Figure 2.  Single-link:  minimum similarity



complete-link: minimum similarity


 centroid: average inter-similarity


         Group-average: average of all similarities





A single-link (left) and complete-link (right) clustering of eight documents. The ellipses correspond to successive clustering stages. Left: The single-link similarity of the two upper two-point clusters is the similarity of d2 and d3 (solid line), which is greater than the single-link similarity of the two left two-point clusters (dashed line). Right: The complete-link similarity of the two upper two-point clusters is the similarity of d1 and d4 (dashed line), which is smaller than the complete-link similarity of the two left two-point clusters (solid line).
