Abstract
Visualizing and understanding large conceptual schemas requires the use of
specific methods. These methods generate clustered, summarized, or focused schemas
that are easier to visualize and understand. All of these methods require computing
the importance of each entity type in the schema. In principle, the totality of knowledge
defined in the schema could be relevant for the computation of that importance
but, up to now, only a small part of that knowledge has been taken into account. In
this paper, we extend seven existing methods for computing the importance of entity
types by taking into account more relevant knowledge defined in the structural and behavioural
parts of the schema. We experimentally evaluate the original and extended
versions of these methods with three large real-world schemas. We present the two
main conclusions we have drawn from the experiments.
