cltl / opendutchwordnet Goto Github PK

I would like to see a proper install script (i.e. a setup.py) so that I can use the wordnet in my own programs without having to explicitly copy the sources somewhere. Is there a reason this wasn't done for this project?

Some words yield more than 8000 synonyms. Try:

from OpenDutchWordnet import Wn_grid_parser
instance = Wn_grid_parser(Wn_grid_parser.odwn)
syns = instance.les_lemma_synonyms('generiek')
print(len(syns), list(syns)[:20], '...')
8812 ['wildkamperen', 'indiscretie', 'inbegrip', 'Noordzee', 'borstwijdte', 'Turkmeense', 'Moskou', 'onvruchtbaarheid', 'augurk', 'expresweg', 'saloondeuren', 'oud-minister', 'raclette', 'samenpakken', 'Armenië', 'werkloosheidsprobleem', 'Zevengebergte', 'luchtledige', 'spellingwijziging', 'treinstaking'] ...
syns = instance.les_lemma_synonyms('kalender')
print(len(syns), list(syns)[:20], '...')
8817 ['wildkamperen', 'indiscretie', 'inbegrip', 'Noordzee', 'borstwijdte', 'Turkmeense', 'Moskou', 'onvruchtbaarheid', 'augurk', 'expresweg', 'saloondeuren', 'oud-minister', 'raclette', 'samenpakken', 'Armenië', 'werkloosheidsprobleem', 'Zevengebergte', 'luchtledige', 'spellingwijziging', 'treinstaking'] ...
syns = instance.les_lemma_synonyms('post')
print(len(syns), list(syns)[:20], '...')
8834 ['wildkamperen', 'indiscretie', 'inbegrip', 'Noordzee', 'borstwijdte', 'Turkmeense', 'Moskou', 'onvruchtbaarheid', 'augurk', 'expresweg', 'saloondeuren', 'oud-minister', 'raclette', 'samenpakken', 'Armenië', 'werkloosheidsprobleem', 'Zevengebergte', 'luchtledige', 'spellingwijziging', 'treinstaking'] ...

Most words work fine (in al list of 90 words, 10 yield the 8000+, the others not, without any apparent logic). The xml entries in odwn_orbn_gwg-LMF_1.3.xml.gz look fine (to me) too. Is this a bug in les_lemma_synonyms?

Using the Wordnet for English you can look for a word, e.g., car and it will tell you that it is a noun. Is there a similar function in this module?

It would be handy if the database was provided in the same format as other wordnet databases. If this were the case, already existing interfaces, such as the wordnet-cli/wn interfaces provided by the Princeton WordNet project, could be use together with this Dutch database. This will be really beneficial for the scripting community at large; e.g. to my knowledge, there is no good offline dutch traditional dictionary database (except maybe this one) but it's quite hard to properly integrate the Dutch database as it exists now into existing dictionary lookup programs. Same for other purposes you might think of. As it stands now, the current database---at a glance at least---seems kinda scattered and to be made out of different kind of files in different formats.

For example, the Princeton wordnet program contains a directory structure like this (and theoretically already allows you to use different "dictionaries"):

...
/usr/share/wordnet/dict/adj.exc
/usr/share/wordnet/dict/adv.exc
/usr/share/wordnet/dict/cntlist
/usr/share/wordnet/dict/data.adj
/usr/share/wordnet/dict/data.adv
/usr/share/wordnet/dict/data.noun
/usr/share/wordnet/dict/data.verb
/usr/share/wordnet/dict/noun.exc
...

Currently, the directory structure of the project is set up in such a way that I have to explicitly do cd .. to use the examples in the README.MD file. This could be solved by moving the sources to another directory (typically the name of the project, i.e. opendutchwordnet for this project). This would also solve the docs and the sources being jumbled together.

Compare:

>>> x = instance.synsets_get_generator()
>>> s = next(x)
>>> s.get_pos()
'n'

With:

>>> le_el = instance.les_find_le("havenplaats-n-1")
>>> le_el.get_pos()
'noun'

I tried installing OpenDutchWordnet, using the install.sh (or actually create_virtual_env.sh). The script succeeds, but if I run the example code, >>> from OpenDutchWordnet import Wn_grid_parser I get ImportError: No module named 'OpenDutchWordnet'.

If I look at the script, it seems no module is installed, it just creates a virtualenv and installs lxml from requirements.txt. Also, there is no setup.py.

What am I missing?

Hi,

I am not able to find hypernyms of a certain lemma.
With Wordnet, it's possible to do
dog = wn.synset('dog.n.01') dog.hypernyms()
Resulting in:
[Synset('canine.n.02'), Synset('domestic_animal.n.01')]

Is there a similar method for the Dutch Wordnet?

Thank you in advance!
