空间科学动态演化模型

A model for dynamical evolution of science in space

Jan Moritz Joseph, Jens Christian Claussen

摘要:

科学的拓扑空间是如何产生的?受科学地图概念的启发,即将科学主题映射到科学空间,我们问作者合作和发表论文的动态过程可以产生哪些拓扑结构。我们提出了一个动态的过程中,论文以及新的群体接收嵌入在二维欧几里得空间的主题位置。新论文的确切位置取决于各自作者以前的主题,并在周围的邻居中随机选择,包括新颖性和跨学科性。根据参数的不同,空间结构类似于一个简单的高斯分布,或观察到空间集群的副主题。我们量化的空间结构的时间演化,并讨论了不均匀性的影响。

英文摘要:

How does the topological space of science emerge? Inspired by the concept of maps of science, i.e. mapping scientific topics to a scientific space, we ask which topological structure a dynamical process of authors collaborating and publishing papers can generate. We propose a dynamical process where papers as well as new groups receive topical positions embedded in a two-dimensional euclidean space. The precise position of new papers depends on previous topics of the respective authors and is chosen randomly in a surrounding neighborhood including novelty and interdisciplinarity. Depending on parameters, the spatial structure resembles a simple Gaussian distribution, or spatial clusters of side-topics are observed. We quantify the time-evolution of the spatial structure and discuss the influence of inhomogenities.
