Rich Transcription 2007 Evaluation
The Rich Transcription 2007 Meeting Recognition
evaluation was held during the Spring of 2007 in conjunction with the
2007 Classification
of Events,
Activities and Relationships (CLEAR) Evaluation and Evaluation
Workshop.
The RT evaluation series is a collaborative effort of several
projects: The Augmented
Multi-Party Interaction (AMI) program, the Computers
In the Human Interaction Loop (CHIL), the NIST Speech Group, and
the Video Analysis and Content Exploitation (VACE) program. The
RT evaluation was the 5th open evaluation of technologies for the
meeting domain. The presentations and preliminary system
description papers from the RT Workshop held May 10-11, 2007 can be
found on the Agenda from the
meeting.
We are currently beginning to plan the next RT
evaluation. If you'd like to join the RT community and/or
participate in the
evaluation, send your inquiries to rteval@nist.gov.
Evaluation Planning
The RT-07 Evaluation
Plan-V2 was released 2007.2.15. The changes
compared to V1 include: coffee breaks added as a new sub domain,
the IHM reference segmentation condition was added , and clarifications
to the LDC corpora resources.
We meet via conference calls to discuss topics. The next call is
scheduled for December 5, 2006 at 11:00 EST. The minutes of the
conference calls are in the following table:
- Minutes of
the Tuesday, October 17, 2006 conference call
- Minutes of
the Tuesday, November 14, 2006 conference call
- Minutes of
the Tuesday, December 5, 2006 conference call
- Minutes of
the Thusday, December 21, 2006 conference call
- Minutes of
the Friday, January 19, 2007 conference call
Contributing Conference Room Meeting Recordings for the
Evaluation Set
Each year members of the RT community contributed meeting recordings to
form the conference room test set. If you are in a position to
donate recordings, here are the requirements:
- The data must be delivered to NIST by December 13, 2006
- The meetings must be from the conference room meeting
sub-domain which means: there must be 2-12 meeting participants and the
meeting should be goal-oriented.
- Each participant must wear a close talking, cardiod or
super-cardiod microphone.
- There must be at least 3 table top microphones located
between the particiapants, one of which should be designated as the
most-central microphone.
- There must be at least one digital video stream. NIST
will distributed mpeg-2, NTSC, 30 frames-per-second, XX I-frames per
second. If you are not collecting this kind of video, the video
must be of sufficient quality to trans-code it to the distribution
format.
- The microphone recordings and video recordings must be
synchronized. If the data collection infrastructure can not
provide the synchronization, the meeting recordings must include
directors "claps" before the meeting begins and after it ends using a
modified directors clapboard that includes a simultaneous flash.
The paper "Synchronizing Multimodal
Data Streams Acquired Using Commodity Hardware" (Michel, Stanford)
contains a description of how the director's clapboard is used by NIST
to synchronize its audio and video streams. A modified clapboard
is easy to make from the pictures
of NIST's clapboard.
Evaluation Agreements and Data Licenses
Participants of the RT-07 evaluation must complete and return to NIST
the RT-07 Evaluation Participation Agreement and the CHIL Data use
license. Participants must also complete the
AMI license which is
available online at the URL corpus.amiproject.org.
There are evaluation agreement and CHIL license documents that must be
downloaded:
No training data
or evaluation data will be distributed until NIST receives the above
forms.
Data Resources
Participants of the evaluation are given access to RT data
resources.
The password protected page contains textual resources for previous
year's evaluation corpora and links/pointers to other resources.
Participants may be eligble to recieve selected LDC corpora for
free. Contact NIST for details.
Software
- SCTK
v2.2.4 20070501-1541
The latest version of SCTK. This package includes support for the
SASTT task and now includes the rttmSmooth.pl, rttmSort.pl, and
md-eval.pl scripts.
- SASTT-kit-v2 The
starter kit for SASTT scoring.
- spkr2sad-v1.pl
Convert an RTTM
reference file for the Speaker Diarization task (or system output) to a
Speech Activity Detection RTTM file. The output must be smoothed with
rttmSmooth.pl to remove the overlapping segments.
RT-07 System Description Papers and Workshop Presentations
RT Participants are expected to prepare a publication-quality
system description
paper for each task they participated in and presenters are expected to
provided PDFs of their slides for the workshop. The papers and
presentations will be made
available online during the RT-workshop and then later on the RT
website. The submission deadline for papers is May 3, 2007 and
the deadline for submitting PDFs of your presentations (two slides per
page) is May 7, 2007.
A workshop proceedings will be published by Springer under the
LNCS
bookseries jointly with CLEAR. Therefore we ask you to submit revised
final versions of
your papers after the workshop. The tentative deadline will be June
1, 2007. A copy of the proceedings will be send to each workshop
participant.
Please use the Springer LNCS style to format your paper. A
style file for Latex2e can be found here.
Further style files for Latex, Word and Framemaker can be found on Springer's
website.
Paper Length: You may submit a paper of up to 12 pages
for every evaluation task in which you participated.
Please send your papers and presentations to Jerome Ajot (ajot
at nist dot
gov).
