Hierarchical Clustering
Typical cluster hierarchy (or dendogram)
- Start with a set of singleton clusters, each contains
one object (document)
- Repeat the following steps iteratively until there is
only one cluster
- Identify the two clusters that are the most similar
- Merge them together into a single cluster
Requires measure of similarity between documents' profiles
