Abstract
"Complex network theory" attracts much attention for researchers. It may be influencing in various fields of the real world including business and human relations. But we cannot build the complete network even if we extract the structure of human network. It is because a real network has a character called the incompleteness. In this study, we pay our attention to the connection of the person, and having defined the incompleteness of the human network. And we suggest possibility of drawing the complete-network from a incomplete human network. If it is possible, we think about what kind of methodology exists.
