Why Librarians Should Embrace Linked Data

6140017255_815f69e70e_z

David Stuart of Research Information recently wrote, “If libraries are to realise the value of the data they have been building and refining over many years, then it is not enough for them to just embrace the web of documents, they must also embrace the web of data. The associated technologies may seem complex and impenetrable but the idea of libraries embracing the web of data doesn’t have to mean that every librarian has to embrace every bit of technology. The web of data refers to the publication of data online in a machine-readable format, so that individual pieces of information can be both linked to and read automatically.” Read more

Senzari’s MusicGraph APIs Look To Enhance Musical Journeys

MusicGraph image

News came the other week that Senzari had announced the MusicGraph knowledge engine for music. The Semantic Web Blog had a chance to learn a little bit more about it what’s underway thanks to a chat with Senzari’s COO Demian Bellumio.

MusicGraph used to go by the geekier name of Adaptable Music Parallel Processing Platform, or AMP3 for short, for helping users control their Internet radio. “We wanted to put more knowledge into our graph. The idea was we have really cool and interesting data that is ontologically connected in ways never done before,” says Bellumio. “We wanted to put it out in the world and let the world leverage it, and MusicGraph is a production of that vision.”

Since its announcement earlier this month about launching the consumer version on the Firefox OS platform that lets users make complex queries about music and learn and then listen to results, Senzari has submitted its technology to be offered for the iOS, Android, and Windows Mobile platforms.  “You can ask anything you can think of in the music realm. We connect about 1 billion different points to respond to these queries,” he says. Its data covers more than twenty million songs, connected to millions of individual albums and artists across all genres, with extracted information on everything from keys to concept extractions derived from lyrics.

Sem Tech Solution For Materials Design And Development Wins Small Business Innovation Research Grant

rsz_matontoA Small Business Innovation Research grant, sponsored by the U.S. Air Force through the Office of the Secretary of Defense, has gone to a semantic technology solution for materials design and development. The project is aligned with the Materials Genome Initiative  that’s targeted to accelerate the pace of discovery and deployment of advanced material systems.

“This will help to showcase the semantic web technologies and methodologies in a large and meaningful domain and application area,” says Sam Chance, Innovation Evangelist and Special Programs Lead at iNovex Information Systems, which is the principal investigator and technical agent for development and integration for the project that will leverage W3C semantic standards. The project also includes as team members the University of Queensland, Penn State University, SRI International’s Materials Laboratory, and with Cambridge Semantics for access to its semantic tools to be bootstrapped onto the solution.

The University of Queensland brings to the effort a high-level domain ontology to represent structured knowledge about materials, their structure and properties and the processing steps involved in their composition and engineering, as well as certain case studies and data sources around jet fuels for hypersonic flight that are considered part of the materials design domain. The group at Penn State has been involved with the Materials Genome Initiative and also brings to the work particular case studies and data sources, this time for materials with nickel alloy as the base system. SRI has case studies and data sources for turbine blade coating.

Ready, Set, Lightning! 5-Minute Talks at SemTechBiz

A favorite component of the Semantic Technology and Business Conference is  the Lightning Round: an hour of five-minute talks given by excited executives and entrepreneurs fighting the clock to get across their ideas in just five minutes. If the participants went over the time limit (which was boldly displayed for all of us in the packed audience to monitor) they were very politely clapped off the stage. Surprisingly, many of the presenters had their speeches timed to the second, but others would have killed for fifteen more seconds.

At the end of the hour, the crowd of attendees left with brains stuffed to the brim with new ideas about a wide range of topics. The following are just a few highlights from the action-packed hour. Read more

Big Data Means More Than Volume

[NOTE: This guest post is by Peter Haase, Lead Architect for Research and Development, fluid Operations.]

Photo of Peter HaaseIndustry engineers waste a significant amount of time searching for data that they require for their core tasks. When informed about potential problems, diagnosis engineers at Siemens Energy Services, an integrated business unit which runs service centers for power plants, need to access several terabytes of time-stamped sensor data and several gigabytes of event data, including both raw and processed data. These engineers have to respond to about 1,000 service requests per center per year, and end up spending 80% of their time on data gathering alone. What makes this problem even worse is that their data grows at a rate of 30 gigabytes per day. Similarly, at Statoil Exploration, geology and geographic experts spend between 30 and 70% of their time looking for and assessing the quality of some 1,000 terabytes of relational data using diverse schemata and spread over 2,000 tables and multiple individual databases [1]. In such scenarios, it may take several days to formulate the queries that satisfy the information needs of the experts, typically involving the assistance of experienced IT experts who have been working with the database schemata for years.

Siemens and Statoil Exploration are hardly the only companies faced with time-wasting Big Data issues, but the root of these issues is not simply the “big” aspect of their data. The real challenge is finding a way to efficiently and effectively mine data for value and insight, regardless of its volume.

The Arches Project Puts A Semantic And Geo-Spatial Spin On Cultural Heritage

Inventorying and managing cultural heritage data turns out to be a pretty complicated undertaking. The construction of a famous site may have lasted across different time periods, and its present location may span multiple districts. Buildings may be associated not only with famous architects but also with well-known residents. Or structures may have been constructed atop pre-existing entities.

Helping sort it all out is the work of The Arches Project, collaboration between the Getty Conservation Institute (GCI) and World Monuments Fund (WMF). The Arches effort grew out of GCI’s and WMF’s work to develop MEGA-Jordan, a purpose-built geographic information system (GIS) to inventory and manage archaeology sites at a national level for that country. But for this more generic and open-source take at accommodating any country, region or other institution worldwide responsible for the protection of immovable cultural heritage, the focus expanded from the geo-spatial to the semantic.

“We became very familiar with the CIDOC Conceptual Reference Model ontology,” says Alison Dalgity, who manages the Arches project on GCI’s side. The CRM provides definitions and a formal structure for describing the implicit and explicit concepts and relationships used in cultural heritage documentation. “We realized we needed something like that. Now, the GIS piece is only part of this – it’s nice to know where something is, but all the other relationships – the who, how, what and when and so on – have to be represented, too.”
