Abstract
The Qualitative Choice Logic (QCL) is devoted to a logic expressing preferences for Boolean alternatives. This paper puts the first foundations to extend QCL to fuzzy alternatives. In particular, some relationships between QCL and the bipolar expression of preferences queries are emphazised. A new type of bipolar conditions is defined in the Boolean context to express QCL statements. This new type of bipolar conditions is extended to graduality and it is shown that this extension can be the basis to define a gradual QCL model.
