Overview

The Linguistic User Interface (LUI) is an on-going project to build a visualization tool for the most common object types in constraint-based grammars, i.e. trees, feature structures, MRSs, charts, et al. While the LKB comes with built-in browsers for all of these, the current use of the CLIM (Common-Lisp Interface Manager) toolkit in the LKB severely limits portability and ease of use (and programmatic extension). Thus, portability and royalty-free delivery are among the primary motivations for the LUI project; at the same time, LUI attempts to `conservatively' improve over the existing LKB tools, for example in terms of layout options, scalability, user parameterization, display effiency. While preserving all existing LKB display functionality, LUI adds some new facilities, including drag-and-drop interactive unification, display of, and navigation through multiple feature structure incompatibilities, and creation of screen dumps in (for now) PostScript or !LaTeX formats.

LUI is an application of the [http://yz-windows.sourceforge.net/ YZ Windows] API, developed mainly by WoodleyPackard, who is also the main LUI developer (with LKB-side support by StephanOepen).
