Target language code

Line breaks and paragraph breaks always end a sentence. Works for any language pair, including Urdu, Arabic, Chinese and Japanese punctuation.

Aligned sentences.

Highlighted rows are the least certain matches (non 1-to-1, or the highest 15% of costs). Lower cost means a better length fit.

Method & interpretation.

Alignment uses the length-based method of Gale & Church (1993): sentence lengths in letters and digits are compared against the overall length ratio of the two texts, allowing 1–1, 1–2, 2–1, 2–2 and unmatched sentences. No dictionary is used, so check rows where whole sentences were added or dropped.
