| 摘 要： | 藏语是语序非常灵活的一种语言,藏语词法分析和句法分析等浅层研究不能很好地满足藏语自然语言理解的需求。从简单句型的藏语句子出发,研究了基于投射的藏语语义依存分析,构建了藏语语义依存树库,设计了语义依存弧类型分析特征模板。最后通过最大熵分类模型,对人工分析过的语义依存弧的句子进行依存弧的类型分析并进行标注,为今后的语义依存分析提供新的思考视角和更好的理论支撑。

| Abstract: | Tibetan is a language with very flexible word order. Current research such as Tibetan lexical analysis and syntactic analysis cannot meet the needs of Tibetan natural language understanding. Based on the simple sentence pattern of Tibetan sentences, we study the semantic dependence of Tibetan based on projection, construct a Tibetan semantic dependency tree library, and design a semantic dependency arc type analysis feature template. Finally, the semantically dependent arc sentences of the artificial analysis are analyzed and labeled through the maximum entropy classification model, which provides a new perspective and sound theoretical support for future semantic dependence analysis. |
