I'm looking to use a tree kernel (e.g. Zelenko et al., 2003, Moschitti 2006, etc.) for text classification in Python. However, I'm still a little unclear on the implementation. Is there an existing implementation (in any language) that I could use as a reference, or is there a 3rd-party tree kernel library I could use?
