An HPSG-to-CFG Approximation of Japanese
3 Proceedings of the 18th International Conference on Computational Linguistics (COLING'00), July 31 - August 4 volume 2, Pages 1046-1050, Morgan Kaufmann Publishers, Saarbr, 2000
We present a simple approximation method for turn- ing a Head-Driven Phrase Structure Grammar into a context-free grammar. The approximation method can be seen as the construction of the least fixpoint of a certain monotonic function. We discuss an ex- periment with a large HPSG for Japanese.
