Abstract

Human selection of periodical references from the full text, for inclusion in the Mass Spectrometry Bulletin, is compared with the retrieval from the same source material by the mechanized current awareness SDI services of CT and ASCA. Results show human selection to have retrieved substantially more references than SDI using brief, high relevance profiles. Experiments with CT using a larger profile show an increase in recall but a drop in precision. Precision is assessed in relation to the selectionrejection policy for the Bulletin, which is briefly discussed. The effectiveness of the SDI services as a means of indicating references in periodicals outside the range of those examined in detail is also discussed.
