Multi-rate HMMs for Word Alignment

posted on 2018-08-08, 00:00 authored by Elif Eyigoz, Daniel Gildea, Kemal OflazerKemal OflazerWe apply multi-rate HMMs, a tree structured HMM model, to the word-alignment problem. Multi-rate HMMs allow us to model reordering at both the morpheme level and the word level in a hierarchical fashion. This approach leads to better machine translation results than a morpheme aware model that does not explicitly model morpheme reordering.
