摘要

从理论和经验的角度来看，描述话语中的内隐现象是一个有问题的任务。本文通过对同一文本上两种突出的话语关系(连贯关系)注释方法进行新颖的比较分析，为这一主题做出了贡献。我们比较了宾州语篇树库2.0中隐式关系的注释，即没有显语篇连接语的语篇关系，与RST信号语料库(RST- sc)中最近发布的修辞关系信号分析。对应关系对的交集很小，但有一个明显的趋势:与st - sc的整体信号分布不同，所研究的交集中超过一半的信号是语义型的，大部分是由松散定义的词汇链构成的。我们的数据转换允许同时描述和详细研究这两种资源。

Signalling Implicit Relations: A PDTB - RST Comparison

Describing implicit phenomena in discourse is known to be a problematic task, from both theoretical and empirical perspectives. The present article contributes to this topic by a novel comparative analysis of two prominent annotation approaches to discourse relations (coherence relations) that were carried out on the same texts. We compare the annotation of implicit relations in the Penn Discourse Treebank 2.0, i.e. discourse relations not signalled by an explicit discourse connective, to the recently released analysis of signals of rhetorical relations in the RST Signalling Corpus (RST-SC). The intersection of corresponding pairs of relations is rather a small one, but it shows a cleartendency: unliketheoverallsignaldistributionintheRST-SC,morethanhalfofthesignalsin the studied intersection are of semantic type, formed mostly by loosely deﬁned lexical chains. Our data transformation allows for a simultaneous depiction and detailed study of the two resources.

期刊介绍： D&D seeks previously unpublished, high quality articles on the analysis of discourse and dialogue that contain -experimental and/or theoretical studies related to the construction, representation, and maintenance of (linguistic) context -linguistic analysis of phenomena characteristic of discourse and/or dialogue (including, but not limited to: reference and anaphora, presupposition and accommodation, topicality and salience, implicature, ---discourse structure and rhetorical relations, discourse markers and particles, the semantics and -pragmatics of dialogue acts, questions, imperatives, non-sentential utterances, intonation, and meta--communicative phenomena such as repair and grounding) -experimental and/or theoretical studies of agents'' information states and their dynamics in conversational interaction -new analytical frameworks that advance theoretical studies of discourse and dialogue -research on systems performing coreference resolution, discourse structure parsing, event and temporal -structure, and reference resolution in multimodal communication -experimental and/or theoretical results yielding new insight into non-linguistic interaction in -communication -work on natural language understanding (including spoken language understanding), dialogue management, -reasoning, and natural language generation (including text-to-speech) in dialogue systems -work related to the design and engineering of dialogue systems (including, but not limited to: -evaluation, usability design and testing, rapid application deployment, embodied agents, affect detection, -mixed-initiative, adaptation, and user modeling). -extremely well-written surveys of existing work. Highest priority is given to research reports that are specifically written for a multidisciplinary audience. The audience is primarily researchers on discourse and dialogue and its associated fields, including computer scientists, linguists, psychologists, philosophers, roboticists, sociologists.
