The rise of mapping knowledge domain

Mapping knowledge domain is a kind of graph showing the relationship between evolution and structure for science knowledge. Its rise shows that ,one hand, the research direction for the scientometrics revealing the law of sciences knowledge and science activity is turning from mathematics expression to graph expression, on the other hand, the display for knowledge map is turning from geography distribution to knowledge structure relationship and evolution rule. Basing on the basic concepts of knowledge map, this paper introduce the lasted improvement in mapping knowledge domain on three aspects, which are Data basesdata formataccess, Data analysis algorithms,Visualizationinteractive design and scientometrics. Its Promising applications showing that mapping knowledge domain is an effective knowledge management tool to sciencetechnology research and enterprise technology innovation.
