The rapid growth of human computation within research and industry has produced many novel ideas aimed at organizing web users to do great things. However, the growth is not adequately supported by an overarching framework with which to understand each new system in the context of the old. We give a human computation classification system that can help identify parallels between different systems and reveal "holes" in the existing work as opportunities for new research. Since human computation is often confused with "crowdsourcing" and other terms, we explore the precise position of human computation with respect to other related topics.
