What feature allows you to explore similar language expressions for concepts?

The ability to explore similar language expressions for concepts is facilitated by keyword expansion. This feature enhances the search capabilities within the analytics environment by identifying synonyms, related phrases, and various linguistic variations of a keyword. When a user inputs a term, the system can suggest additional relevant terms that can be used to broaden the search or analysis. This is particularly useful for understanding the nuances of language and capturing a wider array of documents or insights that may not contain the exact term but convey similar meanings.

In contrast, the other choices focus on different aspects of keyword handling. Keyword categorization organizes keywords into defined groups, while keyword ranking prioritizes keywords based on certain metrics, such as relevance or frequency. Document similarity analysis assesses the degree of similarity between documents, but it does not specifically address the exploration of related language expressions or variations.
