</SectionTitle>
    <Paragraph position="0"> In this paper, a pattern-based approach to the paraphrasing of Chinese utterances is proposed and a method of constructing paraphrasing patterns from a corpus is described. Based on the proposed approach and method, a paraphraser is implemented and four types of paraphrasing patterns are constructed. Also, a paraphrasing experiment is conducted and experimental results are reported. The proposed approach has the following advantages.</Paragraph>
    <Paragraph position="1"> (1) Because only morphological analysis is required, it is easy to implement the paraphraser and the processing time is short.</Paragraph>
    <Paragraph position="2"> (2) By using the developed semi-automatic generalization tool, paraphrasing patterns can be efficiently learned from a paraphrasing corpus and human experience. The patterns enhanced by human experience have a higher accuracy.</Paragraph>
    <Paragraph position="3"> (3) The classification of paraphrasing phenomena in pattern learning makes it possible to restrict the paraphrasing process to some language phenomena. The mechanism of applying different types of patterns emphasizes how to raise the accuracy of paraphrasing and how to increase variations.</Paragraph>
    <Paragraph position="4"> In this research, only four types of paraphrasing phenomena are involved. The coverage achieved using the current patterns is still low. In the next phase, we are going to use the proposed approach on other paraphrasing phenomena in order to be able to paraphrase more Chinese utterances.</Paragraph>
