Hierarchical clustering of e-resources using the shared descriptors similarity matrix (method 2). (A) The scores based on binary weights. (B) The scores based on tf*idf. Distances were calculated as (1 – Sim2). Ward’s minimum variance clustering method [21] was used to cluster the data. The tree was generated using R function ‘hclust’ [20].
