This repository contains the implementation of the research paper titled "Technological Taxonomies for Hypernym and Hyponym Retrieval in Patent Texts".

Paper: https://hal.science/hal-03850399

Download the CPC titles from CPC bulk data:

wget https://www.cooperativepatentclassification.org/sites/default/files/cpc/bulk/CPCTitleList202401.zip

Once you have downloaded the CPC titles list, unzip it.

Run the following command to create taxonomy trees for each domain:

python tree2pairs.py

If you want to have separate pairs of concept-hypernym for entities and descriptions of concepts, continue implementing the post-processing with the previous output directory:

python tree2pairs ./trees_CPC8-2
