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: "path outlines browsing path based summaries of linked open datasets"
  Abstract: The Semantic Web is made of structured sources of information, such as DBpedia or GeoNames, also known as Linked Data (LD).#R##N#They can be linked and queried together. The information they contain is atomized into triples, each triple being a simple statement composed of#R##N#a subject, a predicate and an object. Triples can be combined to form higher level statements following information needs. This granularity makes#R##N#it difficult to produce overviews of the content. We introduce the concept of path-based summaries, which carries a higher level of semantics for#R##N#data producers, and the tool Path Outlines to support LD producers in browsing path-based summaries of their datasets. We present its interface#R##N#based on the broken (out)lines layout algorithm and the path browser visualisation. We report a characterisation of LD producers’ needs, and#R##N#show that our approach, reifying path outlines, was informed by this observation. We compare Path Outlines with the current baseline technique#R##N#(Virtuoso SPARQL query editor) in an experiment with 36 participants. We show that participants prefer Path Outlines, find it easier and more#R##N#comfortable to use, and that it is faster and leads to better task completion and less errors.
