【目的】针对IR建设中普遍存在的内容不足与利用效率不高的问题进行实践性方法探索。【应用背景】在国内外多数IR数据量少且用户服务功能不够丰富的背景下,开展中国农业大学机构知识库(CAUIR)内容广泛收集与扩展服务建设。【方法】基于CAUIR的工作实践,从IR内容建设和服务功能扩展两方面,说明构建服务可扩展型IR的具体技术措施,并用统计数据证明扩展IR服务功能可提高内容的利用率。【结果】CAUIR服务已扩展到13个专题,形成了系列服务。6年来用户登录总量超过1 129万,日均超过5 000。【结论】实践证明扩展面向普通用户的IR服务功能是提高IR内容利用效率的有效措施。
【Objective】 Practical methods are explored to solve the problems of insufficient content and inefficient utilization in IR construction. 【Background】 With the majority of domestic and international IR data less and the user service function is not rich enough, the content of CAUIR should be widely collected and expanded. 【Method】 Based on the working practice of CAUIR, the concrete technical measures of constructing scalable IR service are described from two aspects of IR content construction and service function expansion. And the statistical data prove that extending IR service function can improve the utilization of content. 【Result】 CAUIR service has been extended to 13 topics, forming a series of services. Over the past 6 years, the total number of user logins has exceeded 11.92 million with a daily average of over 5 000. 【Conclusion】 It has been proved that expanding the IR service function for ordinary users is an effective measure to improve the efficiency of IR content utilization.
