Abstract
Introduction We describe the development of XHPSG, a large-scale English grammar in the HPSG formalism translated from the XTAG grammar (The XTAG Research Group, 1995). Our goal is to obtain a large-scale, linguistically sound grammar for our HPSG parser (Makino et al., 1998) with a relatively small workload. For this purpose, we try to make an HPSG grammar equivalent to the XTAG grammar in the strong sense where we preserve the structures and the linguistic analysis of the XTAG grammar. To guarantee the equivalence of the XHPSG and XTAG grammars, the following conditions must be satisfied: 1) An XTAG elementary tree is translated to an XHPSG lexical item that translates back to the original elementary tree by applying the schemata and principles; 2) No XHPSG lexical item translates back to a tree other than the original XTAG elementary tree; 3) Substitution and adjunction allowed in the original grammar, and no other opeations, are simulated in the XHPSG parsing.
