Session
This talk introduces a novel tool that tests the data quality of a given dataset from the Open Data Hub. Besides formal tests of the data fields, the tool uses a machine learning approach to test the quality of images and whether the content of an image agrees with its description. Hence the tool can provide valuable insights into potential errors or issues with the data and images.
