Information search and retrieval: a comparative study of three models

Abstract

The paper starts with definitions of key terminologies followed by an overview of the historical context of each search process model. Also figures illustrating theoretical framework is shown. Explanations of the diagrams are given for fuller understanding of the three Information Search Process (ISP) models portraying the varying behaviours of searchers and the techniques involved in handling their information needs. Kuhlthau's model of the ISP, Vakkari's theory of the task-based Information Retrieval (IR) process, and Ingwersen and Jarvelin's cognitive model were examined. The implication of ISP for information services and systems is explained.
