Constructing conceptual trajectory maps to trace the development of research fields

摘要: This study proposes a new method to construct and trace the trajectory of conceptual development research field by combining main path analysis, citation text-mining techniques. Main used commonly most critical in network, helps describe developmental field. extends analysis applies techniques method, which reflects an academic more accurately than frequency, represents only articles examined. Articles can be merged based on similarity concepts, merging concepts history described precisely. The was applied "h-index" "text mining" fields. precision, recall, F-measures h-index were 0.738, 0.652, 0.658 those 0.501, 0.653, 0.551, respectively. Last, this not establishes map field, but also recommends keywords that are precise currently researchers. These could enable researchers gather related works quickly before.
