[Corpora-List] portability studies?

[Taras Zagibalov]

Dear colleagues,
I've been trying to study the problem of NLP systems' portability, but 
failed to find any paper covering the subject. Could you please advise 
of any source of information that describes the problem of porting an 
NLP system to different domains/genres/languages and provides some 
metrics that measures how much it takes (of time, labour, resources...) 
to port a system.
Thank you in advance.
