is obtained by keyword analysis for different time periods and research field maps. The integrated method is applied on etching technology which is a material processing technology particularly important for semiconductor industry. On the basis of the results obtained in the practice of etching technology, six different
To hold the developing trend of the virtual reality technology, and reflect major nations' advances and influences on the state of the art, articles indexed by SCI-EXPANDED from 1997-2009 were studied by using of bibliometric analysis. The only keyword is virtual reality, and 2921 articles were analyzed. Some results
over the past 20 years and the annual paper production in 2007 was about three times that in 1999. The analytical results eventually lead to several key findings. Several author keywords became the focus in the last few years, and might be a new research direction in the future. There are clear distinctions among author
. The research covers the following areas. 1. Statistics of keywords used in the 1845 documents. 2. Statistics of publication years of documents. 3. Statistics on the numbers of documents written by different authors. 4. Statistics of documents type. The aim is to provide data for scholars on the study of precision
A bibliometric analysis was applied in this work to compare SCI and EI papers on GIS. The published output analysis showed that GIS research has steadily increased in both databases of SCI and EI. The different characteristics of SCI and EI databases in journals and keywords were also discovered. It showed that we
