human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "almost shortest paths and pram distance oracles in weighted graphs"):
  Abstract: Let $G=(V,E)$ be a weighted undirected graph with $n$ vertices and $m$ edges, and fix a set of $s$ sources $S\subseteq V$. For any pair $u,v\in V$, let $W(u,v)$ denote the weight of the heaviest edge on the $u$ to $v$ shortest path. For any constant $0 0$, we preprocess a given weighted graph in poly-logarithmic time and near linear work, and store a data structure of size $O(n^{1+\delta})$. Given any query $u\in V$, we return a $(1+\epsilon,\beta(\cdot,\cdot))$-approximation to all distances $u\times V$ in $O_\delta(1)$ time, where $\beta(u,v)=O_\delta(W(u,v))$. Moreover, the dependence of both $\beta$ and the query time on $\delta$ can be made $\text{poly}(1/\delta)$, by increasing the multiplicative stretch (to some constant larger than 9). Our algorithms are based on new constructions of spanners, emulators and hopsets for weighted graphs. We devise a $(1+\epsilon,\beta(\cdot,\cdot))$-spanner for weighted graphs of size $O(n^{1+1/t}+\log t\cdot n)$ and $\beta(u,v)=W(u,v)\cdot \left(\frac{\log t}{\epsilon}\right)^{O(\log t)}$. We can have an improved $\beta=W(u,v)\cdot t^{O(1)}$ at the cost of increasing the multiplicative stretch to a constant larger than 3. In addition, we devise a $(c,t^{O(1)})$-hopset of size $O(n^{1+1/t}+\log t\cdot n)$ for any constant $c>3$.
