Workshop Themes: [Chance Discovery: Synthesis and Curation of Chance]

Since our definition in 2000, Chance Discovery is the discovery of chance, rather than discovery by chance. A ``chance" here means a new event/situation that can be conceived either as an opportunity or as a risk in the future. The ``discovery" of chances is of crucial importance since it may have a significant impact on human decision making. Desirable effects of opportunities should be actively promoted, whereas preventive measures should be taken in the case of discovered risks. In other words, chance discovery aims to provide means for inventing or surviving the future, rather than simply predicting the future.
This workshop will discuss several problems in Chance Discovery. As shown, Chance Discovery is a research to study how to discover rare or novel events causing potentially significant situation. Although the event itself could not be significant. A chance might be computationally or manually discovered. Thus, advanced computational techniques such as abduction and induction (including data mining) could be applied to Chance Discovery. In addition, personalised and very traditional (sometimes, manual) data mining method could also be effective in Chance Discovery. We have discussed limitations of conventional data mining methods. And many new computational methods, and concepts and mechanisms of human discovery have been proposed. In the contexts, we have discussed how to discover and suggest events causing significant but hidden events. Our common understandings are that we deal with events in the real world, therefore, we need to have knowledge about movement in a society, behaviour of people, as well as computational methods. In addition, it is important to discuss effective chance evaluation, selection, and suggestion methods. It would be a gate for fantastic and innovative applications. Thus, we would like to discuss from logical, computational, cognitive, sociological, economical and psychological viewpoints. In addition, we would like to discuss ``curation'' of chance. Traditionally, curation is not only concerned with long-term care of books, paintings or other artefacts. It is also about maintaining their integrity and enabling and promoting their availability to appropriate audiences (, i.e., an aspect for information synthesis. As shown above, for chance discovery, we have focused on strategies to discover rare or novel events and those to present hints of chance to users. In addition, by curation, we add a more active action to chance discovery, which, for instance, curators usually struggle to explicitly or implicitly express extended or hidden meanings (values) to potential audiences.
By introducing these new concepts---chance synthesis and curation, we can go beyond what we called chance discovery--- reach creating and re-organization of chances, not in our previous application fields such as product designs/marketing but also the design of peaceful and prosperous society to live in.
In addition, this year, we would like to discuss 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 also 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. This can be regarded as a new type chance synthesis.

Topics to be discussed (will not be restricted to):

Actually, we are waiting for new research fields or proposals (not included in the above list) which might be related to or contribute to chance discovery, curation and data market.

Important date:


Paper submissions should be limited to a maximum of 6 pages in the ECAI2014 conferene paper format.
Papers can be submitted to Akinori Abe ( and Yukio Ohsawa(


All submissions will be reviewed on the basis of relevance, novelty, originality, significance, soundness and clarity. At least three referees will review each submission independently.


Accepted papers will be uploaded on this web site. ECAI-2014 will not issue workshop proceedings... After the workshop, we would like to organize a special issue in a certain journal including revised and extended version of selected workshop papers (see below....).

Special information:

After the workshop, we would like to organize a special issue in a certain journal including revised and extended version of selected workshop papers. Authors of submitted papers are advised to extend for our special issues about the paper's relevant topics, from journals e.g., Intelligent Decision Technologies.
