Abstract: ［Purpose/Significance］The essence of information retrieval is a cognitive process, so it is significant to study the model of interactive information retrieval which could improve users’ cognition.［Design/Methodology］Based on the constructivism theory and targeting at promoting users’ cognitive development, this study established a model of interactive information retrieval system with a top-level analysis framework consisting of information space layer, user space layer and interface interaction layer. A prototype system was also developed.［Findings/Conclusion］The experiment results show that the prototype system can facilitate users in exploring information space, and help users construct cognition and develop cognitive space.［Originality/Value］Cognitive constructivism is applied in the field of information retrieval, and suggestions for improving the interactive design of IR system are proposed from the perspective of cognitive construction, which are beneficial to provide cognitive supports.
