    • Use ServiceNow® pre-built vocabulary for software and hardware terms so the system recognizes their multiple variations in utterances.

    Your Natural Language Understanding models contain pre-built vocabulary settings you can use when adding an example utterance. The vocabulary provides definitions for software and hardware terms whether they're expressed in slang or professional usage. The vocabulary can also recognize product misspellings.

    For example, for one of your example utterances, you enter I need to order a Mac. When the system recognizes a pre-built vocabulary item, the term has a blue line under it.

    Example utterance showing how pre-built vocabulary appears with a blue line underneath the word.
    When you click the word, a window appears with two options to choose for the word:
    • A pre-built suggested definition for the word
    • An option to add a synonym
    Example utterance showing the options users can choose to define the pre-built vocabulary: by choosing the system recommendation or by entering a synonym for the word.

    If you select the first option and click Confirm, the system uses the pre-built suggested definition and the blue line disappears.

    If you select the second option, enter a synonym for the word, and click Confirm, the word and the synonym are added to the model vocabulary.

    If you select either of the two options and click Ignore, the blue line disappears and the word remains as it was previously.
