Specifying word substitutions for a dataset in NLS

Word substitutions enable you to connect common words with valid data specifications when using Natural Language Search (NLS) on Data Visualization datasets.

Common words and phrases have specific meaning in each dataset. In this example, you can see how to specify the meaning of the phrase 'current year' and the word 'domestic' into internal search terms.

  1. Under Word Substitutions, click Add New Item.
  2. In the new row, add a common speech component in the Input word or phrase column.
  3. In the same row, under Internal search term, specify the equivalent term in the dataset.

    In this example, the phrase 'current year' was added with the clause 'year:2019', setting the current year to 2019.

  4. Click Add New Item again, if you want to add more word substitutions.
