Which functions are supported by a Conceptual Index within Relativity?

The Conceptual Index within Relativity is designed to enhance search capabilities by leveraging machine learning and natural language processing techniques. Each of the functions mentioned plays a critical role in how users can discover and organize their data effectively.

Keyword Expansion allows users to broaden their search terms to include synonyms or related terms, making it easier to find relevant documents even when the exact keywords are not present. This feature is essential for comprehensive document review, ensuring that all pertinent information is accessible.

Concept Search takes this a step further by enabling users to search based on the meaning of the text rather than just keywords. This allows for a deeper understanding of the context and relevance of documents, which is particularly useful in legal and investigative scenarios where underlying concepts may be more significant than specific words.

Categorization is another key function supported by the Conceptual Index, enabling the automatic classification of documents into various categories based on their content. This automated process helps streamline the organization of data, making it easier for users to manage large volumes of documents by grouping similar items together.

Thus, since all these functions—Keyword Expansion, Concept Search, and Categorization—are integral to the Conceptual Index's capabilities, the correct answer is that it supports all of the above functions.
