Path-Oriented Keyword Search Query over RDF

  • Chapter
  • First Online:
Semantic Search over the Web

Part of the book series: Data-Centric Systems and Applications ((DCSA))

Abstract

We are witnessing a smooth evolution of the Web from a worldwide information space of linked documents to a global knowledge base, where resources are identified by means of uniform resource identifiers (URIs, essentially string identifiers) and are semantically described and correlated through resource description framework (RDF, a metadata data model) statements.

Notes

  1. 1.

    We do not explore further the notion of semantic query expansion and refer here to standard IR techniques.

  2. 2.

    The geometric mean of a dataset \(\{{a}_{1},{a}_{2},\ldots,{a}_{n}\}\)is given by \(\root{n}\of{{a}_{1} \cdot {a}_{2}\cdots {a}_{n}}\).
