Implementation of Universal DTD Generator based on Ontology

온톨로지 기반 보편적 DTD생성기의 구현

XML is widely used to provide information on the web. Since accessing XML documents depends on their structures, it is difficult to extract necessary information from documents having different structures. We constructed an ontology of a small application domain and implemented an universal DTD generator from the ontology. The universal DTD can be used in extracting necessary information from the various XML document types representing an identical idea.
