Spring 2024 data scholarship application deadline

Applications are now being accepted through January 15, 2024 for the Spring 2024 LDC data scholarship program which provides university students with no-cost access to LDC data. Consult the LDC Data Scholarships page for more information about program rules and submission requirements.

New publications:
REMIX Telephone Collection was developed by LDC and contains 320 hours of English conversational telephone speech from 358 speakers who had completed all tasks in one of the previous LDC Mixer collections, specifically, Mixers 4-7. The data was collected in 2012; recordings in this corpus were used to support the NIST 2012 Speaker Recognition Evaluation. Speakers completed up to 12 calls lasting up to 10 minutes conversing on suggested topics. They were asked that half of the calls be made in a "noisy" environment, e.g., from a speakerphone, a busy street, noisy store or office, or a room with loud background noise. Speaker metadata is included. 

2023 members can access this corpus through their LDC accounts. Non-members may license this data for a fee.

News Sub-domain Named Entity Recognition was developed at the University of Pennsylvania and contains over 20,000 English news sentences annotated with named entities and categorized into sub-domains. The sentences were extracted from The New York Times Annotated Corpus (LDC2008T19). Named entity annotation was based on the CoNLL-2003 guidelines and annotation scheme. Sentences were labeled with person (PER), location (LOC) and organization (ORG) tags using phrase matching with a manual second pass. Sub-domains are: Arts (+Weekend/Cultural), Business (+Financial), Classifieds (+Obituary), Editorial, Foreign, Metropolitan, Sports and Others. "Others" includes topics such as Real Estate, New Jersey Weekly, Book Review, Job Market, Science, and Health & Fitness.

2023 members can access this corpus through their LDC accounts provided they have submitted a signed copy of the special license agreement. Non-members may license this data for a fee.
