| Research Abstract |
Our research objective is to develop a database virtualization technique and data mining agent for data analysts or other data mining users to reduce their workloads such as data collection from databases and data cleansing works. We developed schema and query conversion function for heterogeneous data models (RDB、XMLDB) using a single XML schema as user's view and confirmed the efficiency for data acquisition function. We designed and prototyped mechanism to automatically select and combine databases to achieve data mining activity and we developed an efficient content access method based on the grouping technique of the contents using the content access history and frequency.
