Publication number: 20220358336Abstract: An Artificial Intelligence (AI)-based data matching and alignment system identifies similar data sources for a target data source from a data corpus and generates a knowledge graph that enables downstream applications seamless access to data in the data corpus. The system extracts column features at different levels for the target data source and a plurality of data sources from the data corpus. Feature matrices are built from the features of the target data source and the plurality of data sources. Candidate data sources similar to the target data source are filtered from the plurality of data sources using the feature matrices. The tree-based similarity is estimated and K Nearest Neighbor (KNN) graphs are built to identify columns from the candidate data sources that are similar to columns of the target data source to build the knowledge graph.Type: ApplicationFiled: August 25, 2021Publication date: November 10, 2022Applicant: ACCENTURE GLOBAL SOLUTIONS LIMITEDInventors: Neda ABOLHASSSANI, Maziyar Baran POUYAN, Teresa Sheausan TUNG, Andrew FANO, Sayantan MITRA
