Models of human behavior in information seeking tasks

摘要

Models of human information seeking in searching online bibliographic citation networks are discussed. First, the experimental environment called DBASE (Data Base Access and Search Environment) and the results from two previous experiments are briefly reviewed. Rule-based and decision theoretic approaches to modeling the search task are then presented and a progression of models is developed. The models are used to derive “optimal” search strategies when both constrained and unconstrained by experimental data. Finally, the rule-based model is used to mimic subject performance and the differences between model and subject performance are considered.
