Searching for analogical ideas with crowds

Seeking solutions from one domain to solve problems in another is an effective process of innovation. This process of analogy searching is difficult for both humans and machines. In this paper, we present a novel approach for re-presenting a problem in terms of its abstract structure, and then allowing people to use this structural representation to find analogies. We propose a crowdsourcing process that helps people navigate a large dataset to find analogies. Through two experiments, we show the benefits of using abstract structural representations to search for ideas that are analogous to a source problem, and that these analogies result in better solutions than alternative approaches. This work provides a useful method for finding analogies, and can streamline innovation for both novices and professional designers.
