Title

¬The value of structured abstracts in information retrieval from MEDLINE

Source

Health libraries review. 14(1997) no.3, S.157-166

Year

1997

Abstract

Presents a structured abstract of the actual article. Outlines the debate on the value of structured abstracts and describes a research project into their use, which investigated records of cardiovascular disease downloaded from MEDLINE and tested against clinical questions derived from a survey of CD-ROM use in 3 health science libraries. It was found that structured abstracts improve precision at the expense of recall and place heavier demands on the skills of selecting fields to search within the abstract. Indicates directions for further research
