Figure 2: Hot topics among 1915 dental articles cited in Wikipedia. Red–yellow–green–blue color scheme was used; red corresponds to the highest keyword co-occurrence in density, and blue corresponds to the lowest density. The distance-based approach was used to create this map, which means the smaller the distance between two terms, the higher their relatedness
