How Much Does Tokenization Affect Neural Machine Translation?

20 Dec 2018Miguel DomingoMercedes Garcıa-MartınezAlexandre HelleFrancisco CasacubertaManuel Herranz

Tokenization or segmentation is a wide concept that covers simple processes such as separating punctuation from words, or more sophisticated processes such as applying morphological knowledge. Neural Machine Translation (NMT) requires a limited-size vocabulary for computational cost and enough examples to estimate word embeddings... (read more)
