我从cnki上下载了RefWork格式的txt文本,然后用citespace自带转换器转换后导入出现了
“citespace found no valid items to display.
1. Make sure that your data files indeed include relevant information, such as references. For example, Pubmed records do not provide cited references.
2. Try again with lower thresholds.”
陈老师,我的问题和【534】是一样的,这个是控制台的内容:
CiteSpace(3508): Unable to parse May 1, 2014

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
关于德温特专利分析,没能找到citespace分析结果作为参考,比较迷茫。
陈老师我在用3.7.R7进行德温特数据转换时也遇到了“with the current setting , citespace will make a partial conversion by assigning the filing date year 1000 to all cited patents”,然后转换一直处于假死状态。下面是Java控制台的提示:
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
