The paper presents theorems characterizing concept lattices which
happen to be trees after removing the bottom element. Concept lattices
are the clustering/classification systems provided as an output of
formal concept analysis. In general, a concept lattice may contain
overlapping clusters and need not be a tree. On the other hand, tree-
like classification schemes are appealing and are produced by several
classification methods as the output. This paper attempts to help
establish a bridge between concept lattices and tree-based
classification methods. We present results presenting conditions for
input data which are sufficient and necessary for the output concept
lattice to form a tree after one removes its bottom element. In
addition, we present illustrative examples and several remarks on
related efforts and future research topics. 1
