Abstract

The invention discloses a data quality detection method and system based on a multi-dimensional label. Based on the known type data items and the detection rule base, a multi-dimensional label analysis algorithm is used for marking corresponding dimension labels on the known type data items, and the dimension labels are used for dynamically adjusting the quality detection process of the known typedata items; a quality detection engine is recommended for the unknown type data source by using a rule similarity evaluation algorithm based on the unknown type data item and in combination with a detection rule base, and a result of the quality detection engine is verified to obtain an effective quality detection rule set; and the quality detection process and the effective quality detection rule set of the known type of data items are stored, and the multi-dimensional label rule base is updated. According to the scheme, through a multi-dimensional label algorithm and a rule similarity evaluation algorithm, the problems of poor accuracy, weak timeliness and the like caused by a fixed detection rule template are solved, rapid and accurate detection of data quality is realized, a detectionresult is fed back in time, and the quality of a data source is improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a multi-dimensional label-based data quality detection method and system. Background technique [0002] "Big data" requires a new processing model to have stronger decision-making power, insight discovery and process optimization capabilities, which makes big data a massive, high-growth and diversified information asset. As big data systems in various places are continuously connected to different industries, raw data from a variety of data sources are generated, and after reprocessing, the final information assets are formed. The quality of each data source is the basis for the effectiveness of the big data system. How to quickly and accurately detect whether there are quality problems in various data sources, give early warning and improve the quality of data sources, and reduce the proportion of dirty data in the final information assets , is the key to whet...
