#4 Update for version 2.1 of WordNet

[Martin Thorsen Ranang]

WordNet 2.1 introduces the distinction between hyponyms
that are instances and hyponyms that are classes.
Earlier all hyponym relations were tagged with a '@' in
the WordNet database/lexicographer files. Now,
however, an "instance of" relation is signified with a
'@i' tag. This required an update of the wordnet.py
script. A small patch should be attached.

[Martin Thorsen Ranang]

Patch to support WordNet 2.1 with "instance of" relations.

I also noted someone had trouble with the missing lexnames
file, so I believe have generated a (hopefully correct) new
one, according to lexnames(5) (the man page). I will attach
that file too. Just save it in the $WNHOME/dict directory
and rename it to "lexnames".

I just discovered a problem with the patch I submittet. It
does not handle hyponyms correctly. Therefore, I attach a
new patch with this posting that is supposed to be applied
after the first patch. I'm sorry for any inconvenience this
may have caused.

[Martin Thorsen Ranang]

A patch to correct the first patch (wordnet-2.1-update.diff).

After applying those patches on Windows, I still get the error:

(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more

For Windows, you have to replace all "C:\\Program
Files\\WordNet\\2.0" with "C:\\Program Files\\WordNet\\2.1"
in wordnet.py

I still get the following exceptions when I import wordnet,
but afterwards I'm able successfully access Wordnet.
Exception exceptions.AttributeError: "DbfilenameShelf

After applying those patches, it seems to import correctly,
but I get the following error/warnings on import:

Exception exceptions.AttributeError: "DbfilenameShelf
instance has no attribute 'writeback'" in ignored

I'm on Linux, FC5.
