To appear.https://hdl.handle.net/10092/103880We present an extension of the Morfessor Base line model of unsupervised morphological seg mentation (Creutz and Lagus, 2007) that in corporates abstract templates for reduplication, a typologically common but computationally underaddressed process. Through a detailed in vestigation that applies the model to Maori, the ¯ Indigenous language of Aotearoa New Zealand, we show that incorporating templates improves Morfessor’s ability to identify instances of redu plication, and does so most when there are multiple minimally-overlapping templates. We present an error analysis that reveals important factors to consider when applying the extended model and suggests useful future directions.enAll rights reserved unless otherwise statedConference Contributions - Published2022-06-02Fields of Research::47 - Language, communication and culture::4704 - Linguistics::470409 - Linguistic structures (incl. phonology, morphology and syntax)Fields of Research::45 - Indigenous studies::4507 - Te ahurea, reo me te hītori o te Māori (Māori culture, language and history)Nga Upoko Tukutuku / Maori Subject Headings::Reo Māori | Reo rangatira; Te reo Māori; Te reo rangatira; Māori language
