Syntax tree editor for rapid annotation of existing text
Linguistic Tree Constructor (LTC) is a tool for drawing lingusitic syntax trees of already-existing text.
It is a syntax editor, not a text editor, so the text has to exist already. It is best suited for large-scale, rapid creation of hand-annotated treebanks.
The user can define their own node categories, and can label each node with labels, also definable by the user.
TreeForm Syntax treedrawing software is a Linguistic Syntax/Semantics treedrawing editor. Designed for graphical n-ary treedrawing. Mac users can install the software through the new package, but must give authority through "System Preferences" > "Security & Privacy". Windows and Linux users can run the software through the JAR file directly. All users must have Java 8 or higher installed. https://java.com/en/download/
