Knowledge Measurement In Domestic And Foreign Robotics

The creation of Knowmetrics is the evitable result of interaction between the science-technology knowledge system and the social needs.The robot is the aggregation of various kinds of science-technology knowledge.This paper comprehensively analyzes the discipline and the state of development of the science-technology knowledge system in the area of robots that have been studied at home and abroad in recent 10 years.The theoretical direction of this paper is the theories and methods of Knowmetrics.The carrier of knowledge is the published papers on periodical and patent literatures.The main data source is the information of publish papers included by Web of Science in robots,Derwent Innovations Index and Seven-country and Two-organization Patent Index Database.The particle size of knowledge consists of knowledge element, knowledge communities and knowledge network.Firstly,this paper analyzes the discipline and the state of development of the science-technology knowledge system in the area of robots that have been studied at home and abroad in recent 10 years.After that,taking robot~* as the key word,ARTICLE as the paper type,1999-2008 as the time span,the paper profoundly analyzes the phenomenon of cooperation between research institutes,covering 20,634 published papers on periodical,and then visualizes the knowledge distribution and knowledge frontiers in the area with the help of the visualization tool CiteSpaceⅡ.Then,the relationship between knowledge group in area of robot and the subject of knowledge is studied.The development and involvement of science knowledge are scientifically measured as a contrastive analysis.Secondly,taking the Derwent Innovation Index(DII) as the main data source,the CiteSpaceⅡas the visualization tool,this paper visualizes the distribution of technology knowledge frontier and scientifically measures the core technology knowledge and patent citation,covering 4,151 patent literatures.At the same time,the paper takes the patent literatures from the Seven-country and Two-organization Patent Index Database and analyzes the documentation synthetically and comparatively.As a result,a knowledge map of patent of invention of robot is drawn.
