Google announced they’re rolling out new enhancements to their search technology and they’re calling it the “Knowledge Graph.”  For those involved in the Semantic Web Google’s “Knowledge Graph” is nothing new. After watching the video, and reading through the announcements, the Google engineers are giving the impression, to those familiar with this field, that they have created something new and innovative.

While it ‘s commendable that Google is improving search it’s interesting to note the direct translations of Google’s “new language” to the existing semantic web vocabulary. Normally engineers and researchers quote, or at least reference, the original sources of their ideas. One can’t help but notice that the semantic web isn’t mentioned in any of Google’s announcements. After watching the different reactions from the semantic web community I found that many took notice of the language Google used and how the ideas from the semantic web were repackaged as “new” and discovered by Google.

3M has opened up the 3M Healthcare Data Dictionary under an agreement with the Department of Defense and the Department of Veterans Affairs. According to the article, “The 3M Healthcare Data Dictionary will provide the core technology to enable semantic interoperability for the joint DoD/VA integrated Electronic Health Record (iEHR), making it possible to share medical knowledge and secure patient data between care providers at U.S. military treatment facilities located around the world and VA Medical Centers. Access to actionable clinical information whenever and wherever care is delivered will enable safer, better coordinated, and higher quality care for the country’s 32 million veterans, active service members, and their families.” Read more

Andrea Di Maio of Gartner recently articulated concerns about open data processing, particularly the divide between data professionals who have the skills to do so and those who do not. Di Maio writes, “Over the last four years open government and open data have been at the forefront of the debate on how governments can become more transparent, participative and efficient. The theory is well known: rather than (or alongside) providing the government’s interpretation or packaging of public data, this data should be made available in raw, open format for people to build their own views and applications… The downside is a deluge of data. People can easily drown in raw open data that is either too much or simply meaningless unless some processing takes place.” Read more

A new article reports, “After months of gratuitous hard work and cooperation by higher education students and experts, the Spanish version of DBpedia, also known as the Spanish Semantic Wikipedia, has finally come into being. The Spanish DBpedia contains 70 million data that account for 80% of the information in the Spanish Wikipedia and now rivals other languages like English or French… DBpedia is a project for extracting Wikipedia data and building a semantic version of this Internet encyclopaedia. It is a community effort for extracting structured information from the Wikipedia and making it accessible on the Web.” Read more

Rufus Pollock of the Open Knowledge Foundation reports, “Last Friday (May 4), the Ministry of Planning in Brazil launched the final version of the Brazilian Open Data Portal. In line with the federal government policy to promote the use of free software in public administration, the portal was made using only free and open source tools. Among them is the Open Knowledge Foundation’s open-source data portal software CKAN.

Velichka Dimitrova of the Open Knowledge Foundation recently discussed the launch of Yourtopia Italia, an open data portal for Italy. She writes, “In countries like Italy stark regional differences have dominated over time. Particularly in times of fiscal austerity when the country attempts to recover from an economic crisis with major social consequences, seeing how and why the South and the North differ is an important step in a consensus-building process to find solutions and realise collaboration with the citizens. The Open Economics Working Group of the Open Knowledge Foundation released YourTopia Italia – an application which gives the users a chance to input their priorities in eight categories of socio-economic progress: Labour Market, Education, Health, Environment and Energy, Science and Research, Household Income and Inequality, Public Safety, and Social Life.” Read more

Yesterday, we announced RDFa.info, a new site devoted to helping developers add RDFa (Resource Description Framework-in-attributes) to HTML.

Building on that work, the team behind RDFa.info is announcing today the release of “PLAY,” a live RDFa editor and visualization tool. This release marks a significant step in providing tools for web developers that are easy to use, even for those unaccustomed to working with RDFa.

“Play” is an effort that serves several purposes. It is an authoring environment and markup debugger for RDFa that also serves as a teaching and education tool for Web Developers. As Alex Milowski, one of the core RDFa.info team, said, “It can be used for purposes of experimentation, documentation (e.g. crafting an example that produces certain triples), and testing. If you want to know what markup will produce what kind of properties (triples), this tool is going to be great for understanding how you should be structuring your own data.”

Jenn Webb of O’Reilly recently interviewed Laura Dawson regarding metadata in the publishing industry. Webb writes, “Dawson says publishers are starting to understand that metadata is the only indication that an ebook exists (discussed at 0:10), but they still don’t quite know what “metadata” means or exactly how to fit it into a production process. She says publishers are tending to assign one person the duty of handling metadata and aren’t grasping that it’s integral to every department and stage in a workflow.” Read more

Google reports that the company’s news service, Google News “is undergoing a makeover and will now include content from the firm’s new social network. Google News, which has only gone live in the U.S. to date, will see Google+ conversations from people’s ‘circles’ and other high profile users right onto the search engine’s news homepage. In a blog post about the changes, Scott Zuccarino, product manager of Google News, said the feature brings Google+ conversations right to the Google News homepage. ‘Many news stories inspire vibrant discussions on Google+, and today we’re starting to add this content to both the News homepage, and the real-time coverage pages,’ Zuccarino wrote.” Read more

Jane Wakefield of the BBC reports that London plans to test a new “smart city” operating system. She writes, “Living Plan IT has developed its Urban OS to provide a platform to connect services and citizens.  With partners including Hitachi, Phillips and Greenwich council, it aims to use the Greenwich peninsula as a testbed for new technologies running on the system. The OS aims to connect key services such as water, transport, and energy. David Willetts, Minister for Universities and Science, was among the signatories to the partnership. ‘The development of smart cities in future is a crucial commercial opportunity for Britain, and London is the right place to be doing it,’ he said.” Read more
