DBpedia 2014 Announced

DBpedia logoProfessor Dr. Christian Bizer of the University of Mannheim, Germany, has announced the release of DBpedia 2014. DBpedia is described at dbpedia.org as  “… a crowd-sourced community effort to extract structured information from Wikipedia and make this information available on the Web. DBpedia allows you to ask sophisticated queries against Wikipedia, and to link the different data sets on the Web to Wikipedia data. We hope that this work will make it easier for the huge amount of information in Wikipedia to be used in some new interesting ways. Furthermore, it might inspire new mechanisms for navigating, linking, and improving the encyclopedia itself.”

The full announcement on the new release is reprinted below with Bizer’s permission.

DBpedia Version 2014 released

1. the new release is based on updated Wikipedia dumps dating from April / May 2014 (the 3.9 release was based on dumps from March / April 2013), leading to an overall increase of the number of things described in the English edition from 4.26 to 4.58 million things.

2. the DBpedia ontology is enlarged and the number of infobox to ontology mappings has risen, leading to richer and cleaner data.

The English version of the DBpedia knowledge base currently describes 4.58 million things, out of which 4.22 million are classified in a consistent ontology (http://wiki.dbpedia.org/Ontology2014), including 1,445,000 persons, 735,000 places (including 478,000 populated places), 411,000 creative works (including 123,000 music albums, 87,000 films and 19,000 video games), 241,000 organizations (including 58,000 companies and 49,000 educational institutions), 251,000 species and 6,000 diseases.

eXframe Platform Demos Power Of The Semantic Web For Biology

sccommonsA Drupal ++ platform for semantic web biomedical data – that’s how Sudeshna Das describes eXframe, a reusable framework for creating online repositories of genomics experiments. Das – who among other titles is affiliate faculty of the Harvard Stem Cell Institute – is one of the developers of eXframe, which leverages Stéphane Corlosquet’s RDF module for Drupal to produce, index (into an RDF store powered by the ARC2 PHP library) and publish semantic web data in the second generation version of the platform.

“We used the RDF modules to turn eXframe into a semantic web platform,” says Das. “That was key for us because it hid all the complexities of semantic technology.”

One instance of the platform today can be found in the repository for stem cell data as part of the Stem Cell Commons, the Harvard Stem Cell Institute’s community for stem cell bioinformatics. But Das notes the importance of the reusability aspect of the software platform to build genomics repositories that automatically produce Linked Data as well as a SPARQL endpoint, is that it becomes easy to build new repository instances with much less effort. Working off Drupal as its base, eXframe has been customized to support biomedical data and to integrate biomedical ontologies and knowledge bases.

Introducing SPARQLGraph, a Platform for Querying Biological Semantic Web Databases

sgDominik Schweiger, Zlatko Trajanoski and Stephan Pabinger recently wrote, “Semantic Web has established itself as a framework for using and sharing data across applications and database boundaries. Here, we present a web-based platform for querying biological Semantic Web databases in a graphical way.  Results: SPARQLGraph offers an intuitive drag &drop query builder, which converts the visual graph into a query and executes it on a public endpoint. The tool integrates several publicly available Semantic Web databases, including the databases of the just recently released EBI RDF platform. Furthermore, it provides several predefined template queries for answering biological questions. Users can easily create and save new query graphs, which can also be shared with other researchers.” Read more

New Opps For Libraries And Vendors Open Up In BIBFRAME Transition

semtechbiz-10th-125sqOpportunities are opening up in the library sector, both for the institutions themselves and providers whose solutions and services can expand in that direction.

These vistas will be explored in a session hosted by Kevin Ford, digital project coordinator at the Library of Congress at next week’s Semantic Technology & Business conference in San Jose. The door is being opened by the Bibliographic Framework Initiative (BIBFRAME) that the LOC launched a few years ago. Libraries will be moving from the MARC standards, their lingua franca for representing and communicating bibliographic and related information in machine-readable form, to BIBFRAME, which models bibliographic data in RDF using semantic technologies.

Drupal Deepens Semantic Web Ties

semtechbiz-10th-125sqAmong the mainstream content management systems, you could make the case that Drupal was the first open source semantic CMS out there. At next week’s Semantic Technology and Business Conference, software engineer Stéphane Corlosquet of Acquia, which provides enterprise-level services around Drupal, and Bock & Co. principal Geoffrey Bock will discuss in this session Drupal’s role as a semantic CMS and how it can help organizations and institutions that are yearning to enrich their data with more semantics – for search engine optimization, yes, but also for more advanced use cases.

“It’s very easy to embed semantics in Drupal,” says Bock, who analyses and consults on digital strategies for content and collaboration. At its core it has the capability to manage semantic entities, and in the upcoming version 8 it takes things to a new level by including schema.org as a foundational data type. “It will become increasingly easier for developers to build and deliver semantically enriched environments,” he says, which can drive a better experience both for clients and stakeholders.

Corlosquet, who has taken a leadership role in building semantic web capabilities into Drupal’s core and maintains the RDF module in Drupal 7 and 8, explains that the closer embrace of schema.org in Drupal is of course a help when it comes to SEO and user engagement, for starters. Google uses content marked up using schema.org to power products like Rich Snippets and Google Now, too.

A Look At LOD2 Project Accomplishments

lod2pixIf you’re interested in Linked Data, no doubt you’re planning to listen in on next week’s Semantic Web Blog webinar, Getting Started With The Linked Data Platform (register here), featuring Arnaud Le Hors, Linked Data Standards Lead at IBM and chair of the W3C Linked Data Platform WG and the OASIS OSLC Core TC. It also may be on your agenda to attend this month’s Semantic Web Technology & Business Conference, where speakers including Le Hors, Manu Sporny, Sandro Hawke, and others will be presenting Linked Data-focused sessions.

In the meantime, though, you might enjoy reviewing the results of the LOD2 Project, the European Commission co-funded effort whose four-year run, begun in 2010, aimed at advancing RDF data management; extracting, creating and enriching structured RDF data; interlinking data from different sources; and authoring, exploring and visualizing Linked Data. To that end, why not take a stroll through the recently released Linked Open Data – Creating Knowledge Out of Interlinked Data, edited by LOD2 Project participants Soren Auer of the Institut für Informatik III Rheinische Friedrich-Wilhelms-Universität; Volha Bryl of the University of Mannheim, and Sebastian Tramp of the University of Leipzig?
