Modeling and Evaluation of On-Line User Behavior. Final Report to the National Library of Medicine.
Penniman, W. David
This investigation of search patterns associated with the MEDLINE database had four primary objectives: (1) to refine the stochastic process method of evaluating user behavior; (2) to examine user search behavior exhibited when selecting documents sets; (3) to identify factors that affect the patterns of user behavior; and (4) to use data from the National Library of Medicine (NLM) MEDLINE system to develop a model of ineffective user behavior. Samples of online session protocols obtained from NLM's online system ELHILL-3 were processed in three major phases: the recovery of individual MEDLINE user sessions from the transaction tapes, parsing the individual user and system transactions to assign a unique activity code, and the analysis of user/system behavior using the parsed sessions. The data obtained were analyzed by user ID, daily usage, and level of activity, as well as selected variable analysis and fragment analysis. Findings are outlined and compared with prior studies, and the results of data analyses are summarized for each of seven hypotheses. The methodology and results are detailed, and a need for additional research in the area of search effectiveness is indicated. Twenty references are listed. (RAA)
