A Feature Analysis of Interactive Retrieval Systems. Final Report.
Martin, Thomas H.
The command language features of 11 on-line information retrieval systems are presented in terms of the functional needs of a searcher sitting at a terminal. Functional areas considered are: becoming familiar with the system, receiving help when in trouble, regulating usage, selecting a data base, formulating simple queries, expressing single concepts, interconnecting concepts, displaying results simply, and controlling the display. Features felt most essential to on-line searching are live help, users' guides, boolean operators, search field control, suffix removal, relational operators, dictionary access, request sets, search review, pre-defined formats, on-line formatting, and off-line printing.
