Abstract: The rise of open innovation has changed the company’s management practice concerning productdevelopment and problem-solving. As a result, companies have started seeking ways to incorporate external ideas into
internal innovations using crowdsourcing. However, idea generation itself yet depends largely on personal abilities.
Therefore, ideas are rarely substantially changed through collaboration or combination in common web-basedarchitectures. Idea generation support via information system is expected to provide a new approach toward idea
evolution. In this study, we propose an information system that dynamically recommends personalized information tofacilitate each user’s idea generation. And, we implement our methods on our idea posting site to evaluate its
effectiveness on the quality of posted ideas by using crowdsourcing. Specifically, this study proposes and verifies twomethods for facilitating idea generation: presenting site visitors top three ideas with high evaluations to promote idea
combinations and presenting questions to encourage site visitors to think deeper into ideas.
