Dark data describes data that organizations collect however don’t use or analyze. Uncovering valuable insights from darkish knowledge whereas maintaining its high quality is a rising concern. Organizations should be ready to find the totality of an individual’s data virtually instantly and with out missing even a fraction of the collected knowledge because of inaccurate or inconsistent information. All knowledge sourced from a 3rd get together to organization’s inner teams might undergo accuracy (DQ) verify in opposition to the third party information. These DQ check results are useful when administered on data that made multiple hops after the point of entry of that knowledge however earlier than that data becomes licensed or saved for enterprise intelligence. All knowledge having attributes referring to Reference Data in the group may be validated towards the set of well-defined legitimate values of Reference Data to discover new or discrepant values through the validity DQ examine.
Data quality guidelines are an integral element of information governance, which is the method of developing and establishing a defined, agreed-upon set of rules and standards by which all data across an organization is ruled. Data quality is the measure of how well suited a knowledge set is to serve its particular purpose. Measures of knowledge high quality are based on knowledge quality characteristics similar to accuracy, completeness, consistency, validity, uniqueness, and timeliness. As the old saying goes, “garbage in, rubbish out”, and this holds true for machine learning algorithms as properly.
