New publications:
MATERIAL Farsi-English Language Pack was developed by Appen for the IARPA MATERIAL program and contains 61 hours of Farsi 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, and approximately 3% of the speech files 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.

Abstract Meaning Representation 3.0 - Machine Translations was developed by the Center for Computational Linguistics at KU Leuven in the HORIZON2020 project SignON. It is an automatic translation of a subset of sentences from Abstract Meaning Representation (AMR) Annotation Release 3.0 (LDC2020T02) into Spanish, Irish Gaelic, and Dutch.
AMR 3.0 training, development, and test splits were translated using Google Translate. "Unsplit" directories were not translated and are not included in this release. Translations were not manually verified, but formal issues (such as unexpected new lines) were corrected, and special tokens and encoding issues were fixed with the Python tool ftfy.fix_text.
AMR 3.0 is a semantic treebank of over 59,000 English natural language sentences drawn from material collected by LDC, specifically, discussion forum text from the DARPA BOLT and DARPA DEFT programs, transcripts and English translations of Mandarin Chinese broadcast news programming, Wall Street Journal text, translated Xinhua news texts, various newswire texts from NIST OpenMT evaluations, and weblog data from the DARPA GALE program.
