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 and obstacles of information sharing in library alliance, this paper summarizes the manifestations of alliance information sharing modes, namely centralized, sequential and reciprocal, based on the current cooperation model of library alliance in our country. In order to compare the information transfer efficiency of different information sharing models, this paper uses the information age entropy and quality entropy theory to evaluate and analyze the model of library information sharing. According to the evaluation theory, the information of centralized information sharing mode has the smallest value of the entropy of aging and the quality of entropy. Compared with the other two information sharing modes, it has the overall superiority.
