Logical Transductions for the Typology of Ditransitive Prosody

no code implementations • NAACL (SIGMORPHON) 2022 • Mai Ha Vu, Aniello De Santo, Hossep Dolatian

Given the empirical landscape of possible prosodic parses, this paper examines the computations required to formalize the mapping from syntactic structure to prosodic structure.

Trees probe deeper than strings: an argument from allomorphy

no code implementations • NAACL (SIGMORPHON) 2022 • Hossep Dolatian, Shiori Ikawa, Thomas Graf

The trigger and target can either be linearly adjacent or non-adjacent, and either the trigger precedes the target (inwardly sensitive) or the target precedes the trigger (outwardly sensitive).

The 2022 SIGMORPHON–UniMorph shared task on large scale morphological inflection generation included a wide range of typologically diverse languages: 33 languages from 11 top-level language families: Arabic (Modern Standard), Assamese, Braj, Chukchi, Eastern Armenian, Evenki, Georgian, Gothic, Gujarati, Hebrew, Hungarian, Itelmen, Karelian, Kazakh, Ket, Khalkha Mongolian, Kholosi, Korean, Lamahalot, Low German, Ludic, Magahi, Middle Low German, Old English, Old High German, Old Norse, Polish, Pomak, Slovak, Turkish, Upper Sorbian, Veps, and Xibe.

Recursive prosody is not finite-state

no code implementations • ACL (SIGMORPHON) 2021 • Hossep Dolatian, Aniello De Santo, Thomas Graf

This paper investigates bounds on the generative capacity of prosodic processes, by focusing on the complexity of recursive prosody in coordination contexts in English (Wagner, 2010).
