Installing and Running

To use build module, you will need to install Python module nltk and spacy, and then install some data from Language-specific words:

$ make develop  # or make install

The above make command uses defaults the language to English. If you would like to install for another language set the variable LANG. For example:

$ make develop LANG=fr

In order to use the Extended Open Multilingual Wordnet with NLTK and use even more languages, you need to install them manually. Go to, download the data, and then create a new folder under $HOME/nltk_data/corpora/omw/your_language where you put the file from wiki/, and rename it to

If you get the message

OSError: [E050] Can't find model 'en'. It doesn't seem to be a shortcut link, a Python package or a valid path to a data directory.

There is a problem with the spacy the library for advanced Natural Language Processing in Python.

You might be able to fix this running:

python -m spacy download en

Adjust “python” and “en” (the language you want) above as needed.
