The two main focuses of this project are
The project cooperates closely with the Pargram project, also using the Xerox Linguistic Environment as its development platform.
In the past, pressure of time has often kept projects of broad-coverage grammar development from going into the assessment of different alternatives of analyzing a particular phenomenon, or the refinement and publication of methods for extending, maintaining, testing and optimizing grammar code.
The B12 project addresses these issues explicitly. For selected phenomena, the effect of adapting different analyses is investigated: which linguistic generalizations are captured, how maintenance is affected, what interactions occur, etc.
Closely related to such experiments is the work on providing tools and procedures to technically ensure controlled comparisons, and for evaluating the results. This includes among other things
