Abstract

In this paper, we propose a two-level Needleman-Wunsch algorithm to align two subtitle files. We consider each subtitle file as a sequence of sentences, and each sentence as a sequence of characters. Our algorithm aligns the OCR and Web subtitles from both sentence level and character level. Experiments on ten datasets from two TV shows indicate that our algorithm outperforms the state-of-the-art approaches with an average precision and recall of 0.96 and 0.95.
