I will discuss the following paper, which introduces an infinite hierarchy of Chinese restaurant processes to model sequence data:

Wood, Archambeau, Gasthaus, James, Teh, “A Stochastic Memoizer for Sequence Data”. www.gatsby.ucl.ac.uk/_{ywteh/research/compling/WooArcGas2009a.pdf}

As background reading: the hierarchical Pitman-Yor process was introduced in Teh, “A Hierarchical Bayesian Language Model based on Pitman-Yor Processes” http://www.gatsby.ucl.ac.uk/ywteh/research/compling/acl2006.pdf
