About the Webinar

Interoperability of electronic healthcare information remains an enormous challenge in spite of 100+ available healthcare information standards. This webinar explains the Yosemite Project, whose mission is to achieve semantic interoperability of all structured healthcare information through RDF as a common semantic foundation. It explains the rationale and technical strategy of the Yosemite Project, and describes how RDF and related standards address a two-pronged strategy for semantic interoperability: facilitating collaborative standards convergence whenever possible, and crowd-sourced data translations when necessary.

Linked Data LEAPS To More Sustainable Energy Sources

leapspixAt the IESD14 (Intelligent Exploration of Semantic Data) challenge at this week’s ISWC 2014, the award was handed out to LEAPS: A Semantic Web and Linked Data Framework for the Algal Biomass Domain. The application is the work of Monika Solanki, Knowledge-Based Engineering Lab at Birmingham City University in the UK.

The motivation, according to slides about the project, relates to the idea that algae biomass-based biofuels could serve as a naturally viable and sustainable energy source alternative to fossil fuels. While many companies, governments and non-profit agencies have been researching the idea, knowledge gathered exists in diverse formats and proprietary databases. What’s lacking has been a knowledge level infrastructure that is equipped with the capabilities to provide semantic grounding to the datasets for algal biomass, the slides note.

Introducing GEMS, a Multilayer Software System for Graph Databases

gemsThe Pacific Northwest National Laboratory recently reported on Phys.org, “As computing tools and expertise used in conducting scientific research continue to expand, so have the enormity and diversity of the data being collected. Developed at Pacific Northwest National Laboratory, the Graph Engine for Multithreaded Systems, or GEMS, is a multilayer software system for semantic graph databases. In their work, scientists from PNNL and NVIDIA Research examined how GEMS answered queries on science metadata and compared its scaling performance against generated benchmark data sets. They showed that GEMS could answer queries over science metadata in seconds and scaled well to larger quantities of data.” Read more

Symplectic Takes Another Step In Helping Universities Engage In Research Collaboration And Discovery

sympintThis summer, Symplectic Limited become the first DuraSpace Registered Service Provider (RSP) for the VIVO Project, an open-source, open-ontology, open-process platform for hosting semantically structured information about the interests, activities and accomplishments of scientists and scholars. (See our coverage here.) “Universities want to capture all that their researchers do, collaborate and reuse the data the research brings out,” says Sabih Ali, head of brand at Symplectic. “A lot of them are looking to be a part of something like VIVO and join the whole semantic web technology movement, but they don’t have the capacity to do it themselves.”

Symplectic brings that to the table with its role as a services provider and the expertise in data quality, organization and transfer that it has thanks to being a developer of Elements, software that captures, collects and showcases institutional research, and which is used by many leading universities including Cambridge and Oxford. It also offers an open-source VIVO harvester for clients allows the ingestion of information into VIVO profiles using the rich data that Elements captures.

More recently, Symplectic has taken on the role of authorized services provider for Profiles Research Networking Software, as well. Profiles RNS is an NIH-funded open source tool to speed the process of finding researchers with specific areas of expertise for collaboration and professional networking. It’s based on the VIVO 1.4 ontology, with support for RDF, SPARQL, and Linked Open Data.

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.
