Comparable corpora have been shown to be useful in several multilingual natural language processing (NLP) tasks. Many previous papers have focused on how to improve the extraction of parallel data from this kind of corpus on different levels. In this paper, we are interested in improving the quality of bilingual comparable corpora according to increased document alignment score. We describe our participation in the bilingual document alignment shared task of the First Conference on Machine Translation (WMT16). We propose a technique based on sourceto-target sentence- and word-based scores and the fraction of matched source named entities. We performed our experiments on English-to-French document alignments for this bilingual task.
