“…This approach assumes that the FST model marks morpheme boundaries. A survey of recent work on FST morphological analyzers for morphologically rich languages shows that marking morpheme boundaries as part of an intermediate representation is a common practice (Lovick et al, 2018;Bowers et al, 2017;Chen and Schwartz, 2018;Andriyanets and Tyers, 2018;Snoek et al, 2014;Çöltekin, 2010). Thus, we anticipate that this is not an onerous requirement.…”

“…The proposed approach builds on the established practice of applying finite state transducers for modelling the phonological and morphological systems of natural languages (Beesley and Karttunen, 2003). In recent years, researchers have demonstrated the suitability of finite state models for a variety of morphologically complex, low-resource languages including Cree, Haida, Kunwinjku, Odawa, Tsuut'ina, and Yupik (Snoek et al, 2014;Harrigan et al, 2017;Arppe et al, 2017a;Arppe et al, 2017b;Bowers et al, 2017;Chen and Schwartz, 2018;Lachler et al, 2018;Lane and Bird, 2019).…”

“…The conventional approach for building an FST morph analyzer is to divide the task into two stages: (a) accounting for the lexicon and morphotactics, and (b) defining the morphophonological rules which use the context at morphotactic boundaries to produce valid surface forms (Beesley and Karttunen, 2003). Many researchers have followed this pattern to build FST analyzers for morphologically complex languages (Çöltekin, 2010;Harrigan et al, 2017;Bowers et al, 2017;Andriyanets and Tyers, 2018;Moeller et al, 2018;Cardenas and Zeman, 2018;Lane and Bird, 2019). Others deviate slightly, e.g., Chen and Schwartz implement a mechanism for stage 2 which applies morphophonemic rules at morpheme boundaries working from left to right (Chen and Schwartz, 2018).…”

Text input technologies for low-resource languages support literacy, content authoring, and language learning. However, tasks such as word completion pose a challenge for morphologically complex languages thanks to the combinatorial explosion of possible words. We have developed a method for morphologically-aware text input in Kunwinjku, a polysynthetic language of northern Australia. We modify an existing finite state recognizer to map input morph prefixes to morph completions, respecting the morphosyntax and morphophonology of the language. We demonstrate the portability of the method by applying it to Turkish. We show that the space of proximal morph completions is many orders of magnitude smaller than the space of full word completions for Kunwinjku. We provide a visualization of the morph completion space to enable the text completion parameters to be fine-tuned. Finally, we report on a web services deployment, along with a web interface which helps users enter morphologically complex words and which retrieves corresponding entries from the lexicon.

“…In recent years there has been an increase in computational linguistic analysis of Indigenous languages spoken in what is now called Canada, and in particular Algonquian languages such as East Cree (Arppe et al, 2017a), Plains Cree (Harrigan et al, 2017), and Odawa (Bowers et al, 2017). This paper adds Michif-a mixed language of Cree and French origin-to the list with a description of LI VERB KAA-OOSHITAHK DI MICHIF.…”

This paper presents a finite-state computational model of the verbal morphology of Michif. Michif, the official language of the Métis peoples, is a uniquely mixed language with Algonquian and French origins. It is spoken across the Métis homelands in what is now called Canada and the United States, but it is highly endangered with less than 100 speakers. The verbal morphology is remarkably complex, as the already polysynthetic Algonquian patterns are combined with French elements and unique morpho-phonological interactions. The model presented in this paper, LI VERB KAA-OOSHITAHK DI MICHIF handles this complexity by using a series of composed finite-state transducers to model the concatenative morphology and phonological rule alternations that are unique to Michif. Such a rulebased approach is necessary as there is insufficient language data for an approach that uses machine learning. A language model such as LI VERB KAA-OOSHITAHK DI MICHIF furthers the goals of Indigenous computational linguistics in Canada while also supporting the creation of tools for documentation, education, and revitalization that are desired by the Métis community.

“…It does not appear that this is the case. Parsing the roughly 10,000 words recorded by Bloomfield with a finite state parser(Bowers et al 2017) revealed only three more words formed with the innovative prefixation strategy beyond the three acknowledged by Bloomfield.5Lockwood (2017) indicates that the Potawatomi analog of Nishnaabemwin nd2and ndI-…”

The categorical deletion of unstressed vowels from iterative feet differentiates serial theories of phonology from parallel theories. Of at least equal importance is whether language learners acquire rhythmic syncope. A potentially illustrative case comes from the recent development of Nishnaabemwin (Algonquian), which extended unstressed vowel reduction until it approximated categorical rhythmic syncope. In response, an entire generational cohort reportedly carried out a dramatic restructuring by innovating a novel set of person prefixes and losing the surface alternations. However, the original reports are subject to some dispute. To shed further light on the status of rhythmic syncope in Modern Nishnaabemwin, this paper details three surveys of the first cohort of speakers born during the near-syncope period. The surveys indicate that, despite familiarity with the original system, the entire generational cohort uniformly adopted the innovative system.
