We describe Turkish Discourse Bank 1.2, the latest version of a discourse
corpus annotated for explicitly or implicitly conveyed discourse relations,
their constitutive units, and senses in the Penn Discourse Treebank style. We
present an evaluation of the recently added tokens and examine three commonly
occurring dependency patterns that hold among the constitutive units of a pair
of adjacent discourse relations, namely, shared arguments, full embedding and
partial containment of a discourse relation. We present three major findings:
(a) implicitly conveyed relations occur more often than explicitly conveyed
relations in the data; (b) it is much more common for two adjacent implicit
discourse relations to share an argument than for two adjacent explicit
relations to do so; (c) both full embedding and partial containment of
discourse relations are pervasive in the corpus, which can be partly due to
subordinator connectives whose preposed subordinate clause tends to be selected
together with the matrix clause rather than being selected alone. Finally, we
briefly discuss the implications of our findings for Turkish discourse parsing.

本文描述了土耳其话语库 1.2 版本，介绍了一项新添加的评估，分析了构成单元之间的三种常见依存模式，发现隐含关系比显性关系更常见，两个相邻的隐含话语关系一起使用的频率比显式关系更高，并且存在全嵌入和部分包含的话语关系。
