基于FST的印地语词法分析器
FST Based Morphological Analyzer for Hindi Language
摘要:
印地语是一种高度屈折的语言,基于FST(有限状态转换器)的方法是最有效的开发这种语言的形态分析器。本文提出的工作使用SFST(斯图加特有限状态传感器)工具生成FST。创建了一个词根词典。然后添加规则,用于从这些词根生成屈折词和派生词。所开发的词形分析器用于基于Stanford POS Tagger的词性标注器。该系统首先使用人工标注的语料库进行训练,然后使用Stanford POS tagger的MAXENT(最大熵)方法对输入句子进行标注。形态分析仪给出了大约97%的正确结果。POS tagger对于具有训练模型文件已知的单词的句子给出了大约87%的准确度,并且对于具有训练模型文件未知的单词的句子给出了80%的准确度。
英文摘要:
Hindi being a highly inflectional language, FST (Finite State Transducer) based approach is most efficient for developing a morphological analyzer for this language. The work presented in this paper uses the SFST (Stuttgart Finite State Transducer) tool for generating the FST. A lexicon of root words is created. Rules are then added for generating inflectional and derivational words from these root words. The Morph Analyzer developed was used in a Part Of Speech (POS) Tagger based on Stanford POS Tagger. The system was first trained using a manually tagged corpus and MAXENT (Maximum Entropy) approach of Stanford POS tagger was then used for tagging input sentences. The morphological analyzer gives approximately 97% correct results. POS tagger gives an accuracy of approximately 87% for the sentences that have the words known to the trained model file, and 80% accuracy for the sentences that have the words unknown to the trained model file.
