Companies often develop in a non-disciplined manner a set of software variants that share some features and di er in others to meet variant-specific requirements. To exploit existing software variants and manage them coherently as a software product line, a feature model must be built as a first step.

In this book, we propose an automatic approach to organize the mined documented features into a feature model. The feature model...
