The method proposed in Chan (2006) also learns within a hierarchical structure where Latent Dirichlet Allocation (LDA) is used to find stem-suffix matrices.
, w n = s n + m n }, initial tree T , initial temperature of the system γ, the target temperature of the system κ, temperature decrement η 2: initialise: Remove the leaf node D i that has the word w Draw a split point for the word such that Draw a sibling node D j 7: if p next (D|T ) >= p cur (D|T ) then 10: Accept the new tree structure 11:  γ ← γ − η 24: end while 25: output: A tree structure where each node corresponds to a paradigm.
