Title

¬A comparison of group and individual performance among subject experts and untrained workers at the document retrieval task

Source

Journal of the American Society for Information Science. 49(1998) no.6, S.517-529

Year

1998

Abstract

Reports on a study that contrdicts the hypothesis that building detailed subject knowledge into search system improves retrieval. A group with a background in molecular biology performed the same judgements when considering document retrieval as another group without subject knowledge. The untrained panel performed better than any of the members of the trained panel and almost at the level of the trained panel as a whole. Explains the method which uses the probability ranking principle to measure retrieval
