      ABSTRACT = {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.},
