human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "crowdsource automated inference of high level malware functionality from low level symbols using a crowd trained machine learning model"
  Abstract: In this paper we introduce CrowdSource, a statistical natural language processing system designed to make rapid inferences about malware functionality based on printable character strings extracted from malware binaries. CrowdSource "learns" a mapping between low-level language and high-level software functionality by leveraging millions of web technical documents from StackExchange, a popular network of technical question and answer sites, using this mapping to infer malware capabilities. This paper describes our approach and provides an evaluation of its accuracy and performance, demonstrating that it can detect at least 14 high-level malware capabilities in unpacked malware binaries with an average per-capability f-score of 0.86 and at a rate of tens of thousands of binaries per day on commodity hardware.
