“…Intrinsically, the discovered links can be directly used to complete missing step-goal hyperlinks in wikiHow, which have been manually curated (B5). Our proposed method outperforms strong baselines (e.g., Lagos et al (2017)) according to both automatic and human evaluation, in terms of recall and usefulness respectively ( §4, §5). Extrinsically, we consider the task of retrieving instructional videos given textual queries.…”

“…Linking Procedural Events To the best of our knowledge, two other pieces of work Pareti et al (2014); Lagos et al (2017) tackled the task of linking steps in procedures to other procedures. Both of them also drew the procedures from wik-iHow.…”

“…More attention has been paid in fields adjacent to NLP. For example, Lagos et al (2017) and Pareti et al (2014) both create hierarchical structures in how-to documents by linking action phrases in one procedure to another procedure or by linking steps in howto articles to resources like DBPedia (Auer et al, 2007). This kind of linking is helpful for explaining complex steps to readers who do not have prior knowledge of the topic being explained.…”

Procedures are inherently hierarchical. To make videos, one may need to purchase a camera, which in turn may require one to set a budget. While such hierarchical knowledge is critical for reasoning about complex procedures, most existing work has treated procedures as shallow structures without modeling the parent-child relation. In this work, we attempt to construct an open-domain hierarchical knowledge-base (KB) of procedures based on wikiHow, a website containing more than 110k instructional articles, each documenting the steps to carry out a complex procedure. To this end, we develop a simple and efficient method that links steps (e.g., purchase a camera) in an article to other articles with similar goals (e.g., how to choose a camera), recursively constructing the KB. Our method significantly outperforms several strong baselines according to automatic evaluation, human judgment, and application to downstream tasks such as instructional video retrieval. 1 * Equal contribution. 1 A demo with partial data can be found at https://wikihow-hierarchy.github.io/.
