In particular, we emphasize the need for taking into account background knowledge in formal concept analysis.

Such priorities serve as a constraint---only those formal concepts which are compatible with user's priorities are considered relevant, extracted from data, and presented to the user. Our approach has two main practical features. First, the number of formal concepts presented to the user may get significantly reduced. As a result, the user is supplied with relevant formal concepts only and is not overwhelmed by a large number o
