RandomSentence

The RandomSentence transformer is designed to populate specified database columns with random sentences. Ideal for simulating natural language text for user comments, testing NLP systems, or anonymizing textual data in databases.

Parameters

Name	Description	Default	Required	Supported DB types
column	The name of the column to be affected		Yes	text, varchar
keep_null	Indicates whether NULL values should be preserved	false	No	-

Description

The RandomSentence transformer employs complex text generation algorithms or libraries to generate random sentences, injecting them into a designated database column without the need for specifying sentence length. This flexibility ensures the creation of varied and plausible text for a wide range of applications.

Example: Populate random sentences for the comments table

This example shows how to configure the RandomSentence transformer to populate the comment column in the comments table with random sentences. It is a straightforward method for simulating diverse user-generated content.

RandomSentence transformer example

- schema: "public"
  name: "comments"
  transformers:
    - name: "RandomSentence"
      params:
        column: "comment"
        keep_null: false

In this configuration, the comment column will be updated with random sentences for each entry, replacing any existing non-NULL values. If keep_null is set to true, existing NULL values in the column will be preserved, maintaining the integrity of records where comments are not applicable.
