This report shows how lattice theory can be used to develop quantitative measures of selected characteristics of knowledge structure representations and how these measures can be used to assess individual person's knowledge structure representations in a classroom setting. For a given set of concepts, a knowledge structure can be described by the…

Demonstrates that if the similarity function of a retrieval system leads to a (pseudo-) metric, the retrieval, similarity and Everett-Cater metric topology coincide and are different from the discrete topology; this is the case if documents are represented by lists, using the Jaccard similarity measure. The corresponding metric is the…
