In the previous chapter, we thoroughly discussed the trust propagation problem. However, besides propagation, a trust metric must also include an aggregation strategy. After all, in large networks it will often be the case that not one, but several paths lead to the user for whom we want to obtain a trust estimate. When this is the case, the trust estimates that are generated through the different propagation paths must be combined into one aggregated estimation; see for instance the situation depicted in Fig. 4.1.
