Why a Controlled Vocabulary?Improve effectiveness of information storage and retrieval systemsKnowledge workers spend 25-35% of their time searching for information with 50% success1

  • The need for vocabulary control arises from two basic features of natural language, namely:

    • Two or more words or terms can be used to represent a single concept

      • Example: salinity/saltiness   VHF/Very High Frequency

    • Two or more words that have the same spelling can represent different concepts

      • Example: Mercury (planet)   Mercury (metal)   Mercury (automobile)   Mercury (mythical being)
