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 "verification and validation of semantic annotations"):
  Abstract: In this paper, we propose a framework to perform verification and validation of semantically annotated data. The annotations, extracted from websites, are verified against the this http URL vocabulary and Domain Specifications to ensure the syntactic correctness and completeness of the annotations. The Domain Specifications allow checking the compliance of annotations against corresponding domain-specific constraints. The validation mechanism will detect errors and inconsistencies between the content of the analyzed this http URL annotations and the content of the web pages where the annotations were found.

  Member "heuristics for publishing dynamic content as structured data with schema org":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "building an ecosystem for the tyrolean tourism knowledge graph")
  Member "complete semantics to empower touristic service providers":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "a formal approach for customization of schema org based on shacl")
