This study presents a new method for visualizing knowledge domain evolution using cocitation networks. It helps identify key research papers by highlighting visually prominent nodes in a panoramic network view.

Area of Science:

  • Bibliometrics
  • Information Science
  • Theoretical Physics

Background:

  • Understanding the evolution of scientific fields is crucial.
  • Identifying seminal works and intellectual turning points is challenging.
  • Existing methods for analyzing knowledge domains can be complex.

Purpose of the Study:

  • To introduce a novel method for progressively visualizing the evolution of knowledge domain cocitation networks.
  • To identify intellectually significant articles and turning points within a field.
  • To simplify the cognitive load associated with analyzing complex research landscapes.

Main Methods:

  • Deriving a sequence of cocitation networks from time-sliced data.
  • Merging time-registered networks into a panoramic visualization.
