The Aite Group, which provides research and consulting services to the international financial services market, spends its fair share of time exploring the data and analytics challenges the industry faces. Senior analyst Virginie O’Shea commented on many of them during a webinar this week sponsored by enterprise NoSQL vendor MarkLogic.

Dealing with multiple data feeds from a variety of systems; feeding information to hundreds of end users with different priorities about what they need to see and how they need to see it; a lack of a common internal taxonomy across the organization that would enable a single identifier for particular data items; the toll ETL, cleansing, and reconciliation can take on agile data delivery; the limitations in cross-referencing and linking instruments and data to other data that exact a price on data governance and quality – they all factor into the picture she sketched out.

Perfect Memory’s Goal: Help You To Make More From Your Media Content

rsz_pmemThere’s a growing focus on the opportunity for semantic technology to help out with managing media assets – and with making money off of them, too. Last week, The Semantic Web Blog covered the EU-funded project Media Mixer for repurposing and reusing media fragments across borders on the Web. Also hailing from Europe – France, to be exact – is Perfect Memory, which aims to support the content management, automatic indexing and asset monetizing of large-scale multimedia.

Perfect Memory, which was a finalist at this spring’s SemTechBiz semantic start-up competition, has implemented its platform at Belgian TV broadcaster and radio RTBF, for its GEMS semantic-based multimedia browser prototype that was a runner-up at IBC 2013 this fall. In September it also received a 600K Euro investment from SOFIMAC Partners to extend its development efforts, platform, and market segments, as well as protect its innovations with patent filings.

“Our idea is to reinvent media asset management systems,” says Steny Solitude, CEO of Perfect Memory.

Semantic Tech To The Rescue For Medicare Administrative Contractor

rsz_readWhen a Medicare administrative contractor found itself under the gun to improve its performance in order to retain its business with the Centers for Medicare & Medicaid Services, it was able to leverage semantic technology to realize its goals.

The audience at last week’s Semantic Technology & Business Conference heard about this case study from management consultancy Blue Slate Solutions, which specializes in improving and transforming operations through business process and analytic transformation and which spearheaded the semantic project for the contractor. “This client was struggling in the medical review process, to decide if claims should be paid,” recounted David S. Read, Blue Slate CTO.

New Semantic Service Aims At Diggng Out The Dollars

Digging out money. That’s the mission of VitalFlux’s ShriGB, which aims to extract meaningful insights from financial Big Data published from various financial portals and make it consumable to users with different needs, from financial brokers to job seekers.

The app right now is focusing on portals in the Indian marketplace, putting its artificial intelligence to work in its learning phase to create appropriate ontologies, taxonomies and relationships, according to founder and CEO Ajitesh Shukla. The plan is to migrate it to other markets in future. “Once the system starts getting mature, this shall be moved to the global arena,” says Shukla. “It is also understood that different countries financial portals have different ontologies and system may need to get appropriate learning to work appropriately for these countries.”

Big Data Is Big Focus At SemTechBiz (Part 2)

LOGO: Semantic Technology & Business Conference; June 2-5, 2013, San Francisco, CaliforniaOur discussion of Big Data at SemTechBiz, begun here, continues:

The Enterprise Linked Data Cloud Needs Semantics, And More

Another exploration of Big Data’s intersection with semantic technology will take place at this session, where Dr. Giovanni Tummarello, senior research fellow at DERI and CTO of SindiceTech, will talk about the former becoming an enabler for the latter to be really useful in enterprises. “A lot of people say it’s via Big Data that semantic technologies like RDF will see a coming of age and clear applications in certain industries,” he says. There’s value to adding data first and understanding it later, and to that end, “semantic technologies give you the most agile tool to deal with data you don’t know, where there’s a lot of diversity, and you don’t know what of it particularly will be useful.”

An Overview of RDF Triple Stores

Lars Marius Garshol has posted an overview of RDF triple stores. He writes, “There’s a huge range of triple stores out there, and it’s not trivial to find the one most suited for your exact needs. I reviewed all those I could find earlier this year for a project, and here is the result. I’ve evaluated the stores against the requirements that mattered for that particular project. I haven’t summarized the scores, as everyone’s weights for these requirements will be different.” Read more

Big Data and the Semantic Web: Their Paths Will Cross

Big Data and the Semantic Web are on a track to intersect. And businesses that want to be on track to profit from the explosion in data should start looking a little more closely at that intersection, and soon.

“We’ve got more data now than ever before coming at us, and it is coming faster and faster,” says Frank Coyle, director of the Software Engineering program in the Lyle School of Engineering at Southern Methodist University, whose research is in the area of web services and semantic web technologies. “So the semantic angle is how can you organize this data to take advantage of it, to do queries over it.” Those in the semantic web community say RDF is the way to go, he says, adding that people now use the term linked data as another way of describing semantic data. “If you take Big Data and link it, then you have semantics – you have meaning now introduced into the equation.”

Turtle and Linked Data

Kingsley Idehen has written a series of articles discussing “why Turtle is such an important syntax for crafting Web documents comprised of Linked Data based structured content. Basically, this markup language addresses the biggest challenges to Linked Data comprehension which include the following: (1) triple visibility, (2) triple comprehension. Once you get beyond triple visibility and comprehension, the next challenge for Linked Data is deployment. Historically, this effort has been mired by the following.” Read more

Step-by-Step: Putting WorldCat Data Into Triple Stores

Richard Wallis has followed up his recent announcement that WorldCat data can now be downloaded as RDF triples with an explanation of how to put that data into a triple store. He begins: “Step 1: Choose a triplestore.  I followed my own advise and chose 4Store.  The main reasons for this choice were that it is open source yet comes from an environment where it was the base platform for a successful commercial business, so it should work.  Also in my years rattling around the semantic web world, 4Store has always been one of those tools that seemed to be on everyone’s recommendation list.” Read more

Vital.AI: A Semantic Platform for Big Data-Driven Apps

Yesterday The Semantic Web Blog discussed how personalized mobile assistance came up on the lists of a bright future in the eyes of semantic web experts (see here). Sharing that vision is the team at Vital.AI, the NYC-startup founded by Marc Hadfield.  Its Thrive.AI app, also a contender at SemTech’s Startup Competition, is a personalized semantic shopping agent for the iPad, but the underlying Vital.AI platform on which it is built provides an integrated suite of components for a variety of knowledge-centric, intelligence-rich, Big Data-driven applications.

The e-commerce agent, Hadfield told attendees at SemTech in San Francisco last week, was the company’s own foray into figuring out what it needed to add to the platform to make it easier to build apps that bring semantic technologies and Big Data together.
