AIDA Scenario 3 Practice Topic Source Data and Annotation was developed by LDC and is comprised of English, Russian and Spanish web documents (text, video, image) and annotations. Each phase of the AIDA program centered on a specific scenario, or broad topic area, with related subtopics designated as either practice subtopics or evaluation subtopics. The Phase 3 scenario focused on the COVID-19 global pandemic. This corpus contains source documents and annotations for the Scenario 3 practice topics.

The corpus contains 1417 root documents; 279 documents were annotated. Annotations include:

Event, relation and entity annotation (64 documents)

Claim frame annotation: claims (true or not) relating to the COVID-19 pandemic (203 documents)

Practice topic query claim frames: example claim frames intended to be used by systems as queries to extract similar claims from additional documents (30 documents)

The DARPA AIDA (Active Interpretation of Disparate Alternatives) program aimed to develop a multi-hypothesis semantic engine to generate explicit alternative interpretations of events, situations and trends from a variety of unstructured sources. LDC supported AIDA by collecting, creating and annotating multimodal linguistic resources in multiple languages.

2025 members can access this corpus through their LDC accounts. Non-members may license this data for a fee.

MATERIAL Georgian-English Language Pack was developed by Appen for the IARPA MATERIAL program and contains 79 hours of Georgian 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 half of the speech files, and approximately 3% of the speech data was 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.

2025 members can access this corpus through their LDC accounts provided they have submitted a completed copy of the special license agreement. Non-members may license this data for a fee.

Iraqi Arabic - English Lexical Database was developed by LDC. It has six interrelated tables presenting over 67,000 Iraqi Arabic words as orthographic forms in Arabic script and pronunciation forms in IPA format, along with more than 120,000 English tokens.

This release is the result of a collaboration with Georgetown University Press to enhance and update three dialectal Arabic dictionaries -- Iraqi, Moroccan and Syrian -- originally published in the 1960s. The Georgetown Dictionary of Iraqi Arabic was published in 2013. That work was based on, and expanded, two dictionaries, A Dictionary of Iraqi Arabic: English-Arabic (Clarity, Stowasser and Wolfe, eds., 2003) and A Dictionary of Iraqi Arabic: Arabic-English (Woodhead and Beene, eds., 2003).

The several enhancements developed by LDC in the updated and enhanced dictionary and the lexical database included facilitating comparisons across Arabic dialects and Modern Standard Arabic by providing Arabic script spellings and IPA pronunciations to Iraqi words and phrases; promoting ease of use by language learners and researchers by developing reasonable orthographic conventions for applying the Arabic alphabet to the dialect; and facilitating a user's understanding of morphological and lexical relations by adding information on the linguistic structures of Iraqi Arabic.

The documentation accompanying this release includes instructions for combining into one database the tables in this corpus with the tables in Moroccan Arabic - English Lexical Database LDC2023L01.

2025 members can access this corpus through their LDC accounts provided they have submitted a completed copy of the special license agreement. Non-members may license this data for a fee.

LORELEI Hungarian Representative Language Pack is comprised of over 686 million words of Hungarian monolingual text, 165,000 words of which were translated into English, 2.3 million words of found Hungarian-English parallel text, and 87,000 Hungarian words translated from English data. Approximately 72,500 words were annotated for named entities and over 25,000 words were annotated for full entity (including nominals and pronouns), entity linking and situation frames (identifying entities, needs and issues); over 17,000 words have simple semantic annotation; and close to 10,000 words were annotated for noun phrase chunking. 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).
