为了解决文本时间表达式的识别与规范化问题，针对时间表达式在形式上的多样性与非结构化，提出了对时态元素进行刻画的思想，划分时间表达式类别及规范形式；在此基础上，采用正则表达式与Trie树结构相结合的方式构建出时间短语识别树，自动进行中文时间表达式的识别与分类；最后，提出规范化算法与修正算法处理识别后的结果，得到规范化形式。以中文语料进行实验，中文表达式识别与规范化工作达到较好的效果。

Concerning the problem with the recognition and normalization of time expressions in texts , ai-ming at the diversity and unstructured forms of time expressions , it proposed the idea of describing tempo-ral elements to divide the types of time expressions and their forms of normalization .With the method that combined regular expressions with Trie tree structure , it built the recognition tree of time expressions , which could recognize time expressions automatically .Finally, it proposed the normalization algorithm and correction algorithm to deal with the recognized results .The results are pretty good .
