+			\item PageRank by \cite{PageRank1999} was originally used to evaluate relevant websites via their links
+			\item Websites can be replaced by arguments
+			\item Linking results due to the reuse of conclusions and premises
+			\item In this work it was used:
+			\begin{itemize}
+				\item Custom-made PageRank
+				\item NetworkX PageRank
+				\item NetworkX-Scipy PageRank

+	\begin{itemize}
+		\item As knowledge based method $Sim(T_1, T_2)$ of \cite{Mihalcea2006similarity} was used
+		\item $Sim(T_1, T_2)$ determines the semantic similarity of $T_1,T_2$ by mutually picking up highly similar concepts
+		\item The concepts were determined via WordNet
+		\item For $maxSim$ the $CoSim$ of \cite{Wu1994distance} was used
