LUI Constituent Trees

Grammars often produce numerous tree structures for any input parsing or generation request. When a parse is performed, LUI displays a summary containing one tree per reading assigned by the grammar. The summary view looks like this:

Depending on personal preferences, the summary view of the trees may be too small for intensive work. Clicking on a tree's background pulls that tree out into its own window, and enlarges it:

Nodes in trees highlight when the user mouses over them, indicating that the mouse buttons are active. The nodes in the summary and detail views function identically; the only difference is size. Left-clicking on a tree node brings up the associated AVM; right-clicking requests a popup-menu with the following choices:

Menu Item Description
Full AVM Brings up the AVM associated to this node, before the grammar's restrictor has been applied.
Local AVM Brings up the AVM associated to this node, after the grammar's restrictor has been applied.
Chart Edges Highlights the edges used in or built on this node in a parse chart browser.
Partial Chart Opens a parse chart browser containing only those edges used in or built on this node.
Generate Attempts to generate sentences using the grammar whose semantics match those of the selected node.
Rephrase Same as Generate, but also applies transfer rules to the semantics (?).
Simple MRS Opens an MRS browser for the simple view of the semantics of this node.
Indexed MRS Opens an MRS browser for the indexed view of the semantics of this node.
Scoped MRS Opens an MRS browser for the scoped view of the semantics of this node.
Dependencies Displays the dependencies view of the semantics of this node.
