Formal Concept Analysis (FCA) is a method that allows to identify concepts and their interrelationships in a well understood and formally sound way. Based on that, so called Iceberg Concept Lattices, introduced in the early 2000s, represent conceptual knowledge that is best supported in the data given a certain minimum support threshold. This allows for limiting the level of detail of the knowledge encoded within a concept lattice. The talk will provide a brief introduction into the fundamentals of FCA, showcase what Iceberg Concept Lattices are and how they are being computed. The talk will then close with an outlook into the exploitation of this technique for Semantic Web applications, e.g. within the Koldfish project.
