Classifier Model Reference Data

A classifier model contains a reference data column that can include sentences, paragraphs, or pages of text. The reference data represents the different types of text input that a Classifier transformation can read in a mapping. When you create a model, verify that the reference data includes the types of text that you expect to find when you run the mapping.
You can use the mapping source data to create a classifier model. Select a sample of the source data and copy the data sample to the model.
Consider the following rules and guidelines when you work with classifier model reference data:
  • A reference data field can be of any length. You can enter pages of text into each data field.
  • You import reference data from a data object.
  • You cannot edit reference data values. However, you can delete a data row.
  • When you compile a classifier model, the compilation process disregards any number values in the reference data.
