Description
Book SynopsisThis volume constitutes the papers of several workshops which were held in conjunction with the 27th International Conference on Database Systems for Advanced Applications, DASFAA 2022, held as virtual event in April 2022.
The 30 revised full papers presented in this book were carefully reviewed and selected from 65 submissions.
DASFAA 2022 presents the following five workshops:
· First workshop on Pattern mining and Machine learning in Big complex Databases (PMBD 2021)
· 6th International Workshop on Graph Data Management and Analysis (GDMA 2022)
· First International Workshop on Blockchain Technologies (IWBT2022)
· 8th International Workshop on Big Data Management and Service (BDMS 2022)
· First workshop on Managing Air Quality Through Data Science
· 7th International Workshop on Big Data Quality Management (BDQM 2022).
