This paper describes a method for inferring when a person might be coordinating with others based on their behavior. We show that, in Wikipedia, editing behavior is more random when coordinating with others. We analyzed this using both entropy and conditional entropy. These algorithms rely only on timestamped events associated with entities, making them broadly applicable to other domains. In this paper, we will discuss previous research on this topic, how we adapted that research to the problem ofWikipedia edit behavior, describe how we extended it, and discuss our results.
