Text Analysis

Introduction

The Text analysis rule allows you to analyse small or large amounts of text. There are two functions for analysis with the Text analysis rule:

• Sentiment analysis
• Extract key phrases

With each function, the AI is programmed to distil information and meaning from a text block. For example, extract key phrases function is programmed to extract most relevant words or expressions from a block of text. Sentiment analysis on the other hand can be used to give a Positive or Negative result on feedback forms or item reviews and presented in a dashboard, see image below for an example dashboard sentiment analysis:

When to use

Use this rule when you want to analyse large blocks of text into a Positive or Negative result with a percentage score, or when you want to extract key phrases.

You can add this rule:

• to a field
• to a form
• to a process (the rule will run on load)
