Configuring a Weighted Average Transformation

Configuring a Weighted Average Transformation

You use the Weighted Average transformation to adjust the overall match score that a mapping generates for a series of match analysis operations. You edit the relative weights of each input port to reflect the priorities of the data comparisons that you defined for the source data set. Each input port on the Weighted Average transformation represents a match score output from a Comparison transformation strategy.
The following steps describe the process to configure a non-reusable Weighted Average transformation in a mapplet or mapping that uses Comparison transformations.
  1. Open a match analysis mapplet or mapping, and add a Weighted Average transformation downstream of the Comparison transformations.
  2. Connect the score output from a Comparison transformation to a Weighted Average input port.
    Repeat this step for other Comparison transformations in the mapplet or mapping.
  3. Select the
    Ports
    tab on the Weighted Average transformation.
  4. Double-click the
    Weight
     field for each input, and enter a weight value between
    0.001
     and
    1
    . The weight value should reflect the relative importance of the input score when compared to other inputs on the transformation.
  5. Save the mapplet or mapping.
