 ## About dataset
 
-This dataset is used in our study which investigates the correlation between GitHub communication metrics and citation counts, examining the
-potential of the metrics as altmetrics.
+We construct this dataset for our study, which investigates the correlation between GitHub communication metrics and citation counts, examining the potential of the metrics as an altmetric.  
+
+Currently, it contains about 12,000 samples of publications, which are published by top-tier AI conferences. 
+The citation counts and the corresponding GitHub metrics might need to be updated. 
+We strive our best to update more conferences and keep values up-to-date.
+
+### Target conferences
+
+We collect publications from 2018 to 2022 in the following conferences:
+
+- CVPR
+- ECCV
+- ICML
+- ICLR
+- NeurIPS
+
+Those are conferences which are to be included.
+
+- ICCV
+- ACL
+- EMNLP
+- NAACL
+- AAAI
+- INTERSPEECH
+- ICASSP
 
 ## Contributors
 
+Please note that most contributors in this project major in library science, so there might be a need for more knowledge about ML/DL and AI fields.
