Abstract: A unit and system to validate and correct clinical summary reports includes a parser to parse a clinical summary report and at least one associated source report at document, table and cell level and to generate a table object for each table in each report together with a matrix of cells for each table, each matrix cell represented as a table cell object having an index; an identifier to identify each individual table cell object, a fingerprint generator to determine a semantic fingerprint for each cell object, including a value, header text and row and column information; a cell matcher to match clinical study report table cell objects with corresponding linked source report table cell objects using the fingerprint; and a validator to compare values between the matched clinical study report table cell objects and the at least one associated table cell source report objects to provide a validation decision.
