1、石家莊經(jīng)濟(jì)學(xué)院本科生畢業(yè)論文摘要中文分詞是信息提取、信息檢索、機(jī)器翻譯、文本分類、自動(dòng)文摘、語(yǔ)音識(shí)別、文本語(yǔ)音轉(zhuǎn)換、自然語(yǔ)言理解等中文信息處理領(lǐng)域的基礎(chǔ)，雖然研究了很多年，但是中文分詞依然是中文信息處理的瓶頸之一。本文首先將已有的分詞算法進(jìn)行了分析、總結(jié)和歸納，討論了中文識(shí)別一直難以很好解決的兩大問(wèn)題：歧義識(shí)別和未登錄詞。接著在基于詞典的基礎(chǔ)上將最大正向匹配和最大逆向匹配結(jié)合起來(lái)，得到了雙向匹配分詞算法，并且使用了自己提出的字典機(jī)制（子字典機(jī)制）實(shí)現(xiàn)了一個(gè)基于雙向匹配算法的中文分詞系統(tǒng)。關(guān)鍵詞：中文分詞；雙向匹配；子字典機(jī)制ABSTRACTChinesew
