摘　　要：依存语法又称"从属关系语法",研究句子各构成成分之间的支配和从属关系。依存结构是指句子中词与词之间的句法结构关系,该结构以树状结构进行描述,被称之为依存结构树库。文章以依存语法的理论框架作为藏语树库构建的理论指导,充分借鉴依存语法的思想精髓,结合藏语语法体系,设立出符合藏语语法体系的句法和语义标注关系体系,设计了判别式的句法分析算法,从而构建了多维视窗的藏语依存树库。具体分析时,首先,对依存语法的由来、定义、依存关系的适用性等背景知识做了简要的阐释;其次,在藏语句子的筛选、藏语依存结构的形式化模型、藏语依存的骨架结构以及藏语依存树的多维关系等方面进行了研究和分析。Dependency grammar also called ＂subordinate relationship grammar＂, and it research on the relation-ship between the dominant and subordinate constituents of a sentence. Dependency structure refers to the syntac-tic relations between the words in the sentence and the structure described in a tree structure, called for depen-dency treebank. The theoretical framework of dependency grammar as the theoretical guidance for the Tibetantreebank construction, fully drawing ideological essence of dependency grammar and combining with Tibetangrammar system, a syntactic and semantic tagging system in line with the Tibetan grammar system was set upand the discrimination of the syntax analysis algorithm was designed in order to building a Tibetan dependencytreebank of multidimensional windows. In the specific analysis, first of all, the background knowledge was brieflyexplained in terms of the dependency grammar origin, definition and the applicability of dependency relation-ship, secondly, the selection of Tibetan sentences, formal model of dependency structure, dependency frameworkstructure and multidimensional relationship of Tibetan dependency tree were analyzed as well.
