We describe a technique for user interaction with the in- terim results of Formal Concept Analysis which we hypothesise will ex- pedite user comprehension of the resultant concept lattice. Given any algorithm which enumerates the concepts of a formal context, this tech- nique incrementally updates the set of formal concepts generated so far, the transitive reduction of the ordering relation between them, and the corresponding labelled Hasse diagram. User interaction with this Hasse diagram should prioritise the generation of missing concepts relevant to the user's selection. We briefly describe a prototype implementation of this technique, including the modification of a concept enumeration al- gorithm to respond to such prioritisation, and the incremental updating of both the transitive reduction and labelled Hasse diagram.
