以下是来自Ontonotes - V3.0的句子示例。我希望知道Treebanked句子中* T * -1和* -2的含义[我认为这是普通句子的标记化版本]

简单句子:

In the summer of 2005, a picture that people have long been looking forward to
started emerging with frequency in various major Hong Kong media.

Treebanked句子:

[Speaker#1] In the summer of 2005 , a picture that people have long been looking
forward to *T*-1 started *-2 emerging with frequency in various major Hong Kong
media .

还有一些其他标签,如* PRO *和* PRO * -1

答案 0 :(得分:3)

*T*-1事物表示解析树中的“跟踪”。你看到它们的原因是OntoNotes建立在使用该注释的Penn Treebank上。

如果你在网上搜索“penn treebank trace”,你会发现很多东西可以阅读。我找到了this文档,其中包含Penn Treebank中各种*X*标记的简短说明和示例,但可能有更完整的解释。
