Title

Comparing the document representation of two IR-systems : CLARIT and TOPIC

Source

Journal of the American Society for Information Science. 44(1993) no.7, S.383-392

Year

1993

Abstract

Discusses the TOPIC and CLARIT information retrieval systems in terms of assigned versus derived and precoordinate versus postcoordinate indexing. Compares the document representation of the two systems. Reports on a test done on a small sample of Wall Street Journal articles. The positive results found for CLARIT in earlier test on medical documents were not observed in this general database
