Keyword - Knowledge organization

• “It is well known that thesauri consist of a selection of concepts supplemented with information about their semantic relations (such as generic relations or “associative relations”). Some words in thesauri are “preferred terms” (descriptors), whereas others are ''lead-in terms.” The descriptors represent concepts. The difference between “a word” and “a concept” is that different words may have the same meaning and similar words may have different meanings, whereas one concept expresses one meaning.“

meaning = concept = descriptor = preferred term → lead-in term

Broughton, Hansson, Hjerland, and Lopez-Huertas (2005) have suggested that the following traditions are the most important ones in KO:

• The traditional approach to KOS expressed by classification systems used in libraries and databases, including the Dewey Decimal System (DDC), the Library of Congress Classification (LCC), and the Universal Decimal Classification (UDC)
• The facet-analytical approach founded by Ranganathan
• The IR tradition
• User oriented/cognitive views
• Bibliometric approaches
• The domain-analytic approach
• Other approaches, including semiotic, “critical-hermeneutical,” discourse-analytic, and genre-based ones, as well as those that place emphasis on document representations, document typology and description, markup languages, document architectures, and so forth
