In the process of science and technology thesis writing and dissertation, to understand the current domestic and foreign research status and determine the research direction, we need to search the thesis database. As the saying goes, a good start is half the success. If the right database is selected during retrieval and the right retrieval technology is used, the future research work may take less detours. This article only discusses the retrieval of papers in computer-related fields.
first, is the choice of databases. Although the level of foreign research in computer science is more advanced than that in China, I feel that for a new field that is unknown to me, you can still learn a lot through searching domestic journals, Shuo and doctoral thesis. So here we will first introduce several domestic databases:
- chinnet http://www.cnki.net/including the full text of Chinese documents, doctoral thesis, domestic journal full text and other databases, PDF file quality is good, much clearer than VIPP, website content is rich, you can find some valuable things through careful browsing. It is said to be a daily update.
- VIP http://www.cqvip.com/China Journal network, general domestic journals of articles can be downloaded here. In the past, I downloaded it here. Later I found that the Chinese net is not very good, mainly because the downloaded PDF is not clear. However, Vipe provides essay modification and translation services. If you have money or are too reluctant to write English, you can try it. The update speed is okay, as if it was a half-month update.
- Wanfang data http://www.wanfangdata.com.cn/Includes dissertation, conference papers, scientific and technological achievements, patents and Chinese and foreign standards. Listen more and use less. One of the most inconvenient aspects of my personal experience is that I cannot download the full text at a time. If I want to download the full text, I have to save it on one page, which is very painful. If you want to download a degree thesis, you can download it directly from chinnet.
experiences: CNKI> VIP> Wanfang data :)
next, let's talk about foreign databases. First, we will introduce the three major indexes: SCI (Scientific Citation Index), EI (engineering index), and ISTP (Scientific Conference record index ). They are the world's famous three scientific literature retrieval systems. Among them, SCI and ISTP are all products under the Information Sciences Institute.
- SCI http://portal.isiknowledge.com/Science Citation Index expanded in the web of science in the ISI Web of knowledge. The most powerful sensory function provides a wide range of online analysis methods to sort retrieved documents by different criteria, you can easily understand important articles, important institutions, and important countries in a certain field. In addition, the endnote web tool provided by SCI can save online search articles to your personal endnote Web account, and the plug-in can be used to conveniently manage references in writing. In addition, endnote
The Web also supports file and sharing among multiple users, which is very useful for collaborative research.
- EI (engineeringindex) http://www.engineeringvillage2.org/is a non-full text index, only including abstract, divided into core and non-core, the core refers to the EI compendex database.
- ISTP (index to scientific & technicalproceedings) is actually ISI proceedings.
