StackLite Dataset

David Robinson reports on a new Stack Exchange data set available to the public:

For each Stack Overflow question asked since the beginning of the site, the dataset includes:

  • Question ID
  • Creation date
  • Closed date, if applicable
  • Deletion date, if applicable
  • Score
  • Owner user ID (except for deleted questions)
  • Number of answers
  • Tags

This is ideal for performing analyses such as:

  • The increase or decrease in questions in each tag over time

  • Correlations among tags on questions

  • Which tags tend to get higher or lower scores

  • Which tags tend to be asked on weekends vs weekdays

  • Rates of question closure or deletion over time

  • The speed at which questions are closed or deleted

This is pretty exciting.  Getting good, high-quality data sets for demonstration and pedagogical purposes is time-consuming, so the fact that the Stack Exchange people are tossing one out our way could be a major time-saver.
