Differences between XWN 1.7 and XWN 2.0-1

The main difference between these two releases is that XWN 1.7 is based on WordNet 1.7, while XWN 2.0-1 is based on WordNet 2.0

The second difference is given by the new format in which XWN 2.0-1 is presented:
In XWN 1.7, for each part of speech there were three files: one for word sense disambiguation, one for parse trees and another one for logic form transformations.
In XWN 2.0-1, these three files have been collapsed into a single file containing all the information.
Moreover, the files are aligned at synset level (i.e. to each synset we attached the WSD, parse trees and LFTs of its gloss, in an XML format).
