  2. Federal Controlled Vocabularies • What Are They • Examples • Discussion

  3. 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) • Tutorialhttp://www.slis.kent.edu/~mzeng/Z3919/1need.htm 1 Working Council of CIOs, Business Wire, Feb 27 2001
