Abstract:
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.
Keywords:Knowledge discovery   Literature mining   Publication time   Complicated network
