 Controlled vocabulary emerges as a tool for managing lexical variations and semantic similarities, which in turn, foster efficient data organization, categorization, and information retrieval.


Controlled vocabulary in AI is used to streamline and simplify machine learning and Natural Language Processing (NLP) tasks. It helps in reducing the complexity of language, thus improving the understanding and performance of AI systems. For example, in text analysis or semantic search, a controlled vocabulary can guide AI systems to comprehend that different terms like “AI”, “Artificial Intelligence”, and “Machine Intelligence” essentially refer to the same concept. This recognition significantly improves the system’s ability to fetch accurate and relevant results.

Building and maintaining a controlled vocabulary within AI presents challenges. It requires a deep and evolving understanding of a given field, staying updated with changes in language use, and careful management to prevent erroneous associations. Despite these challenges, well-devised controlled vocabulary enhances the accuracy and efficiency of AI systems, improving responses and results in tasks like document retrieval, data analysis, content recommendation, and more.
