New publications: DEFT Spanish Light and Rich ERE Annotationhttps://catalog.ldc.upenn.edu/LDC2025T04 was developed by LDC and consists of 158 Spanish discussion forum and newswire documents annotated for entities, relations, and events (ERE). Light ERE annotation labels entity mentions for the target set of entity, relation, and event types between and among those entities including coreference. Rich ERE annotation expands types and tagging in the entities, relations, and events annotation tasks and replaces strict event coreference with a more loosely defined event hopper annotation. The source data consists of Spanish newswire text and Latin American discussion forum data from DEFT Spanish Treebank LDC2018T01https://catalog.ldc.upenn.edu/LDC2018T01. 128 documents were annotated following Light ERE annotation guidelines. 154 files were labeled with Rich ERE annotation, 124 of which were also labeled with Light ERE annotation.
DARPA's Deep Exploration and Filtering of Text (DEFT) program aimed to address remaining capability gaps in state-of-the-art natural language processing technologies related to inference, causal relationships and anomaly detection. LDC supported the DEFT program by collecting, creating and annotating a variety of data sources.

MATERIAL Kazakh-English Language Packhttps://catalog.ldc.upenn.edu/LDC2025S03 was developed by Appenhttp://www.appen.com/ for the IARPA MATERIALhttps://www.iarpa.gov/index.php/research-programs/material program and contains 57 hours of Kazakh conversational telephone speech, transcripts, English translations, annotations, and queries. Calls were made using different telephones (e.g., mobile, landline) from a variety of environments. Transcripts cover approximately 17% of the speech files, all of which were translated into English. This release also includes English queries and their relevance annotations. The MATERIAL program focused on underserved languages with the ultimate goal to build cross language information retrieval systems to find speech and text content using English search queries.
