Word Tree Data Preparation
Since a Word Tree gets confused by inconsistent whitespace and punctuation, we might use this component to prepare some text for Word Tree Analysis.
For example, suppose we run two ReplaceAll task with the following configuration:
| REGEX | REPLACEMENT STRING | DESCRIPTION |
|---|---|---|
| [,".] | '' | Remove all commas, double quotes and periods from the text. |
| \s+ | ' ' | Replace all multiple whitespace with a single space. |
Below is the before and after having run these two TrimAll task. Notice that all of the punctuation has been removed.
