Abstract :
The Purpose of this study was to generate structural documents to improve search performance of an information search system by using a thesaurus, a related-information b/t words for the information search, and to study a search technique for searching structural documents. In order to accomplish these purpose, we proposed using the DODI(Depth-Oriented Decomposition Index) technique. This index technique, using a thesaurus, was able to search related information through a search algorithm, and was therefore able to efficiently search for information. In addition, we established a structural save system to save the structural document generated by this index technique, in a database through OpenXML, and to generate an XML reformatted document, by using ForXML method. Index techniques to use thesaurus can use effectively to study is abbreviated word in studying of medical terminologies, original word, Chinese character borrowed word, purity Hangul terminology, actuality pronunciation hearing, anatomy that use by this research.
