基于条件随机场模型的蒙古文地名自动识别研究

Research on Mongolian Place Names Recognition Based on CRF

根据蒙古文地名的特点,引入词性特征、字典特征、实体指示词特征以及外文地名用词特征,基于条件随机场模型对蒙古文地名自动识别问题进行研究.结果表明,该模型对蒙古文地名识别的准确率为95.45%,召回率为79.41%,F值为86.70%.

According to the characteristics of Mongolian place names,the introduction of part-of-speech features,dictionary features,entity indicator features,and foreign language place names is used.Based on the conditional random field model,the automatic identification of Mongolian place names is studied.The results show that the accuracy of the model in identifying Mongolian place names is 95.45%,the recall rate is 79.41%,and the F value is 86.70%.
