human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent groups of papers sharing a common citing paper.

Details of the hypergraph:
Center node: "The Possible Contribution of AI to the Avoidance of Crises and Wars: Using CBR Methods"
  Abstract: This paper presents the application of Case-Based Reasoning methods to the KOSIMO data base of international conflicts. A Case-Based Reasoning tool - VIE-CBR has been deveolped and used for the classification of various outcome variables, like political, military, and territorial outcome, solution modalities, and conflict intensity. In addition, the case retrieval algorithms are presented as an interactive, user-modifiable tool for intelli gently searching the conflict data base for precedent cases.
