\caption{Development of the perception regarding the argument relevance induced
by PageRank regarding all possible aggregations. CPR, NetworkX and NetworkX
using Scipy were plotted against by Wachsmuth et al. the result obtained for different $\alpha$ values, which regulates the influence of linking the arguments.}
\caption{Direct comparison of the different PageRank against the approach of \cite{wachsmuth:2017a}.}
\caption{Comparison of the approaches of \cite{wachsmuth:2017a} (1-6) with those used in this study (7-15). For each aggregation (a-d) the average agreement $\tau$ and the cases in which the respective approach performed best or worst over the 32 conclusions of the 110 arguments are given. (e) shows the best results of an aggregation.}
