To celebrate the openESM paper release, I wrote a brief blog post summarizing recent developments: openesmdata.org/blog/2026-07... We: 💠added more data 💠provided descriptive visualizations for each item 💠created a semantic similarity mapping for items, making it easier to find related items

openesmdata.org

Updates: Paper published, new dataset & features

Our tutorial paper on openESM has been published, and we have added new datasets and features to the platform.

Perspective: Open-ended responses can improve ESM data by grounding it in real-world experiences and phenomena as they are experienced in everyday life. Handbooks and guidelines on ESM should include sections on collecting and analyzing open-ended text items. www.nature.com/articles/s44...
