【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。
[Abstract]:[Objective] To realize the deep connectivity of fragmented knowledge in the network community by constructing a knowledge element link system, so as to effectively guide the horizontal expansion and vertical depth of user knowledge exploration. [Methods] Firstly, domain knowledge base was constructed, and then semantic association of knowledge elements in the knowledge base and the common of user generated content (UGC) resources were fused. The similarity is used to generate knowledge element links, and then the knowledge elements in UGC documents are identified to point to the automatically generated knowledge element content page. [Results] Taking the Clove Garden Cardiovascular Forum as an example, 2111 concepts in the cardiovascular field are extracted, 5 741 pairs of fine-grained concepts are associated, and 5 020 posts are labeled with knowledge elements and the chain is self-directed. Knowledge element content pages are generated dynamically. [Limitation] Only focus on the use of knowledge element linking system in individual knowledge element organization, but not on the macro level of knowledge organization. Multidimensional association has strong usability and adaptability.
