Since Thai contains a large number
of monosyllabic words and many polysyllabic words are concatenations of monosyllabic words,
morphological analysis in Thai consists mainly in a joint process of word
segmentation and syllabification. Due to lack of consensus
on what generally constitutes a word in Thai, word segmentation
is task-oriented. For example, in semantic or
syntactic analysis, it is preferable to work with a longer
compound word, whereas in phonological analysis, a syllable-like
word is more suitable. In this subsection, Thai morphological
analyses including both word segmentation and
syllabification are reviewed.
