Semantic Web
The Semantic Web is a collaborative movement led by the World Wide Web Consortium that promotes common formats for data on the World Wide Web. By encouraging the inclusion of semantic content in web pages, the Semantic Web aims at converting the current web of unstructured documents into a "web of...

 publishing refers to publishing information on the web as documents accompanied by semantic markup. Semantic publication provides a way for computers to understand the structure and even the meaning of the published information, making information search and data integration
Data integration
Data integration involves combining data residing in different sources and providing users with a unified view of these data.This process becomes significant in a variety of situations, which include both commercial and scientific domains...

 more efficient.

Although semantic publishing is not specific to the Web, it has been driven by the rising of the semantic web. In the semantic web, published information is accompanied by metadata describing the information, providing a "semantic" context.

Although semantic publishing has the potential to change the face of web publishing, acceptance depends on the emergence of compelling applications. Web sites can already be built with all contents in both HTML

Semantic publishing has the potential to revolutionize scientific publishing
Academic publishing
Academic publishing describes the subfield of publishing which distributes academic research and scholarship. Most academic work is published in journal article, book or thesis form. The part of academic written output that is not formally published but merely printed up or posted is often called...

Sir Timothy John "Tim" Berners-Lee, , also known as "TimBL", is a British computer scientist, MIT professor and the inventor of the World Wide Web...

 predicted in 2001 that the semantic web “will likely profoundly change the very nature of how scientific knowledge is produced and shared, in ways that we can now barely imagine”. Revisiting the semantic web in 2006, he and his colleagues believed the semantic web “could bring about a revolution in how, for example, scientific content is managed throughout its life cycle”. Researchers could directly self-publish their experiment data in "semantic" format on the web. Semantic search engines could then make these data widely available. The W3C interest group in healthcare and life sciences is exploring this idea.

Two approaches

  • Publish information as data objects using semantic web languages like RDF
    Resource Description Framework
    The Resource Description Framework is a family of World Wide Web Consortium specifications originally designed as a metadata data model...

     and OWL
    Web Ontology Language
    The Web Ontology Language is a family of knowledge representation languages for authoring ontologies.The languages are characterised by formal semantics and RDF/XML-based serializations for the Semantic Web...

    . Ontology is usually developed for a specific information domain, which can formally represent the data in its domain. Semantic publishing of more general information like product information, news, and job openings uses so-called shallow ontology. The SWEO Linking Open Data Project maintains a list of data sources that follow this approach as well as a list of Semantic Publishing Tools.
  • Embed formal metadata in documents using new markup languages like RDFa
