本文介绍了汉语话语树库，一个语料库注释Penn话语树库风格的话语关系，采取的形式是一个谓词带两个参数。我们首先描述了汉语话语联系语的句法和统计分布以及汉语标点符号在话语标注中的作用，然后描述了我们如何基于此描述设计我们的标注策略流程。本文的注释策略具有以下特点：一次注释显性和隐性话语关系;根据语义而非句法的理由定义论元标签;直接注释隐性话语关系的语义类型。我们还介绍了一个扁平的，11值的语义类型分类计划的话语关系。最后，我们通过评估结果证明了我们方法的可行性。
The paper presents the Chinese Discourse TreeBank, a corpus annotated with Penn Discourse TreeBank style discourse relations that take the form of a predicate taking two arguments. We first characterize the syntactic and statistical distributions of Chinese discourse connectives as well as the role of Chinese punctuation marks in discourse annotation, and then describe how we design our annotation strategy procedure based on this characterization. The Chinese-specific features of our annotation strategy include annotating explicit and implicit discourse relations in one single pass, defining the argument labels on semantic, rather than syntactic, grounds, as well as annotating the semantic type of implicit discourse relations directly. We also introduce a flat, 11-valued semantic type classification scheme for discourse relations. We finally demonstrate the feasibility of our approach with evaluation results.
