When you're following instructions, you may want to see more detailed instructions about a step. In the terms of natural language processing, this reflects the hierarchical relationship among procedural events, where each step can have many sub-steps.

This web demo accompanies our ACL 2022 paper and lets you explore the procedural hierarchy discovered from wikiHow. You can start with a random procedure by clicking "I'm feeling lucky" or go for a particular one using the search bar. You can expand upon the steps when available to see more detailed instructions, which are predicted by our models with a confidence score.
