【Abstract】Automatic alignment of parallel corpora is an important research subject in natural language processing area. An efficient small-dictionary-oriented algorithm for alignment of English-Chinese parallel corpora is proposed in this paper in order to improve the efficiency of translation-based approach to parallel corpora alignment, and enhance its precision when the dictionary used is small. The algorithm has competitive precision under the condition of small dictionary, and doubles the efficiency of the traditional approach. The validity of the algorithm is argued through theoretical analysis and experiments. 【Key words】machine translation; local alignment; compensation; parallel corpora
