有两种不同的方法来处理双模数据。第一种方法是将数据投影到单模，然后使用标准单模技术（也称为转换方法）分析投影后的网络。第二种方法是将方法和概念扩展到双模情况，并将两种模式联合考虑直接分析网络。由于假设转换方法会丢失重要的结构信息，近年来直接方法一直是首选的方法。在这里，我们认为，如果在任何分析中同时使用这两种预测，情况并非如此。我们以核心/外围、结构等效性和中心性为例说明这种方法是如何工作的。(C) 2012 Elsevier B.V.版权所有
There have been two distinct approaches to two-mode data. The first approach is to project the data to one-mode and then analyze the projected network using standard single-mode techniques, also called the conversion method. The second approach has been to extend methods and concepts to the two-mode case and analyze the network directly with the two modes considered jointly. The direct approach in recent years has been the preferred method since it is assumed that the conversion method loses important structural information. Here we argue that this is not the case, provided both projections are used together in any analysis. We illustrate how this approach works using core/periphery, structural equivalence and centrality as examples. (C) 2012 Elsevier B.V. All rights reserved.
