摘要
鉴于相关性模型研究是相关性研究中的核心内容,首先阐释直觉与哲学视角的相关性研究对信息检索领域相关性研 究的借鉴意义,在此基础上,论述信息检索中相关性研究的四维模型(信息源、用户信息需求、时间构件)以及交互模型。其中 对交互模型的阐述,主要集中于认知模型、片段模型及层次模型。
Relevance is the main research issue in infonnation retrieval and information science, and so are relevance models in relevance research. This paper explores the theoretical work about relevance from philosophy as well as intuitive understanding. A four-dimension model(information resource, representation of user's problem time and components) and an interactive model are critically illuminated. A better understanding of the cognitive model, the episode model and the stratifiend model is of great importance to the interactive model.
