In this newsletter: - Cataloging the communication of Asian Elephants - New publications: - 2006 NIST/USF Evaluation Resources for the VACE Program - Meeting Data Test Set Part 1 - Cataloging the communication of Asian Elephants LDC distributes a broad selection of databases, the majority of which are used for human language research and technology development. Our corpus catalog also includes the vocalizations of other animal species. We'd like to highlight the intriguing work behind one such animal communication corpus, Asian Elephant Vocalizations LDC2010S05. New Publications (1) 2006 NIST/USF Evaluation Resources for the VACE Program - Meeting Data Test Set Part 1 was developed by researchers at the Department of Computer Science and Engineering, University of South Florida (USF), Tampa, Florida and the Multimodal Information Group at the National Institute of Standards and Technology (NIST). It contains approximately fifteen 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) collaborated to hold the CLassification of Events, Activities and Relationships (CLEAR) Evaluation. 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, contributed a separate set of evaluation infrastructure. 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). Each site had its own independent camera setup, illuminations, viewpoints, people and topics. Most of the datasets included High-Definition (HD) recordings, but those were subsequently formatted to MPEG-2 for the evaluation. *
The 2008 evaluation was distinguished from prior evaluations, in particular those in 2005 and 2006, by including not only conversational telephone speech data but also conversational speech data of comparable duration recorded over a microphone channel involving an interview scenario. The speech data in this release was collected in 2007 by LDC at its Human Subjects Data Collection Laboratories in Philadelphia and by the International Computer Science Institute (ICSI) at the University of California, Berkeley. This collection was part of the Mixer 5 project, which was designed to support 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. Mixer participants were native English speakers and bilingual English speakers. The telephone speech in this corpus is predominately English; all interview segments are in English. Telephone speech represents approximately 523 hours of the data, and microphone speech represents the other 427 hours. The telephone speech segments include summed-channel excerpts in the range of 5 minutes from longer original conversations. The interview material includes single channel conversation interview segments of at least 8 minutes from a longer interview session. English language transcripts were produced using an automatic speech recognition (ASR) system. 2008 NIST Speaker Recognition Evaluation Training Set Part 2 is distributed on 7 DVD-ROM. 2011 Subscription Members will automatically receive two copies of this corpus. 2011 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for $2000. * (3) French Gigaword Third Edition is a comprehensive archive of newswire text data that has been acquired over several years by LDC. This third edition updates French Gigaword Second Edition (LDC2009T28) and adds material collected from January 1, 2009 through December 31, 2010. The two distinct international sources of French newswire in this edition, and the time spans of collection covered for each, are as follows: Agence France-Presse (afp_fre) May 1994 - Dec. 2010 Associated Press French Service (apw_fre) Nov. 1994 - Dec. 2010 All text data are presented in SGML form, using a very simple, minimal markup structure; all text consists of printable ASCII, white space, and printable code points in the 'Latin1 Supplement' character table, as defined by the Unicode Standard (ISO 10646) for the 'accented' characters used in French. The Supplement/accented characters are presented in UTF-8 encoding. The overall totals for each source are summarized below. Note that the 'Totl-MB' numbers show the amount of data when the files are uncompressed (i.e. approximately 15 gigabytes, total); the 'Gzip-MB' column shows totals for compressed file sizes as stored on the DVD-ROM; the 'K-wrds' numbers are simply the number of white space-separated tokens (of all types) after all SGML tags are eliminated.
French Gigaword Third Edition is distributed on 1 DVD-ROM. 2011 Subscription Members will automatically receive two copies of this corpus. 2011 Standard Members may request a copy as part of their 16 free membership corpora. Non-members may license this data for US$4500. |
