Generating Chinese Couplets and Quatrain Using a Statistical Approach

We propose a novel statistical approach to automatically generate Chinese couplets and Chinese poetry. For Chinese couplets, the system takes as input the first sentence and generates as output an N-best list of second sentences using a phrase-based SMT model. A comprehensive evaluation using both human judgments and BLEU scores has been conducted and the results demonstrate that this approach is very successful. We then extended this approach to generate classic Chinese poetry using the quatrain as a case study. Given a few keywords describing a user's intention, a statistical model is used to generate the first sentence. Then a phrase-based SMT model is used to generate the other three quatrain sentences one by one. Evaluation using human judgment over individual lines as well as the quality of the generated poem as a whole demonstrates promising results.
