Success for Open Data at OKFest

Mark Wainwright of OKF writes, “Last week’s OKFest is finally over, after a hectic week of talks, workshops, films, hackathons, and more. You can read about highlights such as Hans Rosling’s brilliant talk over on the OKFN blog. The biggest challenge for me was being in two places at once on Wednesday afternoon, with both the CKAN workshop and a panel discussion, including me, in the Open Science stream on ‘Immediate access to raw data from experiments’, where I was on the panel, running in nearby buildings at overlapping times. (Happily I more or less pulled it off.)” Read more

Semantic Web Jobs: LGS Innovations

LGS Innovations is looking for an NTOC Data Modeler in Laurel, MD. According to the post, this position will “Perform primary research using available resources and subject matter experts to identify how data sources would map into existing data atoms and identify new atoms needed to fill any gaps. Perform semantic data modeling for the NTOC domain logical data model and/or data sources.  Skills needed across the two positions include Semantics, Ontology, Epistemology, Resource Description Framework (RDF) Schema (RDFS), OWL based technologies, Hadoop, SPRQL, XML, XSD, and Data Warehouse, and Oracle, SQL, and relational theory. Develop and maintain NTOC domain logical data model artifacts: Logical Data Models (LDM), Data Element Dictionaries (DED), Physical Data Models (PDM), Interface Control Documents (ICD), data format specifications, model release documentation, user guides, data harmonization and mappings.” Read more

Fast Access to Complex Data through Graph Databases

Emil Eifrem, founder of Neo4j has written an article for Mashable about the rise of graph databases. He writes, “Until the NOSQL wave hit a few years ago, the least fun part of a project was dealing with its database. Now there are new technologies to keep the adventuresome developer busy. The catch is, most of these post-relational databases, such as MongoDB, Cassandra, and Riak, are designed to handle simple data. However, the most interesting applications deal with a complex, connected world. A new type of database significantly changes the standard direction taken by NOSQL. Graph databases, unlike their NOSQL and relational brethren, are designed for lightning-fast access to complex data found in social networks, recommendation engines and networked systems.” Read more

Semantic Search: Trends, Uses, and the Future

Barbara Starr recently discussed on Search Engine Land how search engines and social engines are incorporating semantic search. She writes, “The term ‘Semantic Search’ is certainly not new. However, it has taken on a new dimension and implications in both search and social engines today. In addition, it has had a strong impact on targeted semantic advertising. This special series of forthcoming articles on semantic search will take a look at the history behind the development of semantic technology and why it has now become so commercially viable and topical. It will also take a look at how the technology enables “answer engines,” rather than simple search engines, to improve the user experience.” Read more

Quant Finance Shops Can Add Sentiment About Macroeconomic and Geopolitical Events To Their Rules Toolbelts

Real-time macroeconomic and geopolitical events and sentiment about them now figure into RavenPack News Analytics 3.0, to help financial firms react more quickly to what’s happening in the world.

The solution is aimed at quant finance shops, such as hedge funds, banks, and some financial research houses, where the machines are doing the trading. It’s a part of the market that’s had some rough times of late because of some trading errors, but in general quant firms represent a growing piece of the financial space, says RavenPack Head of Sales and Business Development Hugh Taggart.

Transforming Relational Data to RDF – R2RML Becomes Official W3C Recommendation

World Wide Web Consortium LogoToday, the World Wide Web Consortium announced that R2RML has achieved Recommendation status. As stated on the W3C website, R2RML is “a language for expressing customized mappings from relational databases to RDF datasets. Such mappings provide the ability to view existing relational data in the RDF data model, expressed in a structure and target vocabulary of the mapping author’s choice.” In the life cycle of W3C standards creation, today’s announcement means that the specifications have gone through extensive community review and revision and that R2RML is now considered stable enough for  wide-spread distribution in commodity software.

Photo of Richard CyganiakRichard Cyganiak, one of the Recommendation’s editors, explained why R2RML is so important. “In the early days of the Semantic Web effort, we’ve tried to convert the whole world to RDF and OWL. This clearly hasn’t worked. Most data lives in entrenched non-RDF systems, and that’s not likely to change.”

Semantic Web Jobs: University of Miami

The University of Miami is looking for a Software Engineer. According to the post, “We are currently looking for a software engineer to participate in the design and construction of software tools that are being developed as part of the BAO, LIFE and RegenBase projects. These tools will facilitate the search, exploration, visualization and analysis of complex data generated by chemical biology experimental systems. The emphasis of these projects is on the development of user friendly search applications that leverage semantic models to help retrieve the most relevant results as quickly as possible. We will also be exploring methods of presentation and visualization.” Read more

Open Government Partnership Celebrates First Anniversary

Kedar Pavgi of reports, “A year ago, President Obama and 46 other heads of state launched the Open Government Partnership, an initiative designed to increase transparency within governments around the world. The group’s declaration said that all adherent countries would: (1) Promote openness, because more information about governmental activities should be timely and freely available to people; (2) Engage citizens in decision-making, because this makes government more innovative and responsive; (3) Implement the highest standards of professional integrity, because those in power must serve the people and not themselves; and (4) Increase access to new technologies because of their unprecedented potential to help people realize their aspirations for access to information and a more powerful voice in how they are governed.” Read more
