Bipolar queries consist of negative and positive conditions specifying the features that are making data sought, respectively, rejected and accepted. A possible strategy to evaluate such bipolar queries is to combine matching degrees of both conditions using the and possibly operator. We studied this type of aggregation in our earlier work and afterwards proposed the concept of contextual bipolar queries which are based on a context-dependent version of the and possibly operator. Here we propose a further extension of this concept which is based on the or if impossible operator. We show some properties and possible interpretations of the proposed approach.
