基于碎片化检索的数字图书馆知识组织与揭示研究

Research on Knowledge Organization and Revelation of Digital Libraries Based on Fragmentation Retrieval

碎片化检索是指将用户的需求信息拆分成具有独立含义的一个或多个词语的检索。检索对象主要包括用户需求信息和馆藏资源特征信息。碎片化检索可以提高数字图书馆的服务质量,为优化馆藏资源结构提供支持,提高馆藏资源利用率。基于碎片化检索的数字图书馆知识组织与揭示原则包括科学性、系统性、标准化、特色化、共享性、安全性。建议从用户端、后台管理端及技术支持3个方面对知识组织与揭示系统进行功能设计,进而构建相应模块。

Fragmentation retrieval refers to the retrieval of needed information of users into one or more words with independent meaning.The retrieval objects mainly include the needed information of users and collection resource characteristic information.Fragmentation retrieval can improve the quality of services of digital libraries,provide support for optimizing the collection resource structure,and improve the collection resource utilization.The principles of knowledge organization and disclosure of digital libraries based on fragmentation retrieval include being scientific,systematic,standardized,distinctive,shared,and secure.It is recommended to design the functional organization of knowledge organization and disclosure system from the three aspects of user terminal,background management terminal,and technical support,and then build corresponding modules.
