Title

Ordering author and work records : an evaluation of collocation in online catalog displays

Source

Journal of the American Society for Information Science. 47(1996) no.7, S.538-554

Year

1996

Abstract

To investigate the extent to which online catalogs arrange together, or collocate, records representing particular authors and works, a survey compared the displays resulting from 5 author and 5 work queries in 18 online catalogs. Dependent variables to measure collocation included the number of items irrelevant records were interfiled among relevant records. Searches for worst-case authors and works associated with large retrieval sets, including 'Homer' and 'Paradise lost', revealed the effects of Boolean versus string matching, query type, and catalog size on the collocation of relevant records. Results of the survey showed that string matching collocated relevant records more successfully than Boolean matching, that author records were collocated more successfully than work records, and, surprisingly, that catalog size had only a small effect on collocation
