中文摘要：

图书馆知识社区是泛在知识环境中增加馆员和读者、读者和读者的信息交流与互动的重要途径。对社区资源进行合理有效的表示是图书馆知识社区有效进行知识管理和满足用户需求的关键。在分析图书馆知识社区信息资源和用户需求特点基础上,文章尝试将传统的框架表示法和谓词逻辑表示法相结合对图书馆知识社区相关资源进行表示,这一混合表示法采用框架表示法对资源属性等结构化的信息进行表示,采用谓词逻辑表示法将自然语言等非结构化的信息表示成结构化的语言,并用例子说明如何采用这种混合方法来处理图书馆知识社区中的结构化和非结构化信息的表示问题。

英文摘要：

Library knowledge community is an important way to increase information communication and interaction between the librarians and readers as well as readers and readers in ubiquitous knowledge environment. Reasonable and effective representation of community resources is the key to carry out knowledge management and meet the needs of the users. According to the features of information resources and users＇ needs of library knowledge community,this paper attempts to combine frame representation with predicate logic representation in order to describe resources in library knowledge community. The hybrid method uses frame representation to describe structured knowledge like resource attributes and uses predicate logic representation method to describe unstructured knowledge like natural language into structured language. The paper also shows an example of how to use the hybrid method to process structured and unstructured knowledge of library knowledge community.
