There are two main technologies in time expression recognition:sequence labeling method based on machine learning theory and rule-based method.

我们的方法是将简称生成问题转化为等价的序列标注问题,并利用一阶条件随机场建立自动生成模型。
In our method, we transformed the problem into an equivalent sequence tagging problem, and built up the automatic generation model through the first order conditional random field.
