機器人文獻之合著網絡及熱門主題分析 Analysis of the Co-authorship Network and Hot Topics in the Robotics Literature

本研究主要探討機器人文獻之合著情況及高被引文獻之熱門研究主題，以科學引文索引擴充版（SCIE）資料庫中14種機器人學核心期刊文獻為研究資料來源，樣本資料共計9,571篇研究論文，分布於1983-2009年間。研究分析結果顯示，機器人學每年研究論文篇數由96篇成長至746篇，整體之合著率為82.71%，以2至4位作者為最主要的合著型態。在國家層次方面，整體跨國合著率為11.98%，美國是跨國合著篇數最高且最具資源控制能力之國家，但其跨國合著率（22.79%）不及瑞士跨國合著率（48.51%）。在機構層次方面，整體跨機構合著率為29.24%，美國卡內基美隆大學是跨機構合著篇數最高之機構，然而，日本國際電氣通信基礎技術研究所的跨機構合著率達85.71%，高於美國任一機構。另外，美國麻省理工學院為最具有資源控制能力之機構。高被引文獻之關鍵字分析結果呈現六大研究主題，包括無固定路線之機器人、智慧型機器人、視覺機器人、固定路線或固定點之移動機器人、時域機器人、夾爪機器人。 The purpose of this study is to explore the co-authorship and the hot topic from the most highly cited articles of robots literature. The research targets are 14 journals of robotics from the Science Citation Index Expanded (SCIE) database. A total of 9,571 articles were collected from 1983 to 2009. The conclusions are as follows. The total number of articles from robots literature increased gradually from 96 to 746 each year. The percentage of co-authored articles was 83% and the most frequent numbers of authors per article ranged from 2 to 4. At the national level, the multinational collaboration accounted for 12% of the co-authored articles. The U.S. owned the largest number of multinational collaboration articles and had the highest value of the three chief kinds of centrality measures, which indicated that the U.S. played the key role in controlling resources. However, the portion of multinational collaboration among the co-authored articles for the U.S (22.79%) was lower than that for Switzerland (48.51%). At the institutional level, about 29% of publications were the result of author collaboration in different institutions. Carnegie Mellon University owned the largest number of inter-institutional collaboration articles. Nevertheless, approximately 86% of the co-authored articles published by Advanced Telecommunications Research Institute International (AIR) in Japan were inter-institutional, which is higher than the percentage of inter-institutional collaboration articles published by any American institutions. In addition, Massachusetts Institute of Technology played the key role in controlling resources. The result of keywords analysis of the most highly cited articles shows 6 major research categories including flexible-path of robot, intelligent robot, vision robot, fixed path or point of mobile robot, time-domain robot, and end-effect robot.
