Constituency Tree Labeling Tool

The purpose of this package is to solve the constituency tree labeling problem.

Look from the dataset labeled by NLTK,it is a bit counter-intuitive and it is very troublesome to label.

Then this package provides a LabelTree, you can use this class to generate dataset, for example, convert example1 and convert example2, and then use the label_tree_to_nltk method to convert them into data conforming to the NLTK label format.

成分分析树标注工具

这个包的目的在于标注成分分析树。

从nltk标注出来的数据集来看，有点反直觉，标注起来很麻烦。 那么此包提供一个LabelTree，您可以通过这个类来生成例如convert example1以及convert example2，然后通过label_tree_to_nltk方法将其转换成符合nltk标注格式的数据出来。
