在分析情报学的研究人员、机构类型、哲学基础和哲学假设的基础上,尝试构建由元理论、范式理论、方法论和主题理论4个层次组成的情报学理论框架。该理论框架坚持Information和Intelligence功能整合;本体论、认识论和方法论相统一;理论指导实践,却也扎根于实践;高层事物与低层事物相统一的4条基本路线。研究结果表明:情报学的众多方面并非是相互独立的,而是以相互影响的方式存在。 Based on the analysis of researchers, types of institutions, philosophical bases and philosophical assumptions in information science, this paper attempts to construct a framework of information science which consists of four levels: meta-theory, paradigmatic theory, methodology and thematic theory. The theoretical framework insists on the integration of Information and Intelligence functions; the unity of ontology, epistemology and methodology; the theoretical guidance and practice, but it is also rooted in practice; and the four basic unification of high-level things and low-level things. The results show that many aspects of information science are not mutually independent, but exist in an interactive way.
