The "hierarchical clustering" may be referred to by some as "chunking",
making large, complex bodies of information more easily accessable for use
(LL's take on it). This is fascination reading;
downloadable documents for your toolbox.

Many empirical studies about knowledge examine *how much* people know about
various content domains, from physics and history to movies and chess. Our
research examines the *structure* of such knowledge. For example, is the
information loosely structured based on weak associations, or is it
structured in a systematic, hierarchical way? To study knowledge
structures, we use a variety of empirical and quantitative methods (such as
hierarchical clustering). Experiments examine: --what knowledge
structures are
--how to measure them
--how they vary across content domains
--how they vary with degrees of expertise
--how to foster their development
