Chromium Conversations

A Dataset for Identifying Actionable Feedback in Collaborative Software Development

Datasets

chromium_conversations.csv

This is the full dataset containing over 1.5 million comments posted by developers reviewing proposed code changes. The dataset also includes the values we calculated for all nine linguistic features (described in Section 4 of the paper cited below).

chromium_conversations_annotations.csv

This dataset is a subset of the chromium_conversations.csv dataset. It contains the data used in the classification experiment outlined in Section 5 of the paper cited below (2,994 comments automatically identified as acted-upon and 800 comments manually identified as not (known-to-be) acted-upon).
