The Data Quality Assessment Technique of Personal Data Operators Register

Abstract

The work considers the issue of completeness and accuracy of personal data operators register published by Federal Service for Supervision in the Sphere of Telecom, Information Technologies and Mass Communications. The set of tools was designed and the data quality assessment technique was determined. The suggested technique was implemented via the information and analytical system including ETL module, metadata repository and check execution module. An experimental test of the implemented system covered a random sample of 1671 currently active operators. The resulting data quality assessment highlighted inaccuracies in records of 12% operators, including data incompleteness, data inconsistency, the presence of duplicates and some outliers beyond acceptable range. Revealed failures can be used to improve the electronic document interchange between operator community and Federal Service for Supervision in the Sphere of Telecom, Information Technologies and Mass Communications taking into account the recommendations, presented in the paper, such as electronic form improvements and operators’ self-check as part of document workflow.
