Created by digital humanities and art history scholar Alkim Almila Akdag Salah, computer scientist Cheng Gao, complex networks researcher and sociophysicist, Krzysztof Suchecki, and physicist and information scientist Andrea Scharnhorst, this map shows the differences between the category structure of Wikipedia and the Universal Decimal Classification (UDC) system. Shown on the left is the main tree structure of Wikipedia categories (top four levels). Given on the right is the UDC structure as a tree (all nine levels) of this widely used library classification system. The donut chart and bar chart in the middle show the alignment of the nine UDC main classes to the 43 main topic categories used by Wikipedia. All four visualizations use the same color-coding, making it possible to explore the dominance, distribution, and interrelations of topics. The work aims to increase our understanding of how knowledge maps differ when they are created socially (Wikipedia) as opposed to when they are created formally (UDC) using classification theory.
