文章发表时间对生物医学文献知识发现的影响

摘要

The effect of paper publication time on knowledge discovery in biomedical literature was studied by analyzing the role of time factor in indirect link mining and tested using the PubMed-covered data set,which showed that recently published papers played a better role than early published papers in knowledge discovery,indicating that the time factor plays a certain role in knowledge discovery in biomedical literature and can thus improve the efficiency of knowledge discovery in biomedical literature.%通过分析时间因素在间接关联挖掘中的作用,探讨文章发表时间对生物医学文献知识发现的影响.利用来自PubMed的数据集进行测试分析,发现在知识发现过程中近期文献比早期文献获得新关联的效果好,表明时间因素对生物医学文献知识发现具有一定作用,即在间接关联的挖掘过程中考虑时间因素,可以提升生物医学文献知识发现工作的效率.
