Web-based Innovators Marketplace on Data Jackets as Communication Support System

The importance of creating new business and making a decision by combining data in various domains has been increasing these days. Innovators Marketplace on Data Jackets (IMDJ) is a workshop method to encourage and support stakeholders’ data exchange by creating scenarios for data utilization. Data Jacket (DJ) is a framework for describing the structured information about data in natural language. The idea underlying the DJ is to share "a summary of data" as metadata without sharing the data itself, which enables stakeholders in terms of data utilization to discuss the combinations of data. However, IMDJ workshops have usually been conducted manually by using large sheets of paper with a visualized network of DJs for discussing the combinations of data, and it takes a lot of time and effort to organize the workshop. It is the problem for the market of data because it may disturb active transaction and exchange of data in different domains. In this paper, we propose the support system and extend IMDJ workshops using the Web application. Our system does not only support workshop organizers to create a visualized network of DJs automatically from the database of knowledge for data utilization, but also can acquire the logs of participants’ behaviors, which may be helpful for understanding the cognitive process of data utilization.
