... non-transliterations by N. 3.2 Implementation Details We use the Forward-Backward algorithm to estimate the counts of multigrams. The algorithm has a for- ward variable α and a backward variable ... system learns this as a non-transliteration but it is wrongly annotated as a transliteration in the gold standard. Arabic nouns have an article “al” attached to them which is translated...
