The Creativity Quotient (CQ) is a novel metric building on ideational fluency that accounts for both the number of novel ideas (ideation) and the number of distinct categories (fluency) these ideas fall into. Categories are, however, difficult to define unambiguously and objectively. We propose that the principal contribution of this article is an entirely algorithmic approach based on concept networks, and an information metric defined thereon. It requires only measures of the similarity between concepts, which may come from databases such as Wordnet, Wikipedia, Google, or corpus analysis tools. In the special case of strong, unique categories it reduces directly to CQ.
