Getting Started with the Semantic Web Using SPARQL with R

A new article on R Bloggers explains how to get “up and running on the Semantic Web” using SPARQL with R in under five minutes. The article states, “We’ll use data at the Data.gov endpoint for this example. Data.gov has a wide array of public data available, making this example generalizable to many other datasets. One of the key challenges of querying a Semantic Web resource is knowing what data is accessible. Sometimes the best way to find this out is to run a simple query with no filters that returns only a few results or to directly view the RDF. Fortunately, information on the data available via Data.gov has been cataloged on a wiki hosted by Rensselaer. We’ll use Dataset 1187 for this example. It’s simple and has interesting data – the total number of wildfires and acres burned per year, 1960-2008.” Read more

Machine Mediated Meaning for Semantic Interoperability

The Available definitions of meaning have limitations. A triadic definition is proposed to meet objectives AA and BB.

Meaning is the property of valid expression in Natural Language Text (NLT) along with the context, which is capable of generating “Predefined Responses (PreRes)” from a “Specified Class of Recipients (R)” and the “meaning of NLT for R is PreRes”.
