The task will proceed using Python notebook run in web browser in the Google Colaboratory environment with the MU G-Suite disk access.
In case of running the codes in a local environment, the requirements are Python 3, and NLTK module.
- Access the Python notebook in the Google Colab environment and make your own copy. Do not forget to save your work if you want to see your changes later, leaving the browser will throw away all changes!
- The script reads file
input.txt(each line is word|definition) and outputs hypernym for each word.
- Default approach is naive: first noun in definition is hypernym
- Update the
find_hyper()function to provide better results.
- Upload updated script plus the output.
