The paper suggests newly conceptualized information retrieval system on the notion of citation analysis. The paper also criticizes the traditional information retrieval techniques using Boolean logic. The underlying assumption of this paper is that any pair of papers cited by one paper could be strongly related each other in meaning (Co-citation Analysis). And also any two papers to share same references could be similar each other (Bibliographic Coupling), By using graph algorithm, the networks of two kinds of the papers (the citing group, the cited group) is made in the fields of the genetics and the information and library science. The results say that the maps or networks for cited and citing groups can be useful when applied to the paper set made by the broad searching by subjects or keywords.
