基于web of science 分类的工程学科交叉性研究

Research on Interdisciplinary phenomenon of engineering discipline based on Web of Science classification

摘要:

工程学科在Web of Science分类中包括18个子类,各类中期刊与Web of Science其他类别存在较多交叉现象。本文提出学科交叉向量空间模型表示方法,计算出学科间的相关性,对学科间的交叉程度进行定量分析,进而揭示工程学科的交叉性规律。研究发现：(1)学科交叉已是学科发展中的一种普遍现象；(2)工程学科内部子类之间虽然存在交叉,但交叉性不明显,仅机械工程、土木工程与其他学科交叉数量达到5个以上；(3)工程学科与能源燃料、电信、材料科学等学科具有较强交叉性；(4)与工程学科存在紧密联系的学科群主要有7个,分别为环境科学、细胞生物学、心理学、计算机科学、应用物理、数学应用和公众健康学科群。研究结果可为促进工程学科的发展以及推动科研整体水平提升提供科学建议。

Abstract:

The engineering discipline includes 18 subclasses in the Web of Science classification, and there are many intersecting phenomena in various journals and other categories of Web of Science. In this paper, vector space model representation of interdisciplinary was proposed to calculate the correlation between disciplines, carries on the quantitative analyze the degree of cross-disciplines, and reveal the law of engineering cross discipline. It is found that (1) cross discipline is a common phenomenon in the development of disciplines.(2) Although there is a crossover between the different subclasses of engineering disciplines, the intersections are not obvious, and only mechanical engineering, civil engineering cross more than 5 disciplines.(3) Engineering disciplines have strong intersections with energy fuels, telecommunications, materials science and other disciplines;(4) There are seven main disciplinary clusters closely related to engineering disciplines, respectively, Environmental Science, Cell Biology, Psychology, Computer Science, Applied Physics, Mathematics Application and Public Health Discipline.
