EI收录论文的识别

1、EI 收录论文的识别工程索引 (Engineering Index, Ei)数据库中被 Ei Compendex 收录与被 Ei Pageone 收录数据的区别和识辨钱佳平 * 马景娣(教育部科技查新中心浙江工作站)我们通常所称的工程索引 (Engineering Index, Ei) 数据库，目前主要有三个版本，即 “ Ei Compendex ”光盘数据库， “ Ei Compendex Web”数据库和 “ Engineering Village 2 ”。这三个版本中，其中的“ Ei Compendex ”光盘数据库，其内容与相应的国际联机数据库一致， 即为 Ei Compendex ；

2、而后二者( “ Ei Compendex Web ”和 “ Engineering Village 2 ”) 的内容则为 Ei Page One 。 Ei Page One 收录 5000 余种工程期刊和会议录，涵盖并扩充了仅 收录 2600 余种工程期刊和会议录的 Ei Compendex 数据库的内容。习惯上，我们将 Ei Compendex 收录数据称为“核心数据” ，而将 Ei Page One 收录数据称为“外围数据” 。在将 工程索引 (Engineering Index, Ei)数据库作为科学评价工具时， 这两类数据的价值是有区别的。由于不同版本的数据库其收录数据的著录和显示格式

3、不同， 给后二种数据库 (“ Ei Compendex Web ”和 “ Engineering Village 2”)中 Ei Compendex 收录数据和 Ei Page One 收录论文数据的区别和识辨造成了困难。 现将这二个数据库中 Ei Compendex 收录论文和 Ei Page One 收录论文的区别和识辨方式分别介绍说明如下：一、“ Ei Compendex Web ”中 Ei Compendex 收录论文和 Ei Page One 收录论文的区别在“ Ei Compendex Web ”中 ， Ei Compendex 收录论文的特征是：首先 其数据的著录格 式中一定包含

4、文摘( Abstract )项。而 Ei Page One 数据的著录格式中则可能没有文摘 ( Abstract )项；其次，也是最关键的一点是，前者含有 Ei 主题标识字段或赋有标题词。即 Ei Compendex 收录论文在 Ei tagged 格式中，含有 CL、CV 、FL、MH 等 Ei 主题标识字段，而 在 Abstract 格式中则含有标题词( subjects )项。现举例说明以下：下述 Ei tagged 格式中文献 1 为 Ei Compendex 收录，文献 2 为非 Ei Compendex 即属 Ei Page One 收录，两者区别为：文献 1 含 CL、CV 、F

5、L、MH 等 Ei 主题标识字段，文献 2 则无此项。1.ID 1425430AN 7108351IG 1003869CN ZDGXERTI Data fusion method for on-line performance calculation of turbogeneratorTR AXAU Chen, Jian-Hong; Li, Wei; Sheng, De-Ren; Ren, Hao-RenAF Zhejiang Univ.ACHangzhou 310027AY ChinaST Zhongguo Dianji Gongcheng Xuebao/Proceedings ofthe
