DEFT Chinese and English Light and Rich ERE Parallel Annotation
MATERIAL Tagalog-English Language Pack
LORELEI Somali Representative Language Pack

New publications:
DEFT Chinese and English Light and Rich ERE Parallel Annotation was
developed by LDC and consists of 179 Chinese discussion forum
documents and their English translations 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. 179 Chinese-English
document pairs were annotated following Light ERE annotation
guidelines; a subset of 171 Chinese-English document pairs were also
labeled with Rich ERE annotation. The source data and English
translations were drawn from BOLT Chinese Discussion Forum Parallel
Training Data (LDC2017T05), originally collected and translated by LDC
under the DARPA BOLT program.
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 Tagalog-English Language Pack was developed by Appen for the
IARPA MATERIAL program and contains 100 hours of Tagalog
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 30% of the speech files, 2% of which were
translated into English. This release also includes domain
annotations, 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.
2026 members can access this corpus through their LDC accounts

agreement. Non-members may license this data for a fee.

LORELEI Somali Representative Language Pack contains over 13 million
words of Somali monolingual text, 800,00 words of which were
translated into English, and 106,000 Somali words translated from
English data. Approximately 73,000 words were annotated for simple
named entities, around 23,000 words were annotated for full entity
(including nominals and pronouns), and over 10,000 words were covered
by noun phrase chunking annotation. Data was collected from discussion
forum, news, reference, social network, and weblogs.
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. Representative
languages were selected to provide broad typological coverage.
The knowledge base for entity linking annotation is available
separately as LORELEI Entity Detection and Linking Knowledge Base
(LDC2020T10).
