On Knowledge-Based Representations for Actionable Data …

I bumped into a professional acquaintance last week. After describing briefly a presentation I was about to give, he offered to broker introductions to others who might have an interest in the work I’ve been doing. To initiate the introductions, I crafted a brief description of what I’ve been up to for the past 5 years in this area. I’ve also decided to share it here as follows: 

As always, [name deleted], I enjoyed our conversation at the recent AGU meeting in Toronto. Below, I’ve tried to provide some context for the work I’ve been doing in the area of knowledge representations over the past few years. I’m deeply interested in any introductions you might be able to broker with others at York who might have an interest in applications of the same.

Since 2004, I’ve been interested in expressive representations of data. My investigations started with a representation of geophysical data in the eXtensible Markup Language (XML). Although this was successful, use of the approach underlined the importance of metadata (data about data) as an oversight. To address this oversight, a subsequent effort introduced a relationship-centric representation via the Resource Description Format (RDF). RDF, by the way, forms the underpinnings of the next-generation Web – variously known as the Semantic Web, Web 3.0, etc. In addition to taking care of issues around metadata, use of RDF paved the way for increasingly expressive representations of the same geophysical data. For example, to represent features in and of the geophysical data, an RDF-based scheme for annotation was introduced using XML Pointer Language (XPointer). Somewhere around this point in my research, I placed all of this into a framework.

A data-centric framework for knowledge representation.

 In addition to applying my Semantic Framework to use cases in Internet Protocol (IP) networking, I’ve continued to tease out increasingly expressive representations of data. Most recently, these representations have been articulated in RDFS – i.e., RDF Schema. And although I have not reached the final objective of an ontological representation in the Web Ontology Language (OWL), I am indeed progressing in this direction. (Whereas schemas capture the vocabulary of an application domain in geophysics or IT, for example, ontologies allow for knowledge-centric conceptualizations of the same.)  

From niche areas of geophysics to IP networking, the Semantic Framework is broadly applicable. As a workflow for systematically enhancing the expressivity of data, the Framework is based on open standards emerging largely from the World Wide Web Consortium (W3C). Because there is significant interest in this next-generation Web from numerous parties and angles, implementation platforms allow for increasingly expressive representations of data today. In making data actionable, the ultimate value of the Semantic Framework is in providing a means for integrating data from seemingly incongruous disciplines. For example, such representations are actually responsible for providing new results – derived by querying the representation through a ’semantified’ version of the Structured Query Language (SQL) known as SPARQL. 

I’ve spoken formally and informally about this research to audiences in the sciences, IT, and elsewhere. With York co-authors spanning academic and non-academic staff, I’ve also published four refereed journal papers on aspects of the Framework, and have an invited book chapter currently under review – interestingly, this chapter has been contributed to a book focusing on data management in the Semantic Web. Of course, I’d be pleased to share any of my publications and discuss aspects of this work with those finding it of interest.

With thanks in advance for any connections you’re able to facilitate, Ian. 

If anything comes of this, I’m sure I’ll write about it here – eventually!

In the meantime, feedback is welcome.

Recent Articles on Bright Hub

I’ve added a few more articles over on Bright Hub:

Blended Learning Panel

York University’s Institute for Research on Learning Technologies is sponsoring a panel discussion on blended learning:

“A recent workplace survey reported by Brandon Hall Publishing (2008) indicates that employing a mix of web-technologies with face-to-face learning is more effective than either e-learning or face-to-face instructional approaches alone. To explore the use and potential of “blended learning” further, please join us for a panel discussion featuring experts from various fields …”

This event has been re-scheduled for April 2, 2009 at 12:15 pm in TEL 1009 at York’s Keele Campus. I anticipate a lively and interesting discussion!

(Please check the IRLT Web site for the latest updates on the event.)

CANHEIT 2009: Call for Proposals Open

Since my return to York, an annual highlight has been participation in CANHEIT – The Canadian Higher Education IT Conference. The 2009 conference is being hosted by The University of Montreal. The Call for Proposals opened a few days ago and will remain open until the end of January 2009. That gives us something to ponder over the holidays …

Google Chrome for Linux on Bright Hub: Series Expanded

I recently posted on a new article series on Google Chrome for Linux that I’ve been developing over on Bright Hub. My exploration has turned out to be more engaging than I anticipated! At the moment, there are six articles in the series:

• Google Chrome for Linux: Building from Source
• Google Chrome for Linux: Testing and Contributing
• Google Chrome for Linux: The WebKit Web Browser Engine
• Google Chrome for Linux: The V8 JavaScript Engine
• Google Chrome for Linux: Why V8 Bests WebKit’s JavaScript Engine
• Google Chrome for Linux: Android Availability

I anticipate a few more …

It’s also important to share that Google Chrome for Linux does not yet exist as an end-user application. Under the auspices of the Chromium Project, however, there is a significant amount of work underway. And because this work is taking place out in the open (Chromiun is an Open Source Project), now is an excellent time to engage – especially for serious enthusiasts.

Google Chrome for Linux Articles on Bright Hub

I’ve recently started an article series over on Bright Hub. The theme of the series is Google Chrome for Linux, and the series blurb states:

Google Chrome is shaking up the status quo for Web browsers. This series explores and expounds Chrome as it evolves for the Linux platform.

So far, there are the following three articles in the series:

• Google Chrome for Linux: Building from Source
• Google Chrome for Linux: Testing and Contributing
• Google Chrome for Linux: Android Availability

I intend to add more … and hope you’ll drop by to read the articles.

Stainless Improving By Leaps and Bounds!

When I first wrote about Stainless, I indicated that it provided impressive features/functionalities for a version 0.1 release. In a subsequent post, I elaborated on Stainless’ strengths and weaknesses. 

Stainless is now at version 0.2.5. And in the space of a few weeks, Mesa Dynamics has addressed a number of the weaknesses I previously noted. Specifically:

• Download capability – It just works now! Thanks!
• Offline mode – Via Google Gears. Interestingly, I predicted this might take some time. I am so happy to be wrong!!

The release notes for Stainless provide the details on these and numerous other improvements.

So, what’s left? In order for me to shift to Stainless as my ‘production browser’, I really need:

• Interaction with Google Notebook – Even via the bookmarklet is fine! 
• URL Caching/Auto-Completion – As noted previously … 

Even with these production must-haves, Stainless is well worth a look today.
