公认的协作网络模型是超图模型。尽管如此，当涉及到可视化时，超图被转换为简单的图。通常，变换是通过超边的集团扩展来进行的，从而导致用户的信息丢失，并且由于所表示的边数较多而人为地产生更复杂的图形。节点外表示在超图的可视化和信息检索方面提供了实质性的改进。本文的目的是定性和定量地展示节点外表示如何在不丢失信息的情况下改善超图的可视化。
The acknowledged model for networks of collaborations is the hypergraph model. Nonetheless when it comes to be visualized hypergraphs are transformed into simple graphs. Very often, the transformation is made by clique expansion of the hyperedges resulting in a loss of information for the user and in artificially more complex graphs due to the high number of edges represented. The extra-node representation gives substantial improvement in the visualisation of hypergraphs and in the retrieval of information. This paper aims at showing qualitatively and quantitatively how the extra-node representation can improve the visualisation of hypergraphs without loss of information.
