Decomposing DDC synthesized numbers

Abstract

Some empirical studies have explored the direct use of traditional classification schemes in the online environment; none has manipulated these manual classifications in such a way as to take full advantage of the power of both the classification and computer. It has been suggested that this power could be realized if the individual components of synthesized DDC numbers could be identified and indexed. Looks at the feasibility of automatically decomposing DDC synthesized numbers and the implications of such decompositions for informational retrieval. 1.701 sythesized numbers were decomposed by a computer system called DND (Dewey Number Decomposer). 600 were randomly selected for examination by 3 judges, each evaluating 200 numbers. The decomposition success rate was 100% and it was concluded that synthesized DDC numbers can be accurately decomposed automatically. The study has implications for information retrieval, expert systems for assigning DDC numbers, automatic indexing, switching language development and other important areas of cataloguing and classification
