This workshop is not about data mining for marketing, but about how to create and design the market where data are reasonably dealt with, i.e., sold, opened free, or shared after negotiation. Our ultimate goal is to have each people on the earth feel free to share one's own data with others without fearing of the loss of business opportunities. In order to make a social environment where analysts and decision makers in active businesses and sciences can be provided with data they need, in this workshop we aim to (re)design an environment called the Market of Data, where each user or provider of data can understand the value of each part of data so that one can buy/sell it for a reasonable price. Here, the value of each part of data shall be visualized to aid users' considering its possible contribution to promoting/creating businesses and scientific findings. Furthermore, it is noteworthy that data scientists need to import techniques from others, but the techniques are not easy to learn from experts dealing with different kinds of data, because the similarity between data is not always obvious. The similarity between latent dynamics behind data is also desired to be represented in such a way as visualizing distances among structural features of data for aiding the choice of success/failure cases of data mining to learn from.
