Abstract: Method and apparatus for using similarity analysis, and a plurality of different machine learning algorithms to detect parsing errors or missing data in data tables. The AI system can then generate a new data table with the errors corrected. The corrected data table can include predicted values of what the original data table was missing. The AI system offers an improvement for generating data tables with range values where such data tables are normally produced with errors and missing information. The AI system provides an automatic way of correcting errors, via the generation of a new data table.
