Abstract Creativity protocols and methodologies tend to be time consuming if applied manually. This paper presents how information technologies can support innovation and creativity for collaborative scenario creation and discussion. The fusion of change discovery, genetics algorithms, and computer-supported collaborative tools provide computational models of innovation and creativity. The proposed technology allows groups of participants in a creative processes to have pervasive access to the analysis of the current scenario in real time. This paper introduces such innovation technologies gathered in the DISCUS project, and summarizes initial successful usages of DISCUS on marketing research workshops. ...

Terms such as cybercollaboratories are getting traction in day-to-day work. Web boards, blogs, e-mails, and instant messaging have become de facto mainstream communication channels. People scattered across the globe collaborate thanks to such technologies to carry out their daily work. Creative processes—such as collaborative engineering—have also taken advantage of such new communication media. This paper reviews the new framework set after these technologies and presents how collaborative creativity and innovation can be modeled and supported using computational models. The paper continues presenting a innovation-support model based on the usage of genetic algorithms as computational metaphors of human innovation. The paper also briefly discuses the results achieved using the proposed technologies in real-world collaborative creative processes. ...

Recently I attended a talk by David Blei about probabilistic models of text and images. His thesis described probabilistic models for the retrieval, organization, and exploration of large information collections, casting this tasks as statistical queries. The abstract of his thesis ca be found here and the thesis itself here.
