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 "in depth benchmarking of graph database systems with the linked data benchmark council ldbc social network benchmark snb"):
  Abstract: In this study, we present the first results of a complete implementation of the LDBC SNB benchmark -- interactive short, interactive complex, and business intelligence -- in two native graph database systems---Neo4j and TigerGraph. In addition to thoroughly evaluating the performance of all of the 46 queries in the benchmark on four scale factors -- SF-1, SF-10, SF-100, and SF-1000 -- and three computing architectures -- on premise and in the cloud -- we also measure the bulk loading time and storage size. Our results show that TigerGraph is consistently outperforming Neo4j on the majority of the queries---by two or more orders of magnitude (100X factor) on certain interactive complex and business intelligence queries. The gap increases with the size of the data since only TigerGraph is able to scale to SF-1000---Neo4j finishes only 12 of the 25 business intelligence queries in reasonable time. Nonetheless, Neo4j is generally faster at bulk loading graph data up to SF-100. A key to our study is the active involvement of the vendors in the tuning of their platforms. In order to encourage reproducibility, we make all the code, scripts, and configuration parameters publicly available online.
