Tools are major enablers of Linked Science. One crucial aspect is how to access and analyze data, and especially how to get only that part of data which is of interest for a given research question. Linked Data solves the access part, and SPARQL allows to query only a subset of the data. For statistical computing there are tools like R. how to access and query Linked Spatiotemporal Data of the deforestation statistics related to the Brazilian Amazon Rainforest, andhow to analyze it within R (which is a free software environment for statistical computing).
SPARQL Package for R LinkedScience.org | interconnecting scientific assets! SPARQL Package is a function for R statistical software to enable to analyze Linked Data. Authors: Willem Robert van Hage and Tomi Kauppinen, with contributions from Christopher Davis. How to get started: Short technical description: SPARQL Package enables to connect to a SPARQL end-point over HTTP, pose a SELECT query or an update query (LOAD, INSERT, DELETE).If given a SELECT query it returns the results as a data frame with a named column for each variable from the SELECT query, a list of prefixes and namespaces that were shortened to qnames is also returned.If given an update query nothing is returned.
