Is there any established xml or other markup language for novels and 
short stories?
I'm particularly interested in marking up dialogue with the name of the 
character who is speaking, and then in tools that allow extracting the 
dialogue of each character (e.g. to analyse and contrast the vocabulary 
each uses).
If so, following on from that, are there open-source ML models that try 
to identify the speaker to add this markup, and existing training data?
Thanks,
Darren
