Abstract

This paper proposes an LR parsing algorithm modified for grammars with feature-based categories. The proposed algorithm does not instantiate categories during preprocessing of a grammar as proposed elsewhere. As a result, it constructs a minimal size of GOTO/ACTION table and eliminates the necessity of search for GOTO table entries during parsing.
