Import WordNet v3.0 into KGTK format. Currently, four relations are included: hypernymy, membership holonymy, part-of holonymy, and substance meronymy. The resulting KGTK file consists of 9 columns.


usage: kgtk import-wordnet [-h] [-o OUTPUT_FILE]

optional arguments:
  -h, --help            show this help message and exit
  -o OUTPUT_FILE, --output-file OUTPUT_FILE
                        The KGTK output file. (May be omitted or '-' for


Importing WordNet can be done as follows (no inputs should be provided, as WordNet is read through the NLTK package):

kgtk import-wordnet -o wordnet.tsv
