Clustering for Generating Framework Top-Level Views

To use a framework, developers need to understand its building blocks. In this paper, we present a clustering technique that employs usage data from framework instantiations as examples to produce an overview of a framework´s main building blocks as seen from a user´s perspective. The evaluation of the approach by two case studies shows that the automatically generated building blocks are similar to a manually defined overview created by framework experts, even in cases where only few framework instantiations are available.
