CI: ADDO-EN: Significant Enhancement of the Exisitng Penn Discourse Treebank

构建大规模的标注资源是自然语言处理基础研究和应用研究的关键。我们这个项目的主要长期目标是对现有的独特资源-宾夕法尼亚大学话语树库(PDTB)进行非常实质性的扩展，该资源是在之前的NSF支持下开发的，用各种新的注释来增强它，以及提炼早期的注释。我们提出的工作包括进行一些新的标注和一些试点实验来确认增强策略。另一个目标是将这一资源的潜在用户的不同部分聚集在一起，首先让他们熟悉这一资源的潜力，并获得他们的反馈，以指导进一步的扩充。已经申请了PDTB来执行总结任务。未来的应用将在信息提取、问题生成和机器翻译等领域。在理论方面，我们的资源将被证明是有用的，以增加对语言的语篇结构的理论理解。

Building large scale annotated resources is crucial for basic and applied research in Natural Language Processing (NLP). Our major long term goal of this project is to make very substantial extensions to an existing unique resource, the Penn Discourse Treebank (PDTB), developed under prior NSF support, augmenting it with a variety of new annotations as well as refining earlier annotations. Our proposed work involves conducting some new annotations and some pilot experiments to confirm the strategies for augmentation. A further goal is to bring together a cross section of potential users of this resource, first to acquaint them with the potential of this resource as well as to get their feedback for guiding further augmentations. Applications of PDTB for the task of summarization have already been made. Future applications are in the areas of information extraction, question-generation, and machine translation among others. On the theoretical side, our resource will prove useful in increased theoretical understanding of discourse structure of language.
