摘要
选择JCR收录的3种医学信息学核心期刊,调查分析近3年网络引文的数量、域名分布和著录格式等外部特征,并利用引文分析和文本处理工具MMTx对网络引文及其来源文献进行内部主题特征的挖掘分析,可为了解本学科领域网络资源利用状况提供参考,对精选专业核心信息资源有借鉴意义。
By selecting three core journals of medical infomatics in JCR,we studied the characteristics of quantity, domain distribution and bibliography format of web citations from 2004 to 2006.Using the citation analysis methods and MMTx program,we thematically analyzed the literatures with web citation as well as the citations themselves.It is useful to provide a support for understanding the state of web resources utilization and selecting carefully the core resources.
