Fecha de publicación: 30/11/2023 Fuente: Wipo "BigData" The present invention relates to a big data evaluation method and system. The method comprises steps of: determining evaluated data, reference data and different statistical indexes for data evaluation according to a preset experimental requirement; performing comparative calculation according to the evaluated data, the reference data and the statistical indexes to obtain corresponding numerical values of the statistical indexes; normalizing the numerical values of the statistical indexes to obtain normalized data; establishing a multi-dimensional spatial coordinate system according to the normalized data, and determining a distance value between the preset evaluation data and the reference data according to the multi-dimensional spatial coordinate system; and judging the comprehensive simulation capability of the evaluated data according to the distance value. The present invention can be applied to all natural sciences and social sciences involving data quality evaluation or object prioritization, and can quantify the comprehensive precision of multiple variables of different models.
