• Duplication of concepts in UDC

      Buxton, Andrew; UDC Consortium (UDC Consortium, 2011-07)
      The paper describes a problem particular to universal knowledge classifications with a disciplinary structure. These types of classification present concepts subsumed to the disciplines in which they are studied and thus have to resolve the problem of concepts being repeated in different fields of knowledge. The author looks into how the impact the repetition of concepts in the UDC disciplinary structure may have on information retrieval. He considers advantages and disadvantages of different approaches in presenting re-used concepts in the scheme.
