A large scale manually annotated Chinese corpus and a number of well-conducted experiments were used to identify the following points of the hidden Markov model based part-of-speech tagging scheme for Chinese texts. The results are:① The Bigram model is better than the Trigram model in terms of the performance-cost ratio.② An annotated corpus of about 70000 words tokens would be sufficient for training the Bigram model, to produce system performance of about 93% tagging accuracy for ambiguous word tokens and 97% tagging accuracy for all word tokens in the texts.③ The Bigram model can be suited to different application domains quite well.

论文在经过人工分词和词类标注的大规模汉语语料库的支持下，通过一系列对比实验，对基于隐Markov模型的汉语词类自动标注算法进行了系统的考察，并得出结论：① Bigram模型的"性能价格比"较Trigram模型更令人满意；②以7万词次左右的标注语料库训练Bigram模型即已基本够用（此时，兼类词词类标注正确率及文本词类标注正确率分别可达93%和97%以上）；③ Bigram模型对不同领域具有一定的适应性。

Based on investigations of 40, 000 words, this dissertation discusses the subject from both a theoretical and a practical approach and puts forward a set of concrete and exercisable criteria of classification.

在英译汉过程中，有些句子可以逐词对译，有些句子则由于英汉两种语言的表达方式不同，就不能逐词对译，只能将词类进行转译之后，方可使译文显得通顺、自然；对词类转译技巧的运用须从四个方面加以注意。

英汉词类较为明显的差异有：英语使用动词较少，有很多动作体现在名词和介词等词类中，而汉语却大量使用动词。

Auxiliary words of Chinese are a special parts of speech, it includes auxiliary word of the structure , the auxiliary word of the tense , auxiliary word of tone ,etc., although English does not have a position noun in this kind of 3 Chinese nouns of auxiliary word and has places applicable to all with the preposition of English on semanteme Compare in quantity, can find different characteristics of the Chinese-English parts of speech : It is relatively less in quantity in Chinese that 1 prepositions and conjunctions lack 2 adverbial words in many Chinese of English Analyse Chinese multi-purpose verb and multi-purpose noun of English from frequency that the parts of speech use.

2汉语的助词是个特殊的词类，它包括结构助词、时态助词、语气助词等，英语虽无此类助词3汉语名词中的方位名词在语义上与英语的介词有共通之处从数量上比较，也可发现汉英词类的不同特点：1介词与连词都是英语多汉语少2副词在汉语中数量相对较少从词类使用的频率上分析，汉语多用动词而英语多用名词。

Category : parts of speech and function, such as the classification of words in terms of parts of speech, the identification of functions of words in term of subject, predicate, etc.
