When you add a step to a labeler asset, Data Quality prompts you to define a step with a character set or with a dictionary.
The following image shows the options that you configure when you define a step with a dictionary:
The dictionary options include the following properties:
Labeler mode.
Indicates the type of labeling operations to perform on the input data.
Add Step option.
Adds a step to the asset. A step describes a labeling operation that a mapping can apply to an input data field.
Up and Down options.
Moves a step that you select up or down within the step sequence.
Step sequence.
Defines the order in which a mapping applies each step to the input field at run time. The mapping performs labeling operations in the order that you specify.
Options name.
Identifies the dictionary that you add to the step.
Test input field.
Contains the input data that the Secure Agent uses to test the steps in the labeler sequence.
Test output fields.
Contain the result of the test. The test output field contains a copy of the input field data in which any dictionary value is replaced by the label that you specify.
Import file option.
Imports data to the test panel.
Step type.
Identifies the type of step to which the properties apply.
Dictionary name.
Identifies the dictionary that the step applies to the input data. You select the dictionary.
Label name.
Specifies the label that the step applies to the characters in an input string. You enter a single character as the label.
The labeling operation returns the label for each character in a matching dictionary value.
Casing option.
Specifies whether the step considers the character case of the input values that it compares to the dictionary values. For example, the character case may be relevant if you plan to label person names from an input string, as person names begin with an uppercase letter.
Clear the option if the character case is not relevant to the type of data that you plan to label from the inputs.
Override any later step in the sequence option.
Determines whether the current step output overrides the output from later steps in the sequence.
Ignore Text option.
Adds a character to ignore during a labeling operation. You can add one or more characters. The labeling operation does not assign the label to any character that matches a character in the dictionary.
The
Ignore Test
option includes the following properties:
Search term. Specifies the characters to ignore when you perform a labeling operation.
Case sensitive. Determines whether the input characters must match the case of the search characters.
Uppercase. Converts the characters in the input string that match the search term to uppercase.
Start position. Specifies the character position in the input string at which the asset starts to analyze the characters.
End position. Specifies the character position in the input string at which the asset ends the analysis.
