreto hemos podido observar el sesgo de los sistemas actuales de recomendación musical tanto en que sólo se centran en un repertorio musical popular y sus interfaces y descriptores musicales están pensados para usuarios jóvenes. Esto aplica a:

  • Las taxonomías de géneros musicales.
  • Los idiomas predominantes en las canciones y su etiquetado.
  • Los descriptores y playlists que se utilizan (e.g. música de fiesta).
  • La dificultad para tener los derechos de dar una canción a éstas personas para que la escuchen.
  • La dificultad de tener dispositivos fáciles de usar y dirigidos a éste tipo de personas.

Por tanto casi hemos tenido que empezar desde cero! Éste es el repositorio github que hemos creado (abierto): https://github.com/MTG/lifesoundtrack

Y si alguien quiere obtener su banda sonora puede hacerlo en bandasonoravital.upf.edu 

Atención! El sistema está pensado para personas mayores que han nacido o viven en España, por lo que utilizadlo sobre todo si cumplís éstos requisitos o para alguna persona que conozcáis que los cumpla.

Ha sido un privilegio poder colaborar con la Fundación Pasqual Maragall, La Fundación AVAN y la Escuela La Salud de Sabadell en éste piloto con personas que padecen la enfermedad de Alzheimer. Sobre todo ha sido genial trabajar con Nina, Anna, Carolina, y los chicos de La Salut. Aquí podéis ver un vídeo que me encanta y resume muy bien el proyecto:

Para más información no os perdáis el documental Sense Ficció que emitirá TV3 el día 8 de Mayo por la noche!!!

Más información del proyecto en la web del MTG y de la Fundación Pasqual Maragall.

Y las bandas sonoras se pueden generar en http://bandasonoravital.upf.edu/ 

¡Gracias a todo el equipo! En especial al grupo del MTG: Perfe Herrera, Felipe Navarro, Olga Slizovskaia, por su tiempo en éste proyecto donde no hemos tenido financiación específica.

Sometimes the most enriching projects are those that you do with less resources and funding.

In this project we use music information retrieval (MIR) technologies to find the life soundtrack of Spanish elderly people. Starting from a questionnaire where we ask about biographical information and one´s relationship with music, we build a playlist looking at several sources such as spotify or youtube. 

This has presented several research and technological challenges. Specifically, we have been able to observe the bias of current music recommendation systems, as they focus on a popular musical repertoire and their interfaces and musical descriptors are designed for young users. This applies to:

  • The taxonomies of musical genres.
  • The predominant languages ​​in the songs and their labeling.
  • The descriptors and playlists that are used (e.g., what does happy music mean).
  • The difficulty to have the rights to give a song to these people to be heard.
  • The difficulty of having easy-to-use devices aimed at this type of person.

Therefore we almost had to start from scratch! This is the github repository that we have created (open): https://github.com/MTG/lifesoundtrack 

And if someone wants to get their soundtrack you can do it at bandasonoravital.upf.edu
Attention! The system is designed for seniors who have been born or live in Spain, so use it especially if you meet these requirements or for someone you know who complies.

It has been a privilege to be able to collaborate with the Pasqual Maragall Foundation, the AVAN Foundation and the Health School of Sabadell in this pilot with people suffering from Alzheimer’s disease. Above all it has been great to work with Nina, Anna, Carolina, and the guys from La Salut. Here you can see a video that I love and sums up the project very well:

For more information, do not miss the Sense Ficció documentary that will broadcast TV3 on May 8 at night !!!

Paper on “My musical avatar”

We feel ourselves identified with the type of music we like and we sometimes use music to define our personality. I guess one of the questions I ask to any new person I know is “whad kind of music do you listen to?”.

During the last few years, I have been taking part in a research project, where the main goal is to visualize one’s musical preferences, “The Musical Avatar“. The idea behind is to use computational tools to automatically describe your music (in audio format) in terms of melody, instrumentation, rhythm, etc and use this information to build an iconic representation of one’s musical preferences and to recommend you new music. All the system is only based on content description, i.e. on the signal itself and not on information about the music (context) as found on web sites, etc. And it works! 🙂

We finally published a paper describing the technology behind and its scientific evaluation   at Information Processing & Management journal. This is the complete reference:

Dmitry Bogdanov, Martín Haro, Ferdinand Fuhrmann, Anna Xambó, Emilia Gómez, Perfecto Herrera Semantic audio content-based music recommendation and visualization based on user preference examples. Information Processing & Management
Volume 49, Issue 1, pp. 13-33, January 2013

There is much to improve, but you can see my musical avatar below. Can you guess how my favorite music sounds like? You can of course build yours from your last-FM profile here.

Highlights

► We propose preference elicitation technique based on explicit preference examples. ► We study audio-based approaches to music recommendation and preference visualization. ► Approaches based on semantics inferred from audio surpass low-level timbre methods. ► Such approaches are close to metadata-based system being suitable for music discovery. ► Proposed visualization captures the core musical preferences of the participants.

Book on Multimodal Music Processing

I’m very happy to have coauthored a chapter in this book on Multimodal Music Processing, as a result of a seminar that Meinard Muëller, Masataka Goto and Simon Dixon organized last year.

I contributed to a chapter about user modeling and personalization, which I think it’s a key aspect of future MIR systems. Searches, descriptors, similarity measures and classification algorithms should be adapted to different user needs, in order to provide powerful and informative services of recommendation and retrieval.

I hope you will find it interesting!
