Installing and Running

To build this Mathics3 module, you will need to install the Python module nltk and spacy, and then install some data from Language-specific words:

$ make develop  # or make install

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

$ make develop LANG=fr

To use the Extended Open Multilingual Wordnet with NLTK and use even more languages, you need to install them manually. Go to http://compling.hss.ntu.edu.sg/omw/summx.html, download the data, and then create a new folder under $HOME/nltk_data/corpora/omw/your_language where you put the file from wiki/wn-wikt-your_language.tab, and rename it to wn-data-your_language.tab.

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 library for advanced Natural Language Processing in Python.

You might be able to fix this by running:

python -m spacy download en

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