Formal Concept Analysis (FCA) derives a multiple-inheritance class hierarchy from a formal context. The number of classes is bounded above by an exponential function of the number of objects and attributes in the context. To support interactive analysis of large formal contexts, this paper exploits a divide-and-conquer technique which discovers hierarchical structure in amenable formal contexts. That hierarchical structure is used to expedite and enhance both the layout of, and user interaction with, the concept lattice. The principal contribution is the dual use of the discovered hierarchical structure for scalable, interactive FCA.
