光觸媒文獻之書目計量學研究 Photocatalysis Literature Analysis: A Bibliometric Approach

Abstract

本研究從書目計量學角度探究光觸媒文獻發展狀況，研究樣本檢索自SCIE（Science Citation Index Expanded）資料庫，蒐集年代從1970至2003年，共34年得7,141筆資料。研究項目包括：一、文獻成長情形；二、文獻類型、出版國與語文分佈；三、機構生產力分析；四、布萊德福定律之驗證；五、核心期刊研究；六、期刊影響因素之探討。研究結果歸納如下：光觸媒文獻至2003年仍持續成長，其模式為指數成長；文獻類型以研究性質文章為主；英文是最主要的寫作語言；機構生產力以日本排名第一；利用布萊德福－齊夫定律求得15種核心期刊；以JCR（Journal Citation Reports）評鑑期刊影響力大小，其分佈與布萊德福分區相近。The purpose of this study is to explore the characteristics of photocatalysis literature based on the theoretical perspectives of the bibliometrics, such as literature growth, document type and language, author affiliation productivity and journal productivity. The distribution of journal articles and core journals were examined by Bradford’s law, Bradford-Zipf’s law and the impact factor of ISI’s Journal Citation Reports (JCR). A total of 7141 bibliographic records, from 1970 to 2003, were retrieved from Science Citation Index Expended (SCIE) database. The results of this study reveal that 1. the literature growth rate is in a steadily up-growing trend recently. Moreover, the overall growth is similar to exponential model; 2. research article is the major type of publication. Research and review papers account for 92.5% of total literature; 3. English is the most frequently used language and Japan is the most productive country; 4. zone analysis and graphical formulation from Bradford’s law of scattering are reexamined and it is found to be inapplicable to journal productivity distribution; 5. the Bradford’s law and Bradford-Zipf’s law are applied and identified 13 and 15 core journals, respectively; 6. based upon the impact factor from JCR, the average impact factor for journals of the first zone and second zone is higher than journals of the other zones.
