In an ordinary syntactic parser, the input is a string, and the grammar ranges over strings. This paper explores generalizations of ordinary parsing algorithms that allow the inpu...
For many educational applications such as learning tools for argumentation, structured diagrams are a suitable form of external representation. However, student-created graphs pos...

One aim of tool integration is designing an integrated development environment that accesses the data/models of different tools and keeps them consistent throughout a project bein...
We develop a framework for formalizing semantic construction within grammars expressed in typed feature structure logics, including HPSG. The approach provides an alternative to t...
efined abstract representation of a semantic path that respects the ontological classes of a particular semantic network. A discrete "walker" utilizes the grammar to dete...
