Title versus title/abstract text searching in SDI systems

Abstract: The terms from 228 individual SDI profiles of 104 research chemists were matched against the citations retrieved by these profiles in eight consecutive runs of Basic Journal Abstracts to determine the number of citations that would have been retrieved for each individual user if titles only had been searched. Computing the data as a ratio of title hits to total hits, the mean percentage of retrieval of citations if only titles are searched when compared with searching of titles and abstract text was 27.0%. This represents an average loss of 73% of the potential output to the individual SDI user. One can expect a higher level of retrieval by titles alone if only a single term is required for a match than in searches requiring more than one term to be present to constitute a match (39% compared with 16.8% in this study).
