P94-1030 The method is also applicable to head-driven derivation , which is more general than
P94-1030 algorithm , from the consideration of head-driven derivation , the index of a formula is determined
P94-1030 DCG is just a special case of head-driven derivation , in which the input string is
P94-1030 recomputing partial results , head-driven derivation will face the same problem when
P94-1030 and finally conclude the paper . Head-driven Derivation Pereira and Warren showed that
P94-1030 parsing . We call this derivation head-driven derivation , which is depicted as follows
P94-1030 Akker , 1993 ) can be seen as head-driven derivation , when the semantic-head/syntactic-head
P94-1030 between leftcorner parsing and head-driven derivation , lexicons are the terms that
P00-1008 t. Like in Markov Grammars , a head-driven derivation generates first a head-role T-gram
