Based on current theories and practices of disjoint literature-based discovery,this paper explores the third-order disjoint literature-based discovery method.A framework and process of the thirdorder disjoint literature-based discovery method are proposed in this paper.Furthermore,a preliminary experiment is carried out in the field of laser display and shows a potential relationship from actual applications and technology system to theory is found.The third-order disjoint literature-based discovery can be goal and problem-oriented,to provide services for research activities.
