What is a benefit of Keyword Expansion in document review?

The benefit of keyword expansion in document review primarily lies in the discovery of additional related terms. Keyword expansion is a process that helps identify synonyms, variations, or contextually relevant phrases that may not have been initially included in the search criteria. This approach enhances the comprehensiveness of document review by capturing more relevant documents that could be related to the keywords initially specified.

By expanding the list of keywords to include related terms, reviewers can ensure that they are not missing pertinent information that could contribute to their case or analysis. This is particularly important in legal and compliance contexts, where the relevance of documents can hinge on the inclusion of diverse terminologies that stakeholders might use interchangeably.

In contrast, while visual representation of keywords and increased search speed might provide some benefits during the review process, they do not directly contribute to the primary goal of enhancing relevancy through the discovery of related terms. Similarly, the reduction of data size is typically a goal of data management strategies rather than a function of keyword expansion.
