中文摘要：
进入新世纪以来，科学知识图谱与知识可视化得到迅速的发展，已成为科学计量学和情报计量学的主流领域。文章借助科学知识图谱的方式和实例，来展示和分析科学知识图谱的基本概念、发展历程、前沿领域、主要方法和类型，以及在科技情报领域中的广泛应用。从知识图谱研究文献的共引知识图谱，发现了知识图谱和知识地图的差异，知识图谱研究的前沿动向及其知识基础。从科技情报数据的共引知识图谱，展现了知识图谱方法在探测学科前沿、科学发现、科学合作和科技战略诸方面的引领作用。知识图谱不仅创新了分析科技情报的模式，而且改变了人们观察世界的方式。
英文摘要：
In the new century, scientific knowledge mapping and knowledge visualization has developed rapidly and become the mainstream of scientometrics and informetrics. In this paper, the authors employed the methods and examples, to display and analyze the basic concepts, evolving process, frontier field, main methods and forms of scientific knowledge mapping. From the co-citation maps of knowledge mapping literatures, the authors fotmd the difference of knowledge mapping and knowledge map, the frontier directions and its intellectual base. And fi＇om the co-citation maps of scientific and technological information data, the authors displayed the leading role of knowledge mapping in detecting research frontier, scientific discovery, scientific cooperation, science ＆ technology strategy, etc. Knowledge mapping not only innovated the pattems of researchers to analyze scientific and technological information, but also changed the ways of people to observe the world.
