Due to the heterogeneity and distribution of explicit information, it is difficult to share the information piled in public and private sectors. In other words, the structure and format of the information that are locally defined and managed by heterogeneous data sources make information retrieval and reuse difficult. To address this issue, we design and implement a mediator/wrapper to support a quick look and easy management of the explicit information. The mediator gives a consolidate view of the information and the wrapper extracts demanded information from each data source. In addition, we provide an automated tool to facilitate the creation of a wrapper corresponding to a data source. Our experimental results show that our system gives fast and correct answers of given queries.
