Abstract

We explore the usage of the modal possibility operator (andits dual necessity operator) in qualitative data analysis, andshow that it - quite literally - complements the derivationoperator of formal concept analysis; we also propose a newgeneralization of the rough set approximation operators. Asan example for the applicability of the concepts we investigatethe Morse data set which has been frequently studiedin multidimensional scaling procedures.
