Minimally Supervised Morphological Analysis by Multimodal Alignment. David Yarowsky and Richard Wicentowski. Introduction. The Algorithm capable of inducing inflectional morphological analyses of regular and highly irregular forms.
Minimally Supervised Morphological Analysis by Multimodal Alignment
Consider this task as three steps:
Clustering inflectional variants of verbs (e.g. sipped, sipping, and sip).
initially set to (0.5,0.6,1.0,0.98)
The goal is to generalize a mapping function via a generative probabilistic model.
P(inflection | root,suffix,POS)=P(stemchange | root,suffix,POS)
P(solidified | solidify, +ed, VBD)
= P(yi | solidify, +ed, VBD)
≈ 1P(yi | ify, +ed)
+ (1-1)( 2P(yi | fy, +ed)
+ (1-2)( 3P(yi | y, +ed)
+ (1-3)( 4P(yi | +ed)
+ (1-4) P(yi)
POS can be deleted
