Applications

• illumin8 by Elsevier a research tool that provides innovation and R&D professionals with actionable insights from scientific, patent, and news content.

Open Data Sources

• DBpedia the community effort to extract structured information from Wikipedia and to make this information available on the Web.
• FrameNet is building a lexical database of English that is both human- and machine-readable, based on annotating examples of how words are used in actual texts. FrameNet is based on a theory of meaning called Frame Semantics, deriving from the work of Charles J. Fillmore and colleagues.
• UK Discovery 10 openly licensed datasets are part of the Discovery Developer Competition
• CKAN, the Data Hub the Comprehensive Knowledge Archive Network, a registry of open knowledge packages and projects (and a few closed ones).
• World Bank data more than 3,000 indicators for countries with some data series dating back 50 years.
• Music Brainz an open music encyclopedia that collects, and makes available to the public, music metadata.

Ontologies

By Author

• Nancy Ide, Vassar
• Barry Smith, National Center for Ontology Research

Temporal Ontologies

Representing dynamic events, historic events, anything where information in the ontology must be temporally contextualized.

• Historical Ontologies Nancy Ide and David Woolner In Ahmad, K, Brewster, C., and Stevenson, M. (eds.), Words and Intelligence II: Essays in Honor of Yorick Wilks, Springer, 137-152.

Spatial Ontologies

• SNAP and SPAN: towards Dynamic Spatial Ontology Pierre Grenon and Barry Smith, Spatial Cognition and Computation, 4: 1 (March 2004), 69–103

RDF

• rdfabout.com Joshua Tauberer's collection of useful introductory information about RDF and the Semantic Web. Excellent intro material, as well as some good data sets. Some good deep links:
  • Quick Intro to RDF 5 very readable pages.
  • What is RDF and what is it good for adds more details.
• W3C RDF Primer basic knowledge required to effectively use RDF: XML syntax, how to define RDF vocabularies, overview of some deployed RDF applications.
• Turtle - Terse RDF Triple Language a textual syntax that allows RDF graphs to be completely written in a compact and natural text form, with abbreviations for common usage patterns and datatypes.

N3

• Primer: Getting into RDF & Semantic Web using N3 how to get started using a simplified teaching language -- Notation 3 or N3.
• Notation 3 or N3 specification for N3 a language which is a compact and readable alternative to RDF's XML syntax, but also is extended to allow greater expressiveness.

Semantic Web

• SHOE - Simple HTML Ontology Extensions Papers by Jeff Heflin, James Hendler, and Sean Luke
• SemanticWeb.com Answers Active Q/A forum about the Semantic Web.
• Sindice, the Semantic Web Index a platform to build applications on top of a huge indexed set of Semantic Web data.

Triple Stores

• LargeTriplesStore list on W3C wiki a list of (very) large triple stores along with links.

Tools

• GATE General Architecture for Text Engineering
