: The paper evaluates how well different algorithms predict new connections (links) in a network based on the distance between nodes (hops).

The number most specifically refers to a scientific publication regarding link prediction in social networks . If you are looking for a guide on this topic, it centers on analyzing "2-hop" and "3-hop" neighborhood algorithms. Understanding Research Paper 125532
