Four corpora withdrawn from the LDC Catalog 

We regret to announce that The New York Times Annotated Corpus LDC2008T19 has been withdrawn from the LDC Catalog by the data provider. Because they contain data from LDC2008T19, the following three corpora are also withdrawn from the Catalog: Benchmarks for Open Relation Extraction LDC2014T27, Concretely Annotated New York Times LDC2018T12, and News Sub-domain Named Entity Recognition LDC2023T12. Organizations and individuals who have previously licensed any of these data sets can continue to use them under the terms of their respective special license agreements.

New publications:
 
Second Language University Speech Intelligibility Corpus was developed by Northern Arizona University, The Pennsylvania State University, and The University of Texas at Dallas. It contains 10.5 hours of English speech collected from 66 international faculty and university students representing 15 language backgrounds at 10 North American universities. This release also includes orthographic transcriptions for all recordings, intelligibility scores for 73% of the files, speaker metadata, and aligned Praat textgrids. 
 
The speech data is comprised of presentations, descriptions, reflections, and microteaching tasks. Speakers were recruited from courses at intensive English programs and oral skills courses for international graduate students seeking to become international teaching assistants. 
 
2024 members can access this corpus through their LDC accounts provided they have submitted a completed copy of the special license agreement. Non-members may license this data for a fee.

AIDA Scenario 1 Practice Topic Annotation was developed by LDC and is comprised of annotations for 212 English, Russian and Ukrainian web documents (text, image and video) from AIDA Scenario 1 Practice Topic Source Data (LDC2023T11), specifically, the set of practice documents designated for annotation in Phase 1.

Annotations are presented as tab separated files in the following categories for each topic:

  • Mentions: single references in source data to a real-world entity or filler, event, or relation. 
  • Slots: pre-defined roles in an event or relation filled by an argument (entity mention). 
  • Linking: entity mentions linked to entries in the knowledge base as a method of indicating the real-world entity to which an entity referred.
2024 members can access this corpus through their LDC accounts. Non-members may license this data for a fee.
