Stack Exchange Open Source site questions categorization

This dataset contains the posts of Open Source Stack Exchange site, collected at the end of 2020, along with the categorization of the posts. For each post a category, and potentially a second one is indicated, along with the cluster (generic group) each category belongs to. The coding task of assigning each question to a category was performed by two independent coders for each question (the categorization of each coder is also provided in the dataset).
