2007:Discussion Points Euro MIREX Meeting

Welcome

This page is open to all folks interested in helping to set the agenda for the Euro MIREX Planning Meeting (22-23 April, 2007). This includes meeting participants and anyone who would like to see a topic addressed by the participants. Any and all topics, suggestions, gripes, etc. related to MIREX are not only welcomed, they are encouraged.

AGENDA TOPICS, IDEAS, SUGGESTIONS, GRIPES, ETC.

Topic 1: First Task Proposal For MIREXDIYDEMO Prototype: Audio Cover Song?

I would appreciate comments and feedback on the idea that we re-run the Audio Cover Song task with the option (encouragement?) that participants use the the proposed MIREXDIYDEMO framework for submission and evaluation. I believe that Audio Cover Song is a good choice because the the ground-truth is fixed (i.e., either the returned items are cover songs or not) and thus requires no human intervention. Open to other suggestions along the same lines. Does look now (as of 11 April, 2007) that we will only be able to support MATLAB and JAVA submissions but this might be subject to change. Fool around with the preliminary prototype at http://cluster3.lis.uiuc.edu:8080/mirexdiydemo/. By the time we reach Vienna, we hope have a Version II up but this, unfortunately (for security reasons), will probably not be open to the general community.

Topic 2: First Proposal on Audio Music Mood Classification

Main points to discuss:

• Taxonomy
  • Derived from music perception theories : Dimensional like Thayer's or Categorical like Juslin, Hevner
  • Taken from a practical data collection (and maybe clustering to have less categories) : AllMusicGuild, MoodLogic, LastFM
  • Both?
• Ground Truth
  • Human evaluators by using an online application comparable to IMIRSEL's Evalutron 6000
  • Collect labels from popular music websites (LastFM?)
  • Both?
• Data
  • Why not using stereo files? (general question)

Topic 3: Resurrecting drum detection task from 2005

The task could be run quite easily based on the decisions and specifications from 2005. But would there be enough participants? New data from ENST-drums?

Topic 4: New task of structural analysis

To discuss:

• Problem definition: just chorus detection or full description?
  • Chorus detection has been done more and there would be data available from RWC. Chorus detection in a way easier problem to specify and to evaluate.
  • Full description harder. What is correct description? (Levels of hierarchy and locations of borders between parts, etc.)
• Data
  • RWC: AIST annotations of chorus sections, available for all
  • TUT-structure data: commercial audio (also part from RWC Pop), annotations of clear repeated parts + some solos etc. Annotations do not cover whole songs. Amount of data limited, just 50 pieces. Ground truth not available publicly, but for the evaluation.
  • Beatles data: Some annotations are known to be made based on Alan Pollock's "notes on"-series. Availability of the ground truth?
• Participants?
