2007:Query by Singing/Humming

Status

This is only a very basic draft version of a task proposal. Once more people show interest we can fill in the details.

The goal of the Query-by-Singing/Humming (QBSH) task is the evaluation of MIR systems that take as query input queries sung or hummed by real-world users. More information can be found in:

• MIREX2006 QBSH Task Proposal
• MIREX2006 QBSH Task Discussion

Query Data

1. Roger Jang's corpus (MIREX2006 QBSH corpus) which is comprised of 2797 queries along with 48 ground-truth MIDI files. All queries are from the beginning of references.

2. ThinkIT corpus comprised of 355 queries and 106 monophonic ground-truth midi files (with MIDI 0 or 1 format). There are no "singing from beginning" gurantee. This corpus will be published after the task running.

3. Noise MIDI will be the 5000+ Essen collection(can be accessed from http://www.esac-data.org/).

To build a large test set which can reflect real-world queries, it is suggested that every participant makes a contribution to the evaluation corpus.

Task description

Classic QBSH evaluation:

• Input: human singing/humming snippets (.wav). Queries are from Roger Jang's corpus and ThinkIT corpus.
• Database: ground-truth and noise midi files(which are monophonic). Comprised of Roger 48+106 Jang's and ThinkIT's ground-truth along with 5000+ essen noise midifiles.
• Output: top-20 candidate list.
• Evaluation: Mean Reciprocal Rank (MRR) and Top-X hit rate.

To make algorithms able to share intermediate steps, participants are encouraged to submit separate transcriber and matcher modules instead of integrated ones, which is according to Rainer Typke's suggestion. So transcribers and matchers from different submissions could work together with the same pre-defined interface and thus for us it's possible to find the best combination. Besides, note based approaches (symbolic approaches) and pitch contour based approaches (non-symbolic approaches?) are compared.

Interface suggestion commented by xwu

1. Database indexing/building. Calling format should look like

indexing db_list dir_workspace_root

where db_list is the input list of database midi files named as "ID.mid". For example:

./QBSH/Database/00001.mid
./QBSH/Database/00002.mid
./QBSH/Database/00003.mid
./QBSH/Database/00004.mid
...

Output indexed files are placed into dir_workspace_root.
