| Challenge: | a large corpus covering 22 Turkic languages is included in this paper . low-resource MT evaluation has traditionally focused on European languages due to limitations of available technology and resources. |
| Approach: | They present a case study of the practical application of MT in the Turkic language family . they propose to realize the gains of NMT for Turkic languages under high-resource to extremely low-resourced scenarios. |
| Outcome: | The proposed study shows that the new methods can be used in the Turkic language family . the results highlight bottlenecks in building competitive systems . |
A Free/Open-Source Morphological Analyser and Generator for Sakha (2022.lrec-1)
Copied to clipboard
| Challenge: | a morphological transducer for Sakha is being developed for use in downstream tasks . the marginalised language is subject to increasing economic and cultural peril due to climate change . |
| Approach: | They describe the development of a morphological analyser and generator for Sakha . the transducer has coverage of solidly above 90%, and high precision . it is already being used in downstream tasks such as linguistic maintenance . |
| Outcome: | The proposed morphological analyser has coverage of 90% and high precision . it is already being used in computer assisted language learning applications . |
Toward a Paradigm Shift in Collection of Learner Corpora (2020.lrec-1)
Copied to clipboard
| Challenge: | a pilot version of the Revita Learner Corpus (ReLCo) is available for Russian learners . it is collected and annotated automatically while learners practice with Revita . |
| Approach: | They present the first version of the longitudinal Revita Learner Corpus (ReLCo) for Russian . the corpus contains 8 422 sentences exhibiting several types of errors committed by learners . |
| Outcome: | The Russian version of the Revita Learner Corpus is publicly available . the pilot study shows that the corpus grows continuously while learners practice . |

| Challenge: | The Universal Morphology project provides broad-coverage instantiated morphological inflection tables for hundreds of diverse languages. |
| Approach: | They propose a language-independent feature schema for rich morphological annotation and a type-level resource of annotated data in diverse languages realizing that schema. |
| Outcome: | The proposed schema has added 66 new languages, including 24 endangered languages. |
