文章旨在改进共词分析方法,提出基于语义距离的共词分析法,通过领域本体进行概念映射,并基于领域本体计算语义距离,将语义距离与映射后的概念矩阵进行融合,从而改进共词分析方法。通过方法原理探讨与实证分析表明,基于语义距离的共词分析法,在矩阵维度和聚类效果维度上,均有所改善,并能够从内容上更好地揭示领域的研究现状。 The article aims to improve the method of co-word analysis, propose a co-word analysis method based on semantic distance, make conceptual mapping through domain ontology and calculate the semantic distance based on domain ontology, and then integrate the semantic distance with the mapped concept matrix to improve co-word Analytical method. Through the discussion of methodology and empirical analysis, it shows that the co-word analysis based on semantic distance improves both in matrix dimension and clustering effect dimension, and can better reveal the research status in the field from content.
