摘要:

研究基于形式概念分析(FCA)的学科知识结构探测方法,提出基于FCA的学科知识结构的定义和表示模型,详细阐述基于FCA的学科知识结构的构建方法。以图书情报学为例,以SCI和SSCI收录的16种图书情报学期刊在2001-2013年间的数据为样本,对基于FCA的学科知识结构探测方法进行实证分析。研究探测到新世纪以来图书情报学的9个主要研究主题,并揭示每个研究主题的核心关键词和活跃作者。与传统的知识结构探测方法相比,基于FCA的方法不仅能有效、合理地描述复杂概念及其层次关系,还能客观地显示出聚类和关联特征。

Abstract:

As a relatively new mathematical theory, formal concept analysis (FCA) provides a new theoretic base for knowledge discovery and data mining. This paper studies the method for detecting knowledge structure by using formal concept analysis, and presents the definition, representation model, and construction method of knowledge structure based on FCA. By analyzing the data of 16 journals in Library and Information Science indexed in SCI or SSCI from 2000 to 2013, this paper explores knowledge structure of Library and Information Science during the new century. The research detects nine major research themes of Library and Information Science, and further identifies the core keywords and authors associated with each theme. Compared with traditional methods for discovering knowledge structure, formal concept analysis method is more objective and can present complex concepts and clear hierarchical layout for detected knowledge structure.

Key words: formal concept analysis, concept lattice, knowledge structure, library and information science
