[Corpora-List] Standard defenition for Comparable corpora

[Dekai Wu]

Hi Somayeh, on a related discussion recently I posted a pointer to 
http://www.cs.ust.hk/~dekai/library/WU_Dekai/nonparallel.html 
<http://www.cs.ust.hk/%7Edekai/library/WU_Dekai/nonparallel.html> where 
you can find an HTML table summarizing the differences between four 
different degrees of (non)parallel corpora, synthesized from some 
surveys within papers by Pascale Fung, including:

1. parallel corpus
2. noisy parallel corpus
3. comparable corpus
4. quasi-comparable (very-non-parallel) corpus
