Before a Wikipedia bot is allowed to edit, the operator of the bot must get approval. The Bot Approvals Group (BAG), a committee of Wikipedia bot developers, users and editors, discusses each bot request to reach consensus regarding approval or denial. We examine factors related to approval of a bot by analyzing 100 bots' project pages. The results suggest that usefulness, value-based decision making and the bot's status (e.g., automatic or manual) are related to approval. This study may contribute to understanding decision making regarding the humanautomation boundary and may lead to developing more efficient bots.
