| Challenge: | a finite state transducer (FST) for the transitive verb system of Tsuut'ina (ISO 639-3: srs) is described for the Dene (Athabaskan) language spoken in Alberta, Canada. |
| Approach: | They describe the expansion of a finite state transducer (FST) for the transitive verb system of Tsuut'ina (ISO 639-3: srs) Dene languages have unique templatic morphology, in which lexical, inflectional and derivational tiers are interlaced. |
| Outcome: | The proposed model can handle a great range of common and rare argument structure types, including ditransitive and uniquely Dene object experiencer verbs. |

Copied to clipboard
| Challenge: | a transitive verb takes up to 1,740 unique features and is highly complex, with a morphological complexity of 80.3% . a finite-state approach has been used to build morphology and phonology resources for Nen, an underresourced language in Papua New Guinea. |
| Approach: | They propose to use Finite-State methods to build a verbal morphological parser for an under-resourced Papuan language, Nen. |
| Outcome: | The proposed model is half the size of the full decomposed model, while the 'Chunking' model is under half the scale of the decomposer, with an overall accuracy of 80.3%. |

A Computational Architecture for the Morphology of Upper Tanana (L18-1)
Copied to clipboard
| Challenge: | a computational model of Upper Tanana is described to model the Dene language . the model uses lexical-inflectional verb classes to predict possible derivations and their morphological behavior. |
| Approach: | They propose a computational model of Upper Tanana, a highly endangered Dene language . the model parses and generates inflected Upper Tanans and uses a lexical-inflectional verb system to predict possible derivations and their morphological behavior. |
| Outcome: | The proposed model parses and generates inflected Upper Tanana verb forms . it also uses the language's verb theme category system to predict possible derivations and their morphological behavior . |
Bootstrapping Techniques for Polysynthetic Morphological Analysis (2020.acl-main)
Copied to clipboard
| Challenge: | Polysynthetic languages have exceptionally large and sparse vocabularies due to the number of morpheme slots and combinations in a word. |
| Approach: | They propose linguistically-informed approaches for bootstrapping a neural morphological analyzer . they use a finite state transducer to train an encoder-decoder model . |
| Outcome: | The proposed method improves on a polysynthetic language's model by "hallucinating" missing linguistic structure and resampling from a Zipf distribution to simulate a more natural distribution of morphemes. |
