Extraction of key literature based on PageRank algorithm considering variance values of cited literatures as weighting

Abstract

Even though Citation Map has been in the mainstream of recent study trend in a field of academic landscape achieving the stage of automated clustering, the reality is that experts manually analyze semantic attachment about what kind of group each cluster is. Therefore, we try to achieve an automated extraction of key literature of each cluster in the report, by setting automated interpretation of each cluster as the final purpose of the study.
