ABSTRACT
This paper proposes an LR parsing
algorithm modified for grammars with
feature-based categories. The proposed
algorithm does not instantiate categories...

Abstract
We present a new LR algorithm for tree-
adjoining grammars. ... alternative to an
existing algorithm that is shown to be incorrect.
Furthermore, the new algorithm is much sim-
