In this thesis , attention is concentrated on the english ner . ner is implemented with two methods , which are improved hmm and conditional random field , and the test result is analyzed . first , this thesis identifies the english named entity with improved hmm 分别利用了改进的隐马尔可夫模型( hiddenmarkovmodel , hmm )和条件随机域模型( conditionalrandomfield , crf )两种方法进行英文命名实体的识别,并对实验结果进行了分析。
