*Spring 2012 LDC Data Scholarship Program*
Applications are now being accepted through January 15, 2012 for the
Spring 2012 LDC Data Scholarship program! The LDC Data Scholarship
program provides university students with access to LDC data at no-cost.
This program is open to students pursuing both undergraduate and
graduate studies in an accredited college or university. LDC Data
Scholarships are not restricted to any particular field of study;
however, students must demonstrate a well-developed research agenda and
a bona fide inability to pay. The selection process is highly competitive.
The application consists of two parts:
(1) *Data Use Proposal*. Applicants must submit a proposal describing
their intended use of the data. The proposal must contain the
applicant's name, university, and field of study. The proposal should
state which data the student plans to use and contain a description of
their research project.
Applicants should consult the LDC Corpus Catalog
<http://www.ldc.upenn.edu/Catalog/index.jsp> for a complete list of data
distributed by LDC. Due to certain restrictions, a handful of LDC
corpora are restricted to members of the Consortium. Applicants are
advised to select a maximum of one to two data sets; students may apply
for additional data sets during the following cycle once they have
completed processing of the initial data sets and publish or present
work in some juried venue.
(2) *Letter of Support*. Applicants must submit one letter of support
from their thesis adviser or department chair. The letter must confirm
that the department or university lacks the funding to pay the full
Non-member Fee for the data and verify the student's need for data.
For further information on application materials and program rules,
please visit the LDC Data Scholarship
<http://www.ldc.upenn.edu/About/scholarships.html> page.
Students can email their applications to the LDC Data Scholarship
program <mailto:datascholarships at ldc.upenn.edu>. Decisions will be sent
by email from the same address.
The deadline for the Spring 2012 program cycle is January 15, 2012.
*Invitation to join for Membership Year (MY) 2012*
Membership Year (MY) 2012, our 20th Anniversary Year, is open for
joining! We would like to invite all current and previous members of
LDC to renew their membership as well as welcome new organizations to
join the consortium. For MY2012, LDC is pleased to maintain membership
fees at last year's rates -- membership fees will not increase.
Additionally, LDC will extend discounts on membership fees to members
who keep their membership current and who join early in the year.
The details of our early renewal discounts for MY2012 are as follows:
·Organizations who joined for MY2011 will receive a 5% discount when
renewing. This discount will apply throughout 2012, regardless of time
of renewal. MY2011 members renewing before March 1, 2012 will receive an
additional 5% discount, for a total 10% discount off the membership fee.
·New members as well as organizations who did not join for MY2011, but
who held membership in any of the previous MYs (1993-2010), will also be
eligible for a 5% discount provided that they join/renew before March 1,
2012.
The following table provides exact pricing information.

titles of data sets we intend to provide:
·ARRAU 1.2 (Anaphor Resolution and Underspecification)
·TORGO Dysarthic Speech
·Arabic Treebank BN (broadcast news)
·GALE data -- all phases and tasks
·Digital Archive of Southern Speech
·Chinese Dependency Treebank
In addition to receiving new publications, current year members of the
LDC also enjoy the benefit of licensing older data at reduced costs;
current year for-profit members may use most data for commercial
applications.
*New Publications*
(1) 2006 NIST Speaker Recognition Evaluation Training Set
<http://www.ldc.upenn.edu/Catalog/CatalogEntry.jsp?catalogId=LDC2011S09>
was developed by LDC and NIST (National Institute of Standards and
Technology). It contains 595 hours of conversational telephone speech in
English, Arabic, Bengali, Chinese, Hindi, Korean, Russian, Thai and Urdu
and associated English transcripts used as training data in the
NIST-sponsored2006 Speaker Recognition Evaluation (SRE)
<http://www.itl.nist.gov/iad/mig/tests/spk/2006/index.html>. The ongoing
series of SRE yearly evaluations conducted by NIST are intended to be of
interest to researchers working on the general problem of text
independent speaker recognition.
The task of the 2006 SRE evaluation was speaker detection, that is, to
determine whether a specified speaker is speaking during a given segment
of conversational telephone speech. The task was divided into 15
distinct and separate tests involving one of five training conditions
and one of four test conditions. Further information about the test
conditions and additional documentation is available at the NIST web
site for the 2006 SRE
<http://www.itl.nist.gov/iad/mig/tests/spk/2006/index.html> and within
the 2006 SRE Evaluation Plan
<https://secure.ldc.upenn.edu/intranet/docs/LDC2011S09/sre-06_evalplan-v9.pdf>.
The speech data in this release was collected by LDC as part of the
Mixer <http://projects.ldc.upenn.edu/Mixer/> project, in particular
Mixer Phases 1, 2 and 3. The Mixer project supports the development of
robust speaker recognition technology by providing carefully collected
and audited speech from a large pool of speakers recorded simultaneously
across numerous microphones and in different communicative situations
and/or in multiple languages. The data is mostly English speech, but
includes some speech in the above languages
The telephone speech segments are multi-channel data collected
simultaneously from a number of auxiliary microphones. The files are
organized into three types: two-channel excerpts of approximately 10
seconds, two-channel conversations of approximately 5 minutes and
summed-channel conversations also of approximately 5 minutes.
English language transcripts in .ctm format were produced using an
automatic speech recognition (ASR) system.

(2) 2006 NIST/USF Evaluation Resources for the VACE Program - Meeting
Data Test Set Part 2
<http://www.ldc.upenn.edu/Catalog/CatalogEntry.jsp?catalogId=LDC2011V06>
was developed by researchers at the Department of Computer Science and
Engineering <http://www.cse.usf.edu/>, University of South Florida
(USF), Tampa, Florida and the Multimodal Information Group
<http://nist.gov/itl/iad/mig/> at the National Institute of Standards
and Technology (NIST). It contains approximately twenty hours of meeting
room video data collected in 2005 and 2006 and annotated for the VACE
(Video Analysis and Content Extraction) 2006 face and person tracking tasks.
The VACE program was established to develop novel algorithms for
automatic video content extraction, multi-modal fusion, and event
understanding. During VACE Phases I and II, the program made significant
progress in the automated detection and tracking of moving objects
including faces, hands, people, vehicles and text in four primary video
domains: broadcast news, meetings, street surveillance, and unmanned
aerial vehicle motion imagery. Initial results were also obtained on
automatic analysis of human activities and understanding of video
sequences.
Three performance evaluations were conducted under the auspices of the
VACE program between 2004 and 2007. In 2006, the VACE program and the
European Union's Computers in the Human Interaction Loop (CHIL)
<http://gps-tsc.upc.es/imatge/_JosepRamon/CHIL/CHIL.html> collaborated
to hold the Classification of Events, Activities and Relationships
(CLEAR) Evaluation <http://clear-evaluation.org/clear06/>. This was an
international effort to evaluate systems designed to analyze people,
their identities, activities, interactions and relationships in
human-human interaction scenarios, as well as related scenarios. The
VACE program contributed the evaluation infrastructure (e.g., data,
scoring, tools) for a specific set of tasks, and the CHIL consortium,
coordinated by the Karlsruhe Institute of Technology
<http://www.kit.edu/english/index.php>, contributed a separate set of
evaluation infrastructure. To the extent possible, the VACE and CHIL
programs harmonized their evaluation protocols and metrics.
The meeting room data used for the 2006 test set was collected by the
following sites in 2005 and 2006: Carnegie Mellon University (USA),
University of Edinburgh (Scotland), IDIAP Research Institute
(Switzerland), NIST (USA), Netherlands Organization for Applied
Scientific Research (Netherlands) and Virginia Polytechnic Institute and
State University (USA).
