调查了自动化和计算机技术类核心期刊实现开放获取的现状,并通过分析网站下载量、CNKI下载量及其与引用次数之间的相关性考察了OA期刊网站的传播效果,结果显示:(1)该学科核心期刊有71%实现了不同程度的全文开放;(2)OA期刊实时开放的比例优于商业数据库CNKI和维普,但过刊回溯情况不及商业数据库。(3)绝大多数OA期刊的网站下载量已高出其CNKI下载量,成为科研人员获取信息的重要渠道。从整体上看,网站下载与引用存在相关关系;具体到各期刊时,大半期刊的网站下载与引用不相关,期刊网站的网络知名度和网络可见性之不足、内容开放的滞后性、部分网站可能存在的异常下载是造成这种背离的可能原因。
Investigated the status quo of open access to core periodicals in automation and computer technology and investigated the spread of OA periodical websites by analyzing the correlation between website downloads, CNKI downloads and citations, and the results showed that: (1) 71% of the core journals of this discipline have achieved full-text openness in varying degrees; (2) The proportion of open-ended OA journals in real time is superior to that of commercial databases CNKI and VIP, but the backdated backlog is not as good as that of commercial databases. (3) The vast majority of OA journals have downloaded their CNKI downloads much more than their CNKI downloads, making them an important channel for researchers to obtain information. As a whole, there is a correlation between downloading and quoting of websites. When downloading to most journals, the download of most journals is irrelevant to the quotation, the lack of visibility and network visibility of journals, the lag of content opening, and some websites may Existence of abnormal download is the possible cause of this departure.
