The CREATE MULTIPLE DICHOTOMY FROM <text> command allows you to apply a taxonomy to a text (open-ended) variable. Crunch reads each response, classifies it to matching categories of the taxonomy and saves the result as a new variable. This command can select several categories for the same response. Use this command when one answer can mention more than one topic. 

The taxonomy can be defined with the DEFINE TAXONOMY command earlier in the same script, or in a previous one, or one created in Crunch UI. The taxonomy must belong to the same project (folder) as the dataset.

Important to remember: 

• The input variable must be a text variable. 
• The output alias must not exist in the dataset yet.

CREATE MATERIAL MULTIPLE DICHOTOMY FROM <text variable alias> USING "taxonomy name" 
AS "alias for output variable"
TITLE "title for output variable";

Example

CREATE MATERIAL MULTIPLE DICHOTOMY FROM <most_important_issue> USING "Created from most_important (2)" 
AS "most_important_mr"
TITLE "Most Important Issues (MR)";

The multiple response variable has one category per category of the taxonomy, plus:

• Unclassified – responses that don't match any category of the taxonomy.
• No data – cases with no responses (missing).
