WebClustering algorithms principally fall into one of two categories: either hierarchical or partitional, which differ primarily in the way in which clusters are determined (Reynolds et al., 2006). In particular, hierarchical methods organize data into a hierarchical tree of nested clusters using either an agglomerative or divisive scheme ( Reynolds et al., 2006 ).
