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 分別利用了改進(jìn)的隱馬爾可夫模型( hiddenmarkovmodel , hmm )和條件隨機(jī)域模型( conditionalrandomfield , crf )兩種方法進(jìn)行英文命名實(shí)體的識別,并對實(shí)驗(yàn)結(jié)果進(jìn)行了分析。
