目前，许多自然语言研究人员将注意力转向树库开发，并试图在其表示格式中实现准确性和语料库数据覆盖率。本文提出了一种数据驱动的注释模式，确保数据覆盖率和语言现象之间的注释一致性的意大利树库。该模式是一种基于依赖关系的格式，以谓词-论元结构的概念为中心，用痕迹来表示不连续的成分。树库的开发涉及到一个注释过程，该过程由一个交互式解析工具帮助人类注释者执行，该工具逐步构建句子的句法表示。为了增加这个解析器的语法知识，一个特定的数据驱动的策略已被应用。我们描述了注释模式的周期性发展，强调了格式的丰富性和灵活性，并提出了一些代表性问题。
Many natural language researchers are currently turning their attention to treebank development and trying to achieve accuracy and corpus data coverage in their representation formats. This paper presents a data-driven annotation schema developed for an Italian treebank ensuring data coverage and consistency between annotation of linguistic phenomena. The schema is a dependency-based format centered upon the notion of predicate-argument structure augmented with traces to represent discontinuous constituents. The treebank development involves an annotation process performed by a human annotator helped by an interactive parsing tool that builds incrementally syntactic representation of the sentence. To increase the syntactic knowledge of this parser, a specific data-driven strategy has been applied. We describe the cyclical development of the annotation schema highlighting the richness and flexibility of the format, and we present some representational issues.
