【摘要】：藏文信息處理的研究內(nèi)容和對象極為廣泛,其中藏文副詞的研究是藏文信息處理領域基礎性課題之一,只有長期的基礎研究才能有樂觀的發(fā)展前景。與語言信息處理相關的機器翻譯是最典型、最有價值的應用系統(tǒng)。從機器翻譯系統(tǒng)的基本模型來看,最關鍵和最基礎的部分是句法分析和語義分析,而句法分析是以靜態(tài)語言知識庫為支撐的。語言知識庫包括詞典、語法規(guī)則、語法信息詞典等。其中副詞是非常重要的一個詞類。更為重要的是藏文副詞在詞法、句法中的地位和意義是非常重要,因此面向信息處理的藏文副詞研完是藏文信息處理領域的重要內(nèi)容之一,對語言智能化研究具有重大意義。 本文從藏文信息處理的角度對藏文的副詞進行了探討。在藏文副詞現(xiàn)有研究成果的基礎上,借鑒了《現(xiàn)代漢語語法信息詞典》的設計思路。主要采用以屬性描述為主,分類與屬性描述相結合的方法。從多角度對藏文副詞屬性庫進行研究,從藏文副詞的形態(tài)結構、句法功能和語義信息等多個層面上挖掘出藏文副詞的13項屬性特征。即副詞的子類,修飾動詞,修飾形容詞,傳統(tǒng)語法,復合副詞,同屬兼類,形副,重復,前置,后置,兼類詞,古詞,重疊。其中形副,重疊,重復,前置,后置,復合副詞六種形態(tài)結構是從藏文副詞構詞成分上的劃分；而程度、范圍、時間、肯定、情態(tài)、否定、關連、語氣、重復和疑問副詞等10個子類是從藏文副詞自身功能上的劃分；古詞,兼類詞,同屬兼類三種歸屬于藏文副詞語義信息上的劃分。副詞最大的特點是能夠修飾動詞和形容詞。另外,從藏文副詞的語法功能來分析,副詞跟藏文傳統(tǒng)語法有著密切關系。 在技術上,副詞屬性庫采用成熟的關系數(shù)據(jù)庫(在Microsoft Excel環(huán)境下實現(xiàn))文件格式詳細描述藏文副詞及其語法屬性的二維關系。設立屬性字段13個,描寫藏文副詞共169個。結合藏文副詞的特點研究藏文副詞的各種屬性從而構建了藏文副詞屬性庫,可以擴大藏文知識庫建設的規(guī)模。其直接目的是為藏文副詞的語義分析服務。
[Abstract]:Tibetan information processing has a wide range of research contents and objects, among which the study of Tibetan adverbs is one of the basic topics in Tibetan information processing. Only long-term basic research can have an optimistic development prospect. Machine translation related to language information processing is the most typical and valuable application system. From the view of the basic model of machine translation system, the most important and basic part is syntax analysis and semantic analysis, and syntax analysis is supported by static language knowledge base. The language knowledge base includes dictionaries, grammar rules, grammar information dictionaries and so on. Adverb is a very important category of words. What is more important is the position and significance of Tibetan adverbs in lexicon and syntax. Therefore, the completion of Tibetan adverbs oriented to information processing is one of the important contents in Tibetan information processing, and it is of great significance to the study of language intelligence. This paper discusses the adverbs in Tibetan language from the point of view of Tibetan information processing. Based on the existing research results of Tibetan adverbs, this paper draws lessons from the design ideas of Modern Chinese Grammar Information Dictionary. The main methods are attribute description, classification and attribute description. This paper studies the attribute database of Tibetan adverbs from many angles, and excavates the 13 attribute features of Tibetan adverbs from the aspects of the morphological structure, syntactic function and semantic information of Tibetan adverbs. That is, the subcategory of adverbs, modified verbs, modified adjectives, traditional grammar, compound adverbs, both genus and category, form and parataxis, repetition, preposition, postposition, both-class words, ancient words, overlapping. Among them, the six forms and structures of the adverbs, which are overlapping, repeating, prepositional, postpositional and compound adverbs, are divided from Tibetan adverbs on the components of word formation. Ten subcategories, such as degree, scope, time, affirmation, modality, negation, relevance, mood, repetition and interrogative adverbs, are classified from the function of Tibetan adverbs themselves. Ancient words, both generic and generic words, belong to the division of the semantic information of Tibetan adverbs. The biggest feature of adverbs is the ability to modify verbs and adjectives. In addition, from the grammatical function of Tibetan adverbs, adverbs are closely related to Tibetan traditional grammar. Technically, the adverb attribute database uses a mature relational database (implemented under the Microsoft Excel environment) file format to describe in detail the two-dimensional relationship between Tibetan adverbs and their grammatical attributes. There are 13 attribute fields and 169 adverbs describing Tibetan. According to the characteristics of Tibetan adverbs, this paper studies the attributes of Tibetan adverbs and constructs the attribute database of Tibetan adverbs, which can enlarge the scale of the construction of Tibetan knowledge base. Its direct purpose is to serve the semantic analysis of Tibetan adverbs.
