Enhance hypernym detection to provide better results.
- Download prepared scripts and data:
pip install majka
cd ia161-hyperand run
- The script reads file
vstup.txt(each line is word|definition) and outputs hypernym for each word.
- Default approach is naive: first noun in definition is hypernym
- majka gives noun to some adjectives, deal with this to improve results
- Update the
hyper.pyto provide better results.
- Upload updated script plus the output.
- Gold standard to evaluate your result: gold.txt
