摘要
在CRF模型下,进行单字标注和单元词标注的识别效果和识别效率的比较;实验结果表明,单字标注在付出更长运行时间的代价下,较单元词标注识别效果更佳;此外,还研究特征数量对实验效果的影响。
This article uses the model of CRF to conduct an experiment for comparing recognition performance and recognition efficiency between the way based on char labeled and the way based on word labeled. The experiment result shows that the performance of based on char is better than that of based on word at the expense of costing more time. In addition, it also pays more attention to the quantity of feature＇s influence on the experiment performance.
