摘　　要：【目的】通过构建知识元链接体系,实现网络社区中碎片化知识的深度连通,以有效引导用户知识探索中的横向扩展和纵向深入。【方法】首先构建领域知识库,再融合知识元在知识库中的语义关联和在用户生成内容(UGC)资源中的共现相似度以生成知识元链接,随后对UGC文档中的知识元进行标识,指向自动生成的知识元内容页。【结果】以丁香园心血管论坛为例,抽取心血管领域内概念单元2 211个,细粒度概念关联5 741对,对5 020条帖子内容进行知识元标注,链向自动生成的知识元内容页面。【局限】仅关注知识元链接体系在个体知识单元组织中的利用,尚未在知识组织宏观层面就其开展探索。【结论】知识元链接体系在不改变网络社区中现有的资源组织架构的前提下,实现了知识元、UGC文档的多维关联,具有很强的可用性和适应性。[Objective] This paper proposes a system to link the fragmented knowledge elements from an online community, aiming to help explore knowledge more effectively. [Methods] First, we built a domain knowledge base for the online community. Then, we combined units of the domain knowledge base with the semantically similar elements of the user-generated-content（UGC）. Finally, we identified the knowledge units of the UGC and linked them with relevant Web pages. [Results] We examined the proposed method with a Chinese cardiovascular BBS site. A total of 2,211 cardiovascular concepts and 5,741 fine-grained relations were extracted to create the domain knowledge base. We identified the knowledge elements from 5,020 posts automatically and linked them with relevant webpages. [Limitations] Only investigated the linking of knowledge elements at the micro level. [Conclusions] The proposed system can effectively establish connections between knowledge units and UGC documents based on the existing resource organization schemes. The new method could be used in other fields.
