Webcalculated. Then, this algorithm selects two adjacent clusters based on the distance, and merges these two clusters into a new cluster. After that, the distances between clusters are recalculated. The Walktrap algorithm has several advantages like it can be computed efficiently and it captures many characteristics on the structure of clusters. 2 WebThe only distinguishing feature is the representation of each community family depending on the community detection method. Edge Betweenness proposes the most balanced clusters (Table 4), while Louvain produces mainly Family 1 and 2 items, and not surprisingly, most of the 167 (small) communities produced by Walktrap are from Family 3.
