I am in need of a program that: 1) visualizes bracket-format trees into images; 2) allows modification of the tree structure on that image; 3) modifications on the image will be automatically reflected in the bracket-format trees.
The bracketed tree look like this:
[S [NP Trump][VP [V likes][NP Twitter]]]
The visualization using that program looks like this:
The reason I wanted this program is that, when the tree gets very complicated, it's very hard to modify the brackted tree because there are too many brackets to keep track of.
So the main thing I want is to be able to modify the tree in the visualization (say change "likes" to "hates") and the change is reflected in the bracketed format because that will later be processed for other purposes.
Any help is greatly appreciated!
