Controlled vocabularies in indexing

Controlled vocabularies in indexing are standardized lists of specific terms used to categorize and organize information consistently. They ensure that everyone uses the same words for particular concepts, making it easier to find and retrieve related content. For example, in a library, instead of using multiple terms like "car," "automobile," or "vehicle," a controlled vocabulary would specify one preferred term. This system improves accuracy and efficiency in searching, as users and systems share a common language, reducing misunderstandings and enhancing the accessibility of information across databases and collections.
