HAVIC Pilot Transcription

<h3>Introduction</h3><br>
<p>HAVIC Pilot Transcription was developed by the Linguistic Data Consortium (LDC) and is comprised of approximately 72 hours of user-generated videos with transcripts based on the English speech audio extracted from the videos. This data set was created in collaboration with <a href="http://www.nist.gov/">NIST</a> (the National Institute of Standards and Technology) as part of the <a href="https://www.ldc.upenn.edu/collaborations/past-projects/havic">HAVIC</a> (the Heterogeneous Audio Visual Internet Collection) project, the goal of which was to advance multimodal event detection and related technologies.</p><br>
<p>LDC has developed a large, heterogeneous, annotated multimodal corpus for HAVIC that has been used in the NIST-sponsored <a href="http://nist.gov/itl/iad/mig/med.cfm">MED</a> (Multimedia Event Detection) task for several years. HAVIC Pilot Transcription supported an experiment to produce a verbatim transcript (quick and rich transcription) based on audio extracted from user-generated videos. It contains the pilot transcripts for selected MED 2011 video files as well as the associated videos.</p><br>
<h3>Data</h3><br>
<p>NIST designated the videos to be transcribed. Annotators generated the transcripts using <a href="https://www.ldc.upenn.edu/language-resources/tools/xtrans">XTrans</a>, which supports manual transcription across multiple channels, languages and platforms. HAVIC transcription guidelines are included in the documentation for this release.</p><br>
<p>Each file was transcribed by a single annotator with no corpus-wide second pass. File samples from each annotator were checked for various errors, including missing transcription, improper mark-up, poor segmentation and missing/added words.</p><br>
<p>All transcription files are in .tdf format, a plain-text, flat-table format with 13 tab-delimited fields. All video files are in .mp4 format (h264), with varying bit-rates and levels of audio fidelity and video resolution.</p><br>
