Résumé
Formal Concept Analysis (FCA) is a theoretical framework which structures a set of objects described by properties. In order to migrate software product variants which are considered similar into a product line, it is essential to identify the common and the optional fea- tures between the software product variants. In this paper, we present an approach for feature location in a collection of software product variants based on FCA. In order to validate our approach we applied it on a case study based on ArgoUML. The results of this evaluation showed that all of the features were identified.
