摘要
[目的/意义]将知识的控制单位由"文献"深化到"知识元",是知识发现和利用的关键问题。[方法/过程]文章在分析知识元本质的基础上,明确了知识元的语义结构,构建了知识元语义描述模型。进一步从内容情景角度对学术文献内容结构进行了语义属性分析,通过对学术研究过程进行抽象提出了学术文献内容情景模型,详细说明了文献内容情景的概念、结构、组成要素和语义模型,并给出了实例描述。[结果/结论]学术文献的内容情景是学术研究过程的整体抽象,其本质是学术文献宏观结构层面和微观内容层面的语义概念模型,影响着知识元抽取、标引和关联的质量,规范、控制和制约着知识元的逻辑组合。研究表明,该模型有利于语义揭示深入到知识单元,为细粒度的知识组织与发现提供了新的视角。
[Purpose/significance] Refining the knowledge control unit from "document" to "knowledge element" is the key problem in knowledge discovery and utilization.[Method/process] On the basis of analyzing the essence of knowledge elements,this paper clarifies the semantic structure of knowledge elements and constructs a semantic description model of knowledge elements.Furthermore,the paper analyzes the semantic attributes of academic literature content structure from the perspective of content scenario.By abstracting the process of academic research,the paper proposes an academic literature content scenario mode,which describes the concept,structure,composing elements,and semantic model in detail,and provides the examples.[Result/conclusion] The content scenario of academic literature is the overall abstraction of the academic research process.Its essence is the semantic conceptual model of the macro-structure level and micro-content level of academic literatures,which affects the quality of knowledge element extraction,indexing and association,and regulates,controls,and restricts the logical combination of knowledge elements.Results show that this model is conducive to the semantic disclosure to the knowledge unit,and provides a new perspective for fine-grained knowledge organization and discovery.
