Abstract
A method, computer program product, and computer system for detection and utilization of similarities among tables in multiple data systems that include a first data system and a second data system. A semantic dataset is generated. A first measure (X) of similarity between semantic data in columns of the first and second data systems is computed using the semantic dataset. A first, different measure (Y) of similarity between semantic data in columns of the first and second data systems is computed using the semantic dataset. A third measure (Z) similarity between columns of the first and second data systems is computed based on data in cells within the columns. A weighted combination (U) of X, Y, and Z between the columns of tables in the first and second data systems is computed. X, Y, Z, U or combinations thereof are used to improve a computer system.
