3.3.5 由学科同被引构造知识图谱

学科(专业)同被引是以学科专业为单位来统计分析,如果属于两个学科的文献被别的学科的文献同时引用,则称那两个学科同被引,并以引用它们的文献数量的多少测度这两个学科间的同被引强度。

很明显,学科同被引可以使外部无联系的学科专业客观地联系起来,揭示了学科之间的相互交叉和渗透的错综复杂的结构关系。其应用大致有:

(1)了解和研究学科专业间的交叉和依赖关系,为科学学的研究提供依据。

如果C,D两学科(专业)被A学科同时引用,那么,A,C,D三个学科(专业)之间就呈现了一个网络关系,这个网络关系能揭示这三个学科(专业)之间的相互交叉和依赖关系。

(2)了解和研究学科(专业)间的分划、渗透关系。

在不同时期内不断跟踪统计分析学科(专业)的同被引关系网络,从同被引的学科在数量上的增加或减少可以揭示学科或专业的渗透或分划趋势。如果同被引的学科(专业)增加了,则认为有渗透趋势,相反则有划分趋势。

(3)揭示整个科学体系中各学科专业之间的错综复杂的关系。

具有同被引关系的学科还可以与别的学科有同被引关系,同时又可能单独地引用别的学科专业的内容,这样形成了一个错综复杂的网络,这个网络在一定程度上代表了整个科学体系中各学科专业之间的相互依赖关系。不断跟踪这个学科之间的关系网络在结构上的变迁,能够跟踪整个科学体系(包括自然科学和社会科学)结构随时间变化而变迁的状态,这种分析方法为科学学、史学、预测学的研究提供了新的分析途径。
