🕙  2 minute read

Use this action to automatically identify and extract important phrases from text and save the results to a data table.

This action is useful for any team, industry, or use case and can add a level of analysis to work that would be impossible to do by hand.

Use case

  • Collect topical information from incoming client emails and pre-populate a Salesforce account with the key phrases.
  • Integrate this action as part of a candidate application process to collect pertinent application information.

How to configure this action

Fields for this action

  • Text

    • Enter a block of text to analyze.
  • Output Field Prefix

    • To help keep output fields organized, choose an output field prefix to add to the beginning of each output field name as this action may output more than one field.
    • The step’s name is used as the prefix by default.

What will this output?

This action will output:

  1. All key phrases found from the Text field
  2. A confidence score for each phrase
  3. The beginning and ending position of each phrase.

Phrases are typically multi-word noun phrases which include at least 1 noun and adjective. The confidence score is the confidence the action has that the phrase is a noun phrase. A higher score is more confident.

This action may generate multiple fields. To help keep output fields organized, the prefix above will be added to the beginning of each of the output field names, separated by two dashes. Each field will result as:{{output-field-prefix--output-field}}. Learn more
