Cross sentence alignment based on singular value decomposition

This paper describes a way of performing alignment of Portuguese-Chinese bilingual pairs from the given two documents. Extracting the alignment pairs is a critical step for building Portuguese-Chinese bilingual corpus for Example Based Machine Translation Systems (EBMT). In short, the proposed alignment system performs four steps: break down the document into sentences level, score each pair or sentence by different features, apply Singular Value Decomposition on the results, extract the aligned pair base on a similarity function.
