【目的】协同信息检索系统是协同信息检索的工具,本文为协同信息检索研究及系统开发提供参考。【方法】采用典型案例研究法和比较分析法,分析Annotate!、Cerchiamo、CoSearch和SearchTogether等4个国外典型协同信息检索系统在框架结构、支撑技术、实现功能和性能评价方面的异同。【结果】显性协同信息检索系统支持同步检索,采用用户界面调节,多为C/S结构,采用即时信息和自动分工技术,功能较丰富;而隐性协同信息检索系统支持异步检索,采用深层算法调节,多为多层次结构,采用数据或代理技术,功能较单一。【局限】由于协同信息检索系统目前还处于实验开发阶段,未能对各系统进行体验式研究。【结论】协同信息检索系统开发没有固定模式,需根据用户功能需求进行选择,并采用相应支持技术。
【Objective】 Collaborative information retrieval system is a tool for collaborative information retrieval. This paper provides a reference for collaborative information retrieval research and system development. 【Method】 The case study and comparative analysis were used to analyze the similarities and differences in framework structure, support technology, implementation function and performance evaluation of four typical collaborative information retrieval systems from Annotate, Cerchiamo, CoSearch and SearchTogether. 【Result】 The explicit collaborative information retrieval system supports synchronous retrieval, with user interface adjustment, mostly C / S structure, the use of instant messaging and automatic division of labor technology, features more rich; and hidden collaborative information retrieval system supports asynchronous retrieval, the use of deep Algorithm adjustment, mostly multi-level structure, the use of data or proxy technology, more single-function. [Limitations] As collaborative information retrieval system is still in the experimental development stage, the system can not be experiential research. 【Conclusion】 There is no fixed pattern in the development of collaborative information retrieval system, which needs to be selected according to the functional requirements of users and the corresponding supportive technologies should be adopted.
