Spring 2016 LDC Data Scholarship recipients

Congratulations to the recipients of LDC's Spring 2017 data scholarship:

Umad Ul Hassan and Muhammad Awais Zulfiqar: National University of Sciences and Technology (Pakistan); BS Computer Science. Hassan and Zulfiqar are awarded copies of CSLU: Kids’ Speech Version 1.1 and The CMU Kids Corpus for their research in speech recognition for children with learning difficulties.

For information about the program, visit the Data Scholarship page.

New publications:

(1) First-Year Law Students' Court Memoranda consists of 197 English law student writing samples of legal briefs annotated for certain characteristics along with accompanying survey responses by student writers.

The briefs were created in a law school writing class at two law schools in the US Midwest during the 2011-12 academic year. Students who agreed to participate in this study uploaded their briefs to an online survey instrument and answered questions regarding their age, gender, level of education, most recent writing course and method of learning English. The study's purpose was to apply natural language processing approaches to determine any differences in the briefs' language attributable to the students' self-reported genders.

The samples were imported into the General Architecture for Text Engineering (GATE) and annotated by two human coders who identified large text segments specific to the legal genre in which the students wrote, such as text headings, citations, block quotes and footnotes.

Writing samples are presented as MS Word documents and annotations and survey responses are presented in XML format. The data has been anonymized to remove names and other identifying information about the student participants.

First-Year Law Students' Court Memoranda is distributed via web download.

(2) IARPA Babel Haitian Creole Language Pack IARPA-babel201b-v0.2b was developed by Appen for the IARPA (Intelligence Advanced Research Projects Activity) Babel program. It contains approximately 203 hours of Haitian Creole conversational and scripted telephone speech collected in 2012 and 2013 along with corresponding transcripts.

The Babel program focuses on underserved languages and seeks to develop speech recognition technology that can be rapidly applied to any human language to support keyword search performance over large amounts of recorded speech.

The Haitian Creole speech in this release represents that spoken in the Northern, Western and Southern dialect regions in Haiti. The gender distribution among speakers is approximately equal; speakers' ages range from 16 years to 75 years. Calls were made using different telephones (e.g., mobile, landline) from a variety of environments including the street, a home or office, a public place, and inside a vehicle.

Transcripts are encoded in UTF-8.
