Ellis信息查询行为模型的演化研究

Research on Evolution of Ellis’s Model in Information-Seeking Behavior

信息查询模型的研究仍处于前理论阶段,改进和完善现有模型具有重要的意义。采用文献调查法和案例分析法分析了Ellis模型的演化历程,包括Ellis模型的扩展模型、Ellis模型的阶段化、Ellis模型的策略化以及Ellis模型与其他模型结合的内容和特点。指出Ellis模型演化的内因源于其非情境性和适应性,提出要丰富和深化信息查询理论,促进Ellis模型的应用和发展,需要明确设置具体情境,准确界定行为特征,加强与其他信息查询模型的交融,指导信息查询系统的交互设计。

The research on the information seeking models is still in the pre-theoretical stage.Improving and perfecting the existing models remains highly significant.This article,using the literature investigation method and case analysis method,analyzes the content and the characteristics of the evolution of Ellis’s model,including the extended models of Ellis’s model,the stages of Ellis’s model,the strategies of Ellis’s model,and the integration of Ellis’s model with other models,thus points out that the non-situational and adaptive nature drives the evolution of Ellis’s model.In order to enrich and deepen the information seeking theories,promote the application and development of Ellis’s model,it proposes clearly setting the application context,accurately defining the behavioral characteristics of Ellis’s model,promoting Ellis’s model integration with other information seeking models,and guiding the interactive design of the information seeking systems.
