+This dataset consists of three CSV files, namely: 'cs.csv', 'ds.csv', and 'p.csv'. 
+Each CSV file includes the data for the questions asked on a Stack Exchange (SE) question-answering community, from the creation of the community until May 2021.
+
+- 'cs.csv' --> [Computer Science SE](https://cs.stackexchange.com/)
+- 'ds.csv' --> [Data Science SE](https://datascience.stackexchange.com/)
+- 'p.csv' --> [Political Science SE](https://politics.stackexchange.com/)
+
+Each CSV file has the following columns:
+
+- `id`: the question id
+- `title`: the title of the question
+- `body`: the body or text of the question
+- `tags`: the list of tags assigned to the question
+- `label`: a label indicating whether the question is resolved or not (0: not resolved; 1: resolved)
+
+The dataset was used in these researches:
+
+- [A deep learning-based approach for identifying unresolved questions on Stack Exchange Q&A communities through graph-based communication modelling](https://doi.org/10.1007/s41060-023-00454-0)
+- [Survival analysis for user disengagement prediction: question-and-answering communities’ case](https://doi.org/10.1007/s13278-022-00914-8)
