| Abstract(in English) | A uniquely parsable grammar (UPG) introduced by Morita et al. is a grammar with a restricted type of rewriting rules, where parsing can be performed without backtracking. It has been shown that the class of UPGs and its three subclasses form a "deterministic Chomsky hierarchy" parallel to the classical Chomsky hierarchy. In this paper, we extend it to a uniquely parsable unification grammar (UPUG). A unification grammar (UG) is a system in which nonterminal symbols are terms, and derivation processes accompany unification of terms as in prolog. We first define a general framework of a UG, and then give a UPUG-condition so that it has the property of unique parsability. |
