On Friday, September 15, a group of Semantic Technology thought leaders from around the globe met with their host and colleague, Paul Miller, for the latest installment of the Semantic Link, a monthly podcast covering the world of Semantic Technologies. This episode includes a discussion about Big Data and Semantics, as well as some discussion of general trends in the Semantic Technology space.

Explore #SemTechBiz San Francisco on FluidOps IWB

Last week, we published Under the Hood: A Closer Look at Information WorkBench, an interview with Peter Haase conducted by Kristen Milhollin as part of her series on Dynamic Semantic Publishing.

We are pleased to announce that FluidOps has created a viewer for the SemTechBiz conference program in Information Workbench.  The viewer is a good example of a faceted, semantic viewer for the conference program data, including map, timeline, and graph views, and tying in data from disparate sources such as Facebook, Twitter, and the conference program itself.

Of course, we have the conference agenda-at-a-glance here, and will make the program available to conference attendees via the Guidebook app for mobile devices, but this is an interesting example of Semantic Technology at work in a human-friendly user interface.

Thanks to Peter Haase and the FluidOps team for this work!

Google’s Knowledge Graph Is No Ugly Duckling

I’m a fan of the waterfowl model of semantic technology. Clever semantics — as well as ‘advanced’ search boxes, arcane query syntax, and consumer interfaces that require user training — can paddle away as frantically as they like, but only while hidden well below the waterline. SPARQL, SKOS and SQL really shouldn’t be visible to most users of a web site. Ontologies and XML are enabling technologies, not user interface features.

With this week’s unveiling of the Knowledge Graph, Google has taken another step toward realising the potential of their Metaweb acquisition. The company has also clearly demonstrated its continued enthusiasm for delivering additional user value without requiring changes in user behaviour (well, except that those of us outside the US have to remember to use google.com and not our local version, if we want to try this out).

For those who don’t remember, Metaweb was one of those companies that got people excited about the potential for semantic technologies to hit the big time. Founded way back in 2005, Metaweb attracted almost $60Million in investment for their “open, shared database of the world’s knowledge” (Freebase) before disappearing inside Google in 2010.

Web Developers Can Now Easily “Play” with RDFa

Kids playingYesterday, 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.”

Global Accessibility Awareness Day is Today – but where’s the Sem Tech?

Global Accessibility Awareness Day LogoToday, May 9, 2012 is Global Accessibility Awareness Day (#GAAD). What started with a simple blog-post by Los Angeles Web Developer, Joe Devon, has grown to include events around the world designed to increase awareness about web accessibility issues. To read more about the day and these various activities, see the official GAAD Website and Facebook page.

According to the US Centers for Disease Control and Prevention, “Today, about 50 million Americans, or 1 in 5 people, are living with at least one disability, and most Americans will experience a disability some time during the course of their lives.” In other parts of the world, this number may be significantly higher.

In the interest of full disclosure, Joe Devon is a personal friend of mine, and I must admit that if he were not, I likely wouldn’t have seen his blog post or explored the issues of accessibility as deeply as I have in recent weeks. But I have been exploring, and I’ve been surprised at what I’ve found. In my opinion, Semantic Technology and Assistive Technology are a natural fit for one another, but there seems to be very little discussion or work around the intersection of the two. I have looked, but have not found much collaboration between the two communities. I have also found few individuals who possess much knowledge about both Semantic Tech and Assistive Tech. Of course, if I’ve missed something, please let me know in the comments!

Burying complexity for the sake of good user experience

buried cable warning“There’s our SPARQL endpoint.” Or “Just view the page in Tabulator.” I have lost count of the number of times that either of these have been the only response to an innocent request to see what some new piece of semantic wizardry can do. For a developer seeking to integrate one semantics-rich data set with another, SPARQL may very well be the tool for the job. And for someone (probably a developer, again) who wants to track the way that data is pulled together to build a page, Tabulator has a lot going for it. But as a shop window for the power of semantics? As a demonstration of what’s possible? Seriously, is it possible to pick worse ways to show off to the world?

In January’s episode of the Semantic Link, we were joined by serial entrepreneur Nova Spivack (perhaps best known to readers as the Founder and CEO of Twine) for a discussion about the importance of delivering a good user experience. In the time available, we only scratched the surface, and I’m sure it’s a topic to which we’ll return. Read more

Nova Spivack joins the Semantic Link to discuss the user’s experience of semantic technologies

…and we want to hear from you.

Photos of our regular panelists.

After December’s episode of the Semantic Link, we asked for your thoughts on both the topics we should cover, and the ways in which you would like to interact with the podcast. You spoke, very clearly asking for an opportunity to pose questions for the team to answer during recordings. This is that opportunity.

Photo of Nova SpivackJanuary’s episode of the show will be recorded this Friday, 13 January, and we’re joined by a guest with much to contribute. I’m sure he needs no introduction for most of you. Nova Spivack was behind semantic technology startup Twine, and has subsequently turned his hand to supporting a range of semantically relevant offerings such as Bottlenose (our coverage) and StreamGlider (our coverage).

Drawing upon some of Nova’s experiences, and digging further into questions that we have touched upon before, we’re going to take a look at the following topic this month:

Is it important to hide semantic smarts behind a simple user experience/interface? If not, why not? If so, how are we beginning to see that manifested?

Siri‘s obviously one example that we’ve discussed before, but there have been other examples recently that also attempt to hide significant power behind UI simplicity. Read more

Liner Notes for YouTube – Seevl Plugin

Seevl.netSeevl, the music discovery service built on Semantic Technology that I wrote about a few months ago, has released a significant update to their plugin for YouTube. The plugin is still only available for the Google Chrome browser, but other browser plugins are in the works. You can grab the Chrome plugin here.

Once the plugin is installed, the user has new options available when visiting YouTube. First, there’s a new search option next to the standard YouTube search bar.

Index and Search Your Personal Cloud with Topicmarks

Topicmarks

“Our mission is to make long form content as easy and relevant as social media.”
–Topicmarks website

With the increasing popularity of cloud-based services for personal workflows, there is a parallel need for ways to organize that information. As part of my everyday workflow and information management routine, I use Evernote, Google Reader, Google Docs, DropBox, and a good number of locally stored files. I email files and links to myself frequently.  Each of these services is great in its own right, and I use them for different purposes and on different devices.  I use them for both personal and work-related information.

By the very nature of this workflow, I have created several silos I need to go to when I am ready to access information, and honestly, it’s not always easy to remember which silo something resides in. I have topics that span content in those different eco-systems, and it would be incredibly useful to have a centralized view into “everything I have saved or tagged on the topic of RDFa,” for example.

Enter Topicmarks.
