(1) LORELEI Oromo Incident Language Pack was developed by LDC and is comprised of approximately 3.9 million words of Oromo monolingual text, 25,000 words of English monolingual text, 135,000 words of parallel and comparable Oromo-English text, and 50,000 words of data annotated for Entity Discovery and Linking and Situation Frames. It contains all of the text data, annotations, supplemental resources and related software tools for the Oromo language that were used in the DARPA LORELEI / LoReHLT 2017 Evaluation.
The evaluation protocol was based on a scenario in which 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 Detection and Linking and Situation Frame annotations identified “entities,” “needs” (such as a need for food) and “issues” (such as civil unrest) to be detected by systems for scoring purposes. Situation frame analysis was designed to extract basic information that would be useful for planning a disaster response effort.
The knowledge base for the entity linking annotation in this corpus is available separately as LORELEI Entity Detection and Linking Knowledge Base (LDC2020T10).
LORELEI Oromo Incident Language Pack is distributed via web download.

(1) LORELEI Entity Detection and Linking Knowledge Base was developed by LDC and contains the full LORELEI Entity Detection and Linking (EDL) Knowledge Base (KB) used for all LORELEI Representative Language and Incident Language Pack entity linking annotation. 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 like natural disasters or disease outbreaks.
The KB in this release supported the EDL task in LORELEI for four entity types -- geo-political entities (GPE), locations (LOC), persons (PER) and organizations (ORG) -- and contains a total of 10,216,832 entities. There are four inputs to the KB, each designated by a unique "origin" code in the KB, as follows: GPE and LOC entities from a snapshot of GeoNames, PER entities from the CIA World Leaders List, ORG entities from Appendix B of the CIA World Factbook, and additional entities manually created by LDC for each of the representative and incident languages in the LORELEI Program.

(3) BOLT English Translation Treebank - Chinese Discussion Forum was developed by LDC and consists of 147,432 tokens of web discussion forum data translated from Chinese to English and annotated for part-of-speech and syntactic structure.
The source data is Chinese discussion forum web text collected by LDC in 2011 and 2012, translated into English and released in BOLT Chinese Discussion Forum Parallel Training Data (LDC2017T05). A subset of the translated text -- 148 files representing 147,432 tokens -- was selected for the treebank and annotated for word-level tokenization, part-of-speech and syntactic structure. Only the translated English text is included in the source data for this release.
Part-of-speech and treebank annotation conformed to Penn Treebank II style, incorporating changes to those guidelines that were developed under the GALE (Global Autonomous Language Exploitation) program. Supplementary guidelines for English treebanks and web text are included with this release.

(4) Multi-Language Conversational Telephone Speech 2011 -- Mandarin Chinese was developed by LDC and is comprised of approximately 25 hours of telephone speech in Mandarin Chinese.
The data were collected primarily to support research and technology evaluation in automatic language identification, and portions of these telephone calls were used in the NIST 2011 Language Recognition Evaluation (LRE). Participants were recruited by native speakers who contacted acquaintances in their social network. Those native speakers made one call, up to 15 minutes, to each acquaintance. The data was collected using LDC's telephone collection infrastructure, comprised of three computer telephony systems. Human auditors labeled calls for callee gender, dialect type and noise.
LDC has also released the following as part of the Multi-Language Conversational Telephone Speech 2011 series:
- Slavic Group (LDC2016S11)
- Turkish (LDC2017S09)
- South Asian (LDC2017S14)
- Central Asian (LDC2018S03)
- Central European (LDC2018S08)
- Spanish (LDC2018S12)
- Arabic (LDC2019S02)
- English (LDC2019S06)
- East Asian (LDC2019S15)
