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
