碩士 === 中原大學 === 資訊工程研究所 === 96 === XML is becoming the standard for data exchanges and data representation. Keyword search allows a user to easily query and access XML data and thus becomes an important research issue. In this thesis, we used Dewey-base two indices to index XML data. It does not require re-computation of existing labels when an XML document is updated. When returning keyword search results, we use the relationships between nodes ensure the return data is correct and to avoid returning meaningless data. Users can query XML data without having to understand the XML structure. An example system was implemented as an illustration.
