New publications: AnnoDIFP (Annotated Data for the Investigation of Facets of Personality) CTS (Conversational Telephone Speech) Audio and Transcriptshttps://catalog.ldc.upenn.edu/LDC2025S10 was developed by LDC, the Florida Institute of Technology https://www.fit.edu/ and the University of New Havenhttps://www.newhaven.edu/index.php to support algorithm development for predicting personality traits. It contains 242.52 hours of English telephone audio recordings and transcripts from 1,179 telephone calls involving 327 participants paired with scores from two self-reported personality assessments, HEXACO Personality Inventory (Revised) (HEXACO-PI-R) and Short Dark Triad (SD3).
This corpus contains audio and transcripts for 277 participants and transcripts only for 50 participants. Telephone calls were collected using LDC's robot-operator platformhttps://www.ldc.upenn.edu/about/facilities/human-subjects-collection. The operator called participants every 24 hours during their indicated availability and paired them with another participant to speak on a prompted topic for 10 minutes. Transcripts were produced automatically using the Rev.aihttps://www.rev.ai/ speech-to-text service.
2025 members can access this corpus through their LDC accounts. Non-members may license this data for a fee.

LORELEI Ilocano Incident Language Packhttps://catalog.ldc.upenn.edu/LDC2025T16 was developed by LDC and is comprised of 8.9 million words of Ilocano monolingual text, 3.3 million words of English monolingual text, 3.2 million words of parallel Ilocano-English text, and 3 million words annotated for entity discovery and linking and situation frames. It constitutes all of the text data, annotations, supplemental resources, and related software tools for the Ilocano language used in the DARPA LORELEI / LoReHLT 2019 Evaluationhttps://www.nist.gov/itl/iad/mig/lorehlt-evaluations.
The LORELEI (Low Resource Languages for Emergent Incidents) program was concerned with building human language technology for low resource languages in the context of emergent situations. In the evaluation scenario, an unforeseen event triggered a need for humanitarian and logistical support in a region where the incident language had received little or no attention in NLP research. Evaluation participants provided NLP solutions, including information extraction and machine translation, with limited resources and limited development time.
Data was collected from news, social network, weblog, newsgroup, discussion forum, and reference material. Entity discovery and linking annotation identified entities to be detected by systems for scoring purposes. Situation frame analysis was designed to extract basic information about needs and relevant issues for planning a disaster response effort.
2025 members can access this corpus through their LDC accounts. Non-members may license this data for a fee.
