Abstract: In this paper we describe a hypertext translator-generator system that uses ChiTed, the visual Petri net editor from the ChiTrellis hypertext system, to specify the semantic component of a string-to-graph translation. ChiTed-specified parsers convert general authoring notations into structured ChiTrellis documents for browsing. The operative mechanism is termed a pair grammar, in which a string grammar and a graph grammar are paired in a one-to-one correspondence. When a ChiTed-specified parser reduces by one of its string grammar productions, the corresponding production in its graph grammar is used to generate a portion of the Petri net that implements that syntax. The use of pair grammars in conjunction with the Trellis model results in a general method of defining hypertext structure that is both hierarchical and compositional
