图书馆联盟信息共享:内容、模式与评价

Library Consortium Information Sharing: Content,Model and Evaluation

文章在分析图书馆联盟信息共享内容及障碍的基础上,结合现阶段我国图书馆联盟组织合作模式,总结出联盟信息共享模式的表现形式,即集中式、顺序式和互惠式。为了比较不同信息共享模式的信息传递效率,本文运用信息时效熵和质量熵理论对图书馆联盟信息共享模式进行了评价分析。通过该评价理论,计算出集中式信息共享模式信息时效熵值和质量熵值最小,与其他两种信息共享模式相比具有总体优越性。

Based on the analysis of the content of and obstacle to library consortium information sharing, and combining with the present organizational and cooperative modal of the hbrary consortium in China, this paper sums up the forms of library consorti um information sharing model, namely, centralized model, sequential model and reciprocal model In order to compare the infor mation transfer efficiencies of the different information sharing models, the paper uses the theory of information aging entropy and quality entropy to evaluate and analyze the library consortium information sharing model. By the use of this evaluation theory, the paper concludes after calculation that the value of information aging entropy and quality entropy under the centralized information sharing model is the minimum. Compared with the other 2 information sharing models, the centralized model has the overall superi orities.
