New publications:

(1) BOLT Information Retrieval Comprehensive Training and Evaluation was developed by LDC and consists of all data produced in support of the Information Retrieval (IR) task within the DARPA Broad Operational Language Translation (BOLT) Program, including annotations, source documents and scoring software.

The BOLT IR task sought to support development of systems that could take as input a natural language English query sentence, return relevant responses to that query from a large corpus of informal documents in the three BOLT languages (Arabic, Chinese, and English) and translate responses from non-English documents into English. This release contains (1) natural-language IR queries, system responses to queries, and manually-generated assessment judgments for system responses; (2) discussion forum source documents in Arabic, Chinese and English; (3) scoring software for each evaluation phase; and (4) experimental data developed in Phase 2.

BOLT Information Retrieval Comprehensive Training and Evaluation is distributed via web download.

(2) HAVIC MED Event E051-E060 -- Videos, Metadata and Annotation was developed by LDC and is comprised of approximately 53 hours of user-generated videos with annotation and metadata. To advance multimodal event detection and related technologies, LDC developed, in collaboration with NIST (the National Institute of Standards and Technology), a large, heterogeneous, annotated multimodal corpus for HAVIC (the Heterogeneous Audio Visual Internet Collection) that was used in the NIST-sponsored MED (Multimedia Event Detection) task for several years. HAVIC MED Event E051-E060 is a subset of that corpus, specifically, a collection of event videos for the HAVIC Project originally released to support the 2016 Multimedia Event Detection task.

The data consists of videos of various events (event videos) and videos completely unrelated to events (background videos) harvested by a large team of human annotators. Each event video was manually annotated with a set of judgments describing its event properties and other salient features. Background videos were labeled with topic and genre categories.

HAVIC MED Event E051-E060 -- Videos, Metadata and Annotation is distributed via web download.

(3) Multi-Language Conversational Telephone Speech 2011 -- Spanish was developed by LDC and is comprised of approximately 23 hours of telephone speech in Spanish.

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. Human auditors labeled the 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)

(4) IARPA Babel Kazakh Language Pack IARPA-babel302b-v1.0a was developed by Appen for the IARPA (Intelligence Advanced Research Projects Activity) Babel program. It contains approximately 203 hours of Kazakh conversational and scripted telephone speech collected in 2013 and 2014 along with corresponding transcripts.

The Kazakh speech in this release represents that spoken in the Northeastern and Southern dialect regions of Kazakhstan. The gender distribution among speakers is approximately equal; speakers' ages range from 16 years to 64 years. Calls were made using different telephones (e.g., mobile, landline) from a variety of environments including the street, a home or office, a public place, and inside a vehicle.

IARPA Babel Kazakh Language Pack IARPA-babel302b-v1.0a is available via web download.
