CHAIN-REDS Project Enhances Semantic Search And Extends Reproducibility Of Scientific Data

chainredspixThe CHAIN-REDS FP7 project, co-funded by the European Commission, has as a goal building a knowledge base of information, gathered both from dedicated surveys and other web and document sources, for largely more than half of the countries in the world, which it presents to visitors through geographic maps and tables. Earlier this month, its Knowledge Base and Semantic Search Engine for exploring the more than 30 million documents in its Open Access Document Repositories (OADR) and Data Repositories (DR) became available in a smartphone and tablet app, while the results of its Semantic Search Engine also now are ranked according to the January 2014 Ranking Web of Repositories. So, users conducting searches should see results in the order of the highest-ranked repositories.

The project has its roots in using semantic web technologies to correlate the data used to write scientific papers with the documents themselves whenever possible, says Prof. Roberto Barbera, of the Department of Physics and Astronomy at the University of Catania, as well as with applications that can be used to analyse the information. To drive to these ends, the CHAIN-REDS consortium semantically enriched its repositories and built its search engine on the related Linked Data. Users in search of information can get papers and data and, if applications are available, can be redirected to them on the project’s cloud infrastructure to reproduce and reanalyze the data.

“There is a huge effort in the scientific world about the reproducibility of science,” says Barbera.

Introduction to: Triplestores

Badge: Hello, my name is TriplestoreTriplestores are Database Management Systems (DBMS) for data modeled using RDF. Unlike Relational Database Management Systems (RDBMS), which store data in relations (or tables) and are queried using SQL, triplestores store RDF triples and are queried using SPARQL.

A key feature of many triplestores is the ability to do inference. It is important to note that a DBMS typically offers the capacity to deal with concurrency, security, logging, recovery, and updates, in addition to loading and storing data. Not all Triplestores offer all these capabilities (yet).

Triplestore Implementations

Triplestores can be broadly classified in three types categories: Native triplestores, RDBMS-backed triplestores and NoSQL triplestores. Read more

Breaking into the NoSQL Conversation

Rob Gonzalez, Cambridge SemanticsSemantic Web Community: I’m disappointed in us!  Or at least in our group marketing prowess.  We have been failing to capitalize on two major trends that everyone has been talking about and that are directly addressable by Semantic Web technologies!  For shame.

I’m talking of course about Big Data and NoSQL.  Given that I’ve already given my take on how Semantic Web technology can help with the Big Data problem on SemanticWeb.com, this time around I’ll tackle NoSQL and the Semantic Web.

After all, we gave up SQL more than a decade ago.  We should be part of the discussion.  Heck, even the XQuery guys got in on the action early!

Check out this Google Trends diagram.

Semantic Web vs. NoSQL on Google Trends

NoSQL came out of nowhere in 2009, and now dominates much of the database conversation on the web.  Document stores like MongoDB and CouchDB, distributed, key-value stores such as Riak and Cassandra, and other weird stores like Hadoop-as-database (never understood that usage myself) now dominate the conversation as the alternative to traditional, SQL databases.
