Linguistic Tree Constructor 2.7.1

Linguistic Tree Constructor is a free program for building linguistic syntax trees from text. Linguistic Tree Constructor lets the user build the tree in a point-and-click fashion.
The program does no analysis on its own -- the user is completely free to draw the tree however he or she wishes. However, the program makes sure that the tree is a tree and not some other kind of graph.
Syntactic theories supported
Three "flavors" of trees are supported:
- "Generic" syntax trees,
- X-Bar syntax trees
