We propose a conceptually new type of bipolar queries meant as those in which a required condition, to be necessarily satisfied, and desired condition, to be satisfied if possible, are included. In the new type of bipolar queries, termed compound bipolar queries, both the required and desired conditions have been assumed to be queries with fuzzy linguistic quantifiers as introduced in the earlier works of the authors. We propose a logical formulation of the resulting compound bipolar queries for which a truth value can be calculated. The new type of a bipolar query proposed is a further step towards a higher human consistency of database queries to be employed by non-expert human users of an obvious limited command of database querying.

Compound bipolar queries: combining bipolar queries and queries with fuzzy linguistic quantifiers
