Abstract : Feature Models FMs are a popular formalism for modelling and reasoning about commonality and variability of a system.
In essence, FMs aim to define a set of valid combinations of features, also called configurations.
In this paper, we tackle the problem of synthesising an FM from a set of configurations.
The main challenge is that numerous candidate FMs can be extracted from the same input configurations, yet only a few of them are meaningful and maintainable.
We first characterise the different meanings of FMs and identify the key properties allowing to discriminate between them.
We then develop a generic synthesis procedure capable of restituting the intended meanings of FMs based on inferred or user-specified knowledge.
Using tool support, we show how the integration of knowledge into FM synthesis can be realized in different practical application scenarios that involve reverse engineering and maintaining FMs.
