关于Scopus与EI Compendex不得不说的事

　　关于Scopus与EI Compendex不得不说的事。EI2013刊源调整已经尘埃落定。部分被踢的EI源刊只被Scopus检索，到底什么是Scopus?已有相关帖子，但存在的成分，在此不得不正名了。
Scopus与EI Compendex到底有什么区别？其实EI官网就有答案

How do Scopus and Compendex differ?
Compendex is an abstract and index (A&I) database targeted specifically for research in
engineering and related disciplines. Its specialized content and subject-specific indexing
allows researchers to zero in on their precise engineering research topics. Engineering
Village search functionality leverages Compendex index data (controlled terms, classification
codes etc) to uncover the most relevant information and put results in context . Compendex
is indexed with subject specific controlled vocabulary, which comes from the Ei Thesaurus.
Compendex coverage includes:
 5.6K+ journals, trade magazines
 2500 conference proceedings
 650K records added annually
 Publications from more than 64 countries
 12 million+ records
 Coverage from 1970-present (from 1884 when supplemented with EI Backfile)
Scopus is an abstract and citation database that enables researchers to effectively uncover
published research, develop insights into connections between published works, and locate
collaborators and experts across multiple disciplines. Scopus search leverages citation
data (author/affiliation identifiers and citation analytics). Scopus cross-disciplinary coverage
includes:
 Over 16K journals from 4000 publishers
 520 Conference proceedings with serial character plus 6,000 one-off meetings
(details see in conference tab of Scopus title list at

 650 trade publications
 1.7mln records added annually
 36 million+ records (of which 18mln post-1995; 18mln 1823-1995)
Compendex and Scopus have nearly 100% overlap of source content. However, while
Scopus covers a broad range of disciplines, Compendex includes only those expertly
selected sources specific to engineering. In addition, Compendex on Engineering Village can
be searched alongside other popular resources such as Inspec, NTIS, Referex, Ei Patents,
and others.
Scopus records are linked via citation data and Compendex records are linked via controlled
vocabulary and classification codes, which come from the EI Thesaurus.
Because of these differences, even though source content overlaps these two
databases will provide two very different sets of results and very different records.

因此，可以回答几个问题：
1. Scopus是野鸡检索吗？当然不是！可以认为是艾斯维尔公司的力作。
2. Scopus与EI之间的关系类似于SSCI与SCI吗？当然更不是，可以认为EI是Scopus的子集，EI源刊99%被Scopus检索。二者的最大区别在于Scopus涵盖了更多的学科门类，而EI侧重于工程。
3. 为什么不少国家更多的承认Scopus? 因为从检索工具的角度，Scopus做的更完善。在很多国家，SCI也好，EI也好，Scopus也好，只是作为一种检索工具来使用，并不认为是文章身份的象征。如同google和baidu. 尽管google更有人气，被google检索到的信息，一定比百度检索到的信息更有身份吗？

不管怎样，希望在将来的中国，更多的利用这些检索工具做科研，而不是去纠结于“发了几篇被**检索了论文”？
===有问必答===
LZ是大师啊，阐述的很明白，长见识了
Scopus收录的期刊太多太多了，从某种程度上说，我觉得用EI和SCI是可以衡量文章身份的
就好象现在的高考，虽然负面声音也很大，其实还是最好的衡量办法了
----
正解。现在我所在的大学，都用scopus替换掉了web of science了。scopus前途巨大，科研好工具。

完全赞同，其实国外很多国家并不看重SCI,EI这些东西的，他们设计出这些东西的初衷只是提供一种检索工具。但是再好的政策制度到了中国都会变味儿，现在SCI,EI都已经成为了身份的象征，这在外国人看来，完全不可理喻。
当然他们也有评价好坏的指标，但是感觉他们更看重这篇文章的内容，而不是像我们纠结于这篇文章发表 在SCI还是EI期刊上。难道一篇好文章发表在SCI还是中文核心上，这篇文章的学术水平也就变化了吗？
----
学生要毕业，青教要职称、要项目、要绩效，
EI、SCI就是考核标准，这不以我们的意志为转移。
就像高考一样，也许有更好更公平的考核量化标准，但现在还没找到。
