Currently doing background research and collecting my notes for the DH 2010 submission on similarity metrics and the Courval texts. I've written a couple of paragraphs on the background, and started compiling a bibliography. Lots of work still to do. Also investigating the possibility that we might be able to use XPath in the Delphi demo app, with some success (helped by the ADOM author DK); but there are some limitations that might make it a bit complicated for a general-purpose tool. I'll have to think about it a bit more.
