Added ski-violations.txt: a mapping of sense key violations, i. e. a small number of accidental cases, where a sense key changed meaning during a WordNet update.
Corrected the version name of the WordNet 1.5SC release from October 1995. This was the first fully "coherent" version, with only unique sense keys.
WordNet 1.5 now refers to the release from March 1995, instead of the later WN 1.5SC, since it is the version used by other projects (Sensemap, UPC, ILI). Please note that a few sense keys from WN 1.5 were not unique, as almost 40 were in more than one synset.
Added WordNet 3.1.1 for SQL (2012), retrieved from http://wordnetcode.princeton.edu/wn_for_sql.tar.gz.
Removed adjective markers (a,p,ip), which were present in WordNet 1.5 and 1.6 sense keys.
Set LC_ALL=C in the subshell for each script, to ensure consistent sort order across platforms.
Dropped conversion to lowercase for MCR lemmas, because MCR wordsense numbers depend on the case.
