This presentation is a supplementary material for the "Combining Data Lake and Data Wrangling for Ensuring Data Quality in CRIS" presented at 15th International Conference on Current Research Information Systems (CRIS2022) - Linking Research Information across data spaces. It provides an insight on the ongoing study of combining data lake as a data repository and data wrangling seeking for an increased data quality in CRIS systems, although the proposed approach is domain-agnostic and can be used not only within CRIS.
