【摘要】 文章基于用户需求的学科信息环境的概念、基本架构、组成要素,分析了学科信息环境及各主要功能模块组成要素的信息传递模式及其在学科信息服务中的作用。认为学科信息环境中信息的传递模式除单向、双向、多向主动(被动)传递外,还有超越上述概念的更为复杂的信息传递模式———搜索传递、组合传递、社会化传递等模式。学科信息环境中,不同的信息传递模式是相辅相成的,它们在学科信息服务中具有不同的作用,发挥着不同的学科信息传递效益。更多还原

【Abstract】 Based on the concept,basic framework and component elements of the user-demanded Subject Information Environment(SIE),this article analyzes the information transfer modes of the component elements of SIE and its main functional modules as well as their roles in subject information service.The article argues that in addition to one-way,two-way and multiway active(passive) transfer,the information transfer modes in SIE have more complicated modes such as search transfer,combined transfer and social transfer.Different information transfer modes in SIE are complementary to each other,they have different roles and create different subject information transfer benefits in subject information service.更多还原
