Please add your comments and discussions for 2012. <br /> <br /> The main purpose of QBT (Query by Tapping) is to evaluate MIR system in retrieving ground-truth MIDI files by tapping the onset of music notes to the microphone. This task provides query files in wave format as well as the corresponding human-label onset time in symbolic format. For this year's QBT task, we have two corpora for evaluation:<br /> <br /> * Roger Jang's [http://mirlab.org/dataSet/public/MIR-QBT.rar MIR-QBT]: This dataset contains both wav files (recorded via microphone) and onset files (human-labeled onset time).<br /> * Show Hsiao's [http://mirlab.org/dataSet/public/QBT_symbolic.rar QBT_symbolic]: This dataset contains only onset files (obtained from the user's tapping on keyboard).<br /> <br /> == Task description ==<br /> <br /> === Subtask 1: QBT with symbolic input ===<br /> * '''Test database''': About 150 ground-truth monophonic MIDI files in MIR-QBT.<br /> * '''Query files''': About 800 text files of onset time to retrieve target MIDIs in MIR_QBT. These onset files can help participant concentrate on similarity matching instead of onset detection. All onset files cannot guarantee to have perfect detection result from original wav query files.<br /> * '''Evaluation''': Return top 10 candidates for each query file. 1 point is scored for a hit in the top 10 and 0 is scored otherwise (Top-10 hit rate).<br /> <br /> === Subtask 2: QBT with wave input ===<br /> * '''Test database''': About 150 ground-truth monophonic MIDI files in MIR-QBT.<br /> * '''Query files''': About 800 wave files of tapping recordings to retrieve MIDIs in MIR-QBT.<br /> * '''Evaluation''': Return top 10 candidates for each query file. 1 point is scored for a hit in the top 10 and 0 is scored otherwise (Top-10 hit rate).<br /> <br /> == Disucussions for 2012 == <br /> <br /> == Command formats ==<br /> <br /> === Indexing the MIDIs collection ===<br /> Command format should look like this: <br /> <br /> indexing %dbMidi.list% %dir_workspace_root%<br /> <br /> where %dbMidi.list% is the input list of database midi files named as uniq_key.mid. For example: <br /> <br /> QBT/database/00001.mid<br /> QBT/database/00002.mid<br /> QBT/database/00003.mid<br /> QBT/database/00004.mid<br /> ...<br /> <br /> Output indexed files are placed into %dir_workspace_root%. (Note that this step is not required unless you want to index or preprocess the midi database.)<br /> <br /> === Test the query files ===<br /> The command format should be like this:<br /> <br /> qbtProgram %dbMidi_list% %query_file_list% %resultFile% %dir_workspace_root%<br /> <br /> You can use %dir_workspace_root% to store any temporary indexing/database structures. (You can omit %dir_workspace_root% if you do not need it at all.) If the input query files are onset files (for subtask 1), then the format of %query_file_list% is like this:<br /> <br /> qbtQuery/query_00001.onset 00001.mid<br /> qbtQuery/query_00002.onset 00001.mid<br /> qbtQuery/query_00003.onset 00002.mid<br /> ...<br /> <br /> (Pleae refer to the readme.txt of the downloaded MIR-QBT corpus for the format of onset files.)<br /> <br /> If the input query files are wave files (for subtask 2), the the format of %query_file_list% is like this:<br /> <br /> qbtQuery/query_00001.wav 00001.mid<br /> qbtQuery/query_00002.wav 00001.mid<br /> qbtQuery/query_00003.wav 00002.mid<br /> ...<br /> <br /> The result file gives top-10 candidates for each query. For instance, for wave query file, the result file should have the following format for subtask 1:<br /> <br /> qbtQuery/query_00001.onset: 00025 01003 02200 ... <br /> qbtQuery/query_00002.onset: 01547 02313 07653 ... <br /> qbtQuery/query_00003.onset: 03142 00320 00973 ... <br /> ...<br /> <br /> And for subtask 2:<br /> <br /> qbtQuery/query_00001.wav: 00025 01003 02200 ... <br /> qbtQuery/query_00002.wav: 01547 02313 07653 ... <br /> qbtQuery/query_00003.wav: 03142 00320 00973 ... <br /> ...<br /> <br /> <br /> <br /> == Submission opening date ==<br /> <br /> Friday August 5th 2012<br /> <br /> == Submission closing date ==<br /> Friday September 2nd 2012<br /> <br /> == Potential Participants ==<br /> name / email</div>
