【摘要】：蒙古语语义角色标注是浅层语义分析的一种实现方式,也是从浅层语义分析到深层语义分析的必经之路。论文从蒙古语依存树库中选取5087个简单动词谓语句,抽取施事和当事的特征,归纳施事和当事的识别规则,进行了施事和当事的自动标注。自动标注的召回率为87.62%,准确率为93.0%。全文由导论、主要章节、结论等部分组成。导论部分,阐述了选题意义、研究概况、研究对象,研究目标、方法和语料来源。第一章,介绍了基于依存语法的蒙古语语义角色分类及其标记的确定和标注的具体步骤。第二章,基于标注依存关系语料,根据依存关系、词性分类、语义分类、词语搭配,对蒙古语施事和当事的特征进行了归纳研究。第三章,基于蒙古语依存关系,归纳了蒙古语施事和当事的识别规则。第四章,进行了蒙古语施事和当事的自动标注,分析了标注结果并提出了存在的问题以及解决方法。结论部分,总结全文并提出了今后要研究的问题。
[Abstract]:Mongolian semantic role tagging is not only a way to realize shallow semantic analysis, but also a necessary way from shallow semantic analysis to deep semantic analysis. In this paper, 5087 simple verb predicate sentences are selected from Mongolian dependency tree database. The characteristics of agents and parties are extracted, and the identification rules of agents and parties are summarized. The automatic labeling of agents and parties is carried out. The recall rate of automatic tagging is 87.62, and the accuracy is 93.0. The full text is composed of introduction, main chapter, conclusion and so on. The introduction describes the significance of the topic, research overview, research objects, research objectives, methods and data sources. The first chapter introduces the semantic role classification of Mongolian language based on dependency grammar and the steps of identifying and tagging its markers. The second chapter, based on the tagging dependency corpus, induces and studies the Mongolian agent and the characteristics of the parties according to the dependency relation, the classification of parts of speech, the semantic classification, the collocation of words. In chapter three, based on the dependence of Mongolian language, the identification rules of Mongolian agents and parties are summarized. In chapter 4th, the Mongolian agent and the parties are annotated automatically, the results are analyzed and the existing problems and solutions are put forward. The conclusion part summarizes the full text and puts forward the problems to be studied in the future.
