Možnosti ověření kvality otevřených dat

This bachelor’s thesis addresses the issue of verifying the quality of open data. The main objective of the thesis is to evaluate the quality of selected open datasets through technical checks and to subsequently analyze the identified shortcomings. The thesis first defines basic concepts and dimensions of data quality, and then analyzes procedures and rules for ensuring data quality in the Czech Republic and in selected foreign countries (France, Ireland, and Spain). Subsequently, five measurable metrics covering selected dimensions of data quality are proposed, which are applied to three datasets from the National Open Data Catalog using SQL scripts. The results of the analysis revealed significant inconsistencies in data quality, particularly error rates in the IČO identifier. Based on these findings, the conclusion of the thesis formulates specific recommendations aimed at improving the quality of published open data.
