In the worldwide trend of big data and AI, the use of secondary data is an essential social demand in terms of cross-discipline data exchange and utilization. However, the intentions or the contexts of data collected by others tend to be unclear, which may cause difficulties in grasping facts for decision making. To avoid this contextual gap between users and collectors, we propose the retrieval system of data reflecting the collectors' contexts as well as users' requirements for making a beneficial decision. Our motivation is to support users to retrieve data without extensive knowledge of them and to improve the transparency of the retrieval process. To achieve these aims, we conducted several workshops to collect integrated knowledge of data utilization and implemented an interface for users to retrieve information about data related to their interests from free text queries.
