God Classes

: Identified God Classes :::

The god classes I identified, and their corresponding number of methods can be found in Table 1{reference-type="ref" reference="tab:god_classes"}.

Note: the number of methods was computed by considering only methods and not constructors.

Feature Vectors

Table 2{reference-type="ref" reference="tab:feat_vec"} shows aggregate numbers regarding the extracted feature vectors for the god classes.

Clustering

Algorithm Configurations

Report/comment the algorithm configurations (distance function, linkage rule, etc.). You may do so in any form you feel suited, but a short paragraph of text is probably sufficient.

Testing Various K & Silhouette Scores

1 Report data about the clusters produced by the two algorithms at various k (#clusters, size of clusters, silhouette scores). You may use any suitable format (table, graph, ...).

2 Briefly comment your results. What is the best configuration, and why? Anything else you observed?

Evaluation

Ground Truth

I computed the ground truth using the command .... The generated files are checked into the repository with the names ....

Comment briefly on the strengths & weaknesses of our ground truth.

Precision and Recall

: Evaluation Summary :::

Precision and Recall, for the optimal configurations found in Section 3{reference-type="ref" reference="sec:clustering"}, are reported in Table 3{reference-type="ref" reference="tab:eval"}.

Practical Usefulness

Discuss the practical usefulness of the obtained code refactoring assistant in a realistic setting (1 paragraph).
