Shaw, W. M., Jr.
Information Processing and Management, v26 n6 p693-718 1990
These two articles discuss clustering structure in the Cystic Fibrosis Document Collection, which is derived from the National Library of Medicine's MEDLINE file. The exhaustivity of four subject representations and two citation representations is examined, and descriptor-weight thresholds and similarity thresholds are used to compute cluster-based retrieval effectiveness.
