Query: Learning the Ordering of Coordinate Compounds and Elaborate Expressions
  in Hmong, Lahu, and Chinese   Coordinate compounds (CCs) and elaborate expressions (EEs) are coordinate
constructions common in languages of East and Southeast Asia. Mortensen (2006)
claims that (1) the linear ordering of EEs and CCs in Hmong, Lahu, and Chinese
can be predicted via phonological hierarchies and (2) these phonological
hierarchies lack a clear phonetic rationale. These claims are significant
because morphosyntax has often been seen as in a feed-forward relationship with
phonology, and phonological generalizations have often been assumed to be
phonetically "natural". We investigate whether the ordering of CCs and EEs can
be learned empirically and whether computational models (classifiers and
sequence labeling models) learn unnatural hierarchies similar to those posited
by Mortensen (2006). We find that decision trees and SVMs learn to predict the
order of CCs/EEs on the basis of phonology, with DTs learning hierarchies
strikingly similar to those proposed by Mortensen. However, we also find that a
neural sequence labeling model is able to learn the ordering of elaborate
expressions in Hmong very effectively without using any phonological
information. We argue that EE ordering can be learned through two independent
routes: phonology and lexical distribution, presenting a more nuanced picture
than previous work. [ISO 639-3:hmn, lhu, cmn]
