一种分析学科演化的模型及方法

Methodology of Modeling and Analyzing Disciplinary Evolution

学科概念知识图谱是判断学科发展演化的重要依据,也是构建智能导学系统的基础性工作。本文提出了一种基于概念的高精度层级结构模型,该模型通过抽取学科的知识体系中的基本概念,建立了一个学科知识体系数据库,使用自然语言处理和信息可视化等工具,描绘出该学科的演化发展脉络。为了验证模型和方法的有效性,我们选用了50多年来ACM/IEEE发布的计算机学科知识体系作为数据集进行分析,给出了6类学科知识图谱,这些图谱客观反映了计算机学科经历了知识领域体系重构和快速更新的发展历程。

The knowledge map of subject concept is fundamental for overviewing the evolution of discipline development,and also the ground work of designing intelligent adaptive learning system.In this paper,a high precision hierarchical structure model based on concept is proposed,which embarks from the domain basic concept in the subject knowledge system,and uses natural language processing techniques and data mining tools to calculate and mapping the pathway of the subject development.In order to verify the validity of our model and method,we use ACM/IEEE Curriculum as the data set to analyze,give 6 kinds of subject knowledge Atlas,which objectively reflects the development course of computer science which has undergone the reconstruction of knowledge domain system rapidly in past 50 years.
