The Trend Change of Bitumen Research: A Text Mining Analysis (2000-2010)

摘要

In recent years, much research has been devoted to the Bitumen research; However, few have deployed the study of the research trend. In fact, grasping the research trend is imperative for enterprises and researchers. The study aims at analyzing the trend change of Bitumen research from 2000 to 2010. The contribution of the study includes the following two points. First, the study has found the shift of the Bitumen research from "distribution" and "sand" related issues to the focuses of "surface" and "polymer". Second, the study finds a new way of literature survey by using the text mining method in order to explore the trend change.
