| Abstract: |
In today's big science era,the demand for interdisciplinary knowledge service is becoming more and more urgent. However, as an important platform for interdisciplinary knowledge service, digital library still organizes knowledge according to disciplines by taking document as unit, which makes it difficult to break the barrier between disciplines, resulting in the dispersion of knowledge about the same thing in different disciplines. In order to support interdisciplinary research, the knowledge organization method of digital library needs to go deep into interdisciplinary knowledge organization based on knowledge content.
As the core and foundation of knowledge organization, knowledge representation is the key to solve the interdisciplinary knowledge organization of digital library. To this end, this paper first analyzes the interdisciplinary characteristics of digital library knowledge resources to reveal their commonness and heterogeneity. Secondly, according to the abstraction degree of knowledge, the multi granularity division of library knowledge resources is carried out, and the basic units of knowledge representation are identified.Thirdly, the applicability of existing knowledge representation methods in interdisciplinary knowledge representation is analyzed. Fourthly, based on the above research, the framework and model of interdisciplinary multi granularity knowledge representation are constructed to realize the interdisciplinary multi granularity knowledge representation of digital library knowledge resources. Finally, according to the knowledge representation framework and model, the knowledge of two articles from different disciplines are represented, which not only fully describes the knowledge content of each article but also reveals the interdisciplinary link between them. As a result, the validity of the proposed knowledge representation framework and model is verified. The case study indicates that the interdisciplinary multi granularity knowledge representation framework and model provided by this paper have the characteristics of multi granularity, interdisciplinary, multi angle, dynamic, semantic expression smooth and extensibility, which are of great significance and value to support the interdisciplinary knowledge organization. 3 figs. 5 tabs. 24 refs. |

在当今大科学时代,为支撑跨学科研究,数字图书馆的知识组织方法需要从基于文献、按学科的知识组织向基于知识内容的跨学科知识组织转变。知识表示作为知识组织的核心与基础,是解决数字图书馆跨学科知识组织的关键。本文首先对馆藏知识资源跨学科的共性与差异特征进行分析,为跨学科的知识表示提供理论支撑；而后,依据知识的抽象程度对馆藏知识进行多粒度划分,识别出知识表示的基本单位；接着,基于对以知识为单元的知识表示方法在跨学科知识表示方面的适用性分析,构建跨学科多粒度知识表示模型,实现馆藏知识资源的跨学科多粒度知识表示；最后,通过案例分析指出该知识表示模型具有多粒度、跨学科、多角度、动态性、语义自然和可扩展等特征,对于支撑数字图书馆跨学科知识组织具有参考价值。图3。表5。参考文献24。
