abstract = {The aim of this paper is to present new ideas on how to analyse fuzzy data using logic tools. We propose a modal logic based on fuzzy relations. Special attention is paid to similarity relations on a set of objects. We discuss its relationships to rough sets. Then, we give useful properties for transformation of formulas.},
