Classify Text integrates the functionality provided by the Text Classification API, which allows you to assign one or more classes to a document according to their content. Classes are selected from a previously established taxonomy which can come from a well-defined standard or from your own definition using the classification models customization console.
On the right, you can see the interface that appears when you select the Classify Text action.
There are four elements in the interface: Type, Model, Relevance Filter, and Max number of categories.
Depending on the value selected, an additional field will appear to include either the text or the URL to analyze.
There are two different fields in the output of the Classify Text action: categories and category_tags.
category_tags: this field returns a list of the categories found in the text separated by commas. In this list, only the last step of the category hierarchy is shown (for the taxonomies provided by MeaningCloud).
