\begin{questions}
    \item \label{rq:events} How should event-based links, which may re-occur over time, be dealt with in order to accurately predict future links?
    \item \label{rq:availability} To what extent does the availability of temporal information improve the performance of link prediction approaches?
    \item \label{rq:structure} What is the relationship between structural network properties of temporal networks and the performance of the link prediction model?
    \item \label{rq:node-or-edge} How can we use link prediction to understand whether the temporal aspect is governed by the temporal activity of nodes, or by that of the edges?
\end{questions}
% In document
As part of~\ref{rq:node-or-edge}, we use feature set~\ref{f:node} to capture the node activity.


% And feature sets, indicated with roman letters.
