Table Based Data Set Extraction From Data Clusters

A computer system and computer implemented method for extracting data set from data clusters that comprises of rows and columns of heterogeneous data values. A plurality of random data groups comprising of at least one of a plurality of contiguous row or columns of data values are selected. Each data value has a data type. A table template type is identified based on detection of a pattern between the data cells of the contiguous rows or columns. A table template header is identified that comprises of a starting position, and ending position and a width. A reference row or reference column indicating a start of a table body is determined. The data cells of the subsequent rows or columns in the table body are compared to the data cells of the reference rows to identify noise rows or columns that are removed from the table body.
