Bottom-up algorithms treat each document as a singleton cluster at the outset and then successively merge (or agglomerate) pairs of clusters until all clusters have been merged into a single cluster that contains all documents. WaveCluster. By querying the data mining schema rowset, you can find the same information that is returned in a DMX content query. The fact that you are using complete linkage vs. any other linkage, or hierarchical clustering vs. a different algorithm (e.g., k-means) isn't relevant. To perform hierarchical cluster analysis in R, the first step is to calculate the pairwise distance matrix using the function dist(). I could recommend you to read the systematic literature review first, some of them are listed here: Chapter 13 Hierarchical clustering 13.1 Introduction Hierarchical clustering extends the basic clustering task by requesting that the created clustering model is hierarchical.
