METHOD AND APPARATUS FOR GENERATING STRUCTURED DOCUMENT

A structured document generating method and apparatus capable of easily generating a structured document matching the document structure of each non-structured document, by using a rule directly generated from a preset document structure definition for the conversion of the non-structured document into the structured document. A keyword extracting module extracts a keyword representative of the document structure from a non-structured document by using a keyword extracting rule, and a keyword/text model is generated which is described by two elements including keywords and other strings. A parsing module generated by a process of automatically parsing the document structure by referring to a parsing rule generated by modifying and converting DTD, performs a parsing process relative to the keyword/text model to generate an interim SGML document. An SGML document correcting module modifies the interim SGML document and generates a final output of an SGML document by referring to DTD different information generated when the parsing rule was generated.
