Linguistic Tree Constructor

Linguistic Tree Constructor is an application for drawing linguistic syntax trees. Its main strength is assisting in data production by quickly analyzing large amounts of text. "Generic" trees are supported, as well as RRG and X-Bar trees. Node-categories are user-definable, and additional user-definable labels can also be applied to each node. Publication-quality, high-resolution, horizontal trees can be drawn. The file format is based on TIGER-XML.
