These groups are: (1) experimentalists, (2) repeat users, (3) latent users, and (4) dropouts. The past information gathering behavior preference patterns of the individual users serve as input. The output of this model, the prediction of demands, is in terms of the total numbers of current active and inactive users for each projected time period. Besides making systems managers cognizant of these two main types of users, the active and the inactive, who support a system, this model, also demonstrates the effects of the trial rates and the repeat use rates upon the future success of the service, i.e., success in terms of continues use of the system. The library Demand Model is applied to several different types of existing information and library services, (e.g., book delivery system, on-line bibliographic retrieval systems), to ascertain its capabilities. |
