1. A computer system for data mining shape based data, the computer system comprising:

  • a data mining computer having a processor, the processor configured to perform a method comprising;

    receiving a shape data for each of a plurality of data entries;

    creating a first abstract from the shape data for each of the plurality of data entries, wherein the first abstract is a graphic illustration of a location of a detected error on a semiconductor chip;

    organizing the first abstracts into a plurality of groups based on a first criterion, wherein the first criterion is the location of the detected error;

    creating a second abstract for each data entry in the plurality of groups based on a second criterion, wherein the second criterion is the shape of the detected error, and information derived from the first abstract, wherein the second abstract is a visual representation of the detected error on the semiconductor chip that illustrates a more detailed view of a common location of detected errors; and

    determining a correlation between each of the data entries in the group based on the second abstract, wherein similarities in the shapes of the detected errors in the common location indicate that the detected errors are not random defects.
