The method comprises providing a reference data set comprising a plurality of records, each record comprising a plurality of attributes. The method comprises further assigning each of the plurality of records an initial surrogate identifier value, assigning a plurality of block identifiers to each of the records by applying a locality sensitive hashing function to a predefined attribute of the records, resulting in the plurality of the block identifiers, and determining a final surrogate identifier value to each of the records assigned to one of the blocks such that the final surrogate identifier values in each block are uniformly distributed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multicriteria record linkage with surrogate blocking keys","description":"A computer-implemented method and a related system for record linkage of an incoming record to a reference data set may be provided.
