In August, we had the pleasure of hosting the excellent instructor, Bob DuCharme, as he walked us through an introduction to SPARQL: “SPARQL Queries, SPARQL Technology.” Next week, Bob will join us again, this time to introduce us to SKOS, the Simple Knowledge Organization System standard.
You manage a taxonomy, thesaurus, or some other kind of controlled vocabulary using a proprietary tool or perhaps even by emailing around spreadsheets to each other. Read more
If you missed last week’s excellent introduction to SPARQL by Bob DuCharme of TopQuadrant and the recently released Learning SPARQL, the recorded webcast is now available. In this presentation, Bob shows how to create and run SPARQL queries. He also talks about the role that the query language can play in application development. Lastly, he looks at the range of uses people are finding for SPARQL above and beyond querying of RDF data, such as querying relational data, defining rules to enhance data quality, and more…

There were some questions we did not get to during the hour, and Bob has been kind enough to answer these offline.
BONUS Q&A with Bob DuCharme:
Q: Can sparql engines integrate reasoners and reason over the data on the fly? Read more
Bob DuCharme, the presenter of next week’s webcast SPARQL Queries, SPARQL Technology recently wrote a brief article showing how simple RDFa can be. DuCharme begins, “I got so tired of hearing people complain about how confusing RDFa is that while I was on hold during a recent phone call I threw together a demo of just how simple it can be. The document has the two basic kinds of triples: one with a literal for an object, with data typing thrown in for good measure, and one with a resource URI as its object.” Read more
A quirky new article likens search engines to humongous babies. The article states, “You can’t expect it to understand complicated things. You would never try to teach language to a human baby by reading it Nietzsche, and you shouldn’t expect a baby google to learn bibliographic data by feeding it MARC (or RDA or METS or MODS, or even ONIX). When a baby says ‘goo-goo’ to you, you don’t criticize its misuse of the subjunctive. You say ‘goo-goo’ back. When Google tells you that that it wants to hear ‘schema.org’ microdata, you don’t try to tell it about the first indicator of the 856 ‡u subfield. You give it schema.org microdata, no matter how babyish that seems.” Read more
If it’s been a while since you have looked in on the conference program for SemTech SF, you may have missed the addition of some significant, exciting sessions. Recent additions to this year’s conference include:
Aditya Kalyanpur, research staff member for IBM Research will lead a session entitled “Building Watson: An Overview of the DeepQA Project for the Jeopardy! Challenge,” a discussion of the the DeepQA technology and describe what it was like to build a Watson, the computer system that won on Jeopardy!.
“The rise of the Interest Graph: How Semantic Technology Will Lead What’s Next for the Social Web.” Dave S Copps, CEO of PureDiscovery Corporation, will discuss the reasons why transactional searches will be replaced by social filtering. The real power and potential of semantic technologies will be unleashed as semantic vendors integrate the richness of the data being generated by the social graph (Twitter, Facebook, etc.) to create networks that share more than just a relationship.
A new paper has been release by IBM entitled “Improve your taxonomy management using the W3C SKOS standard.” The paper is written by Bob DuCharme, a solutions architect at TopQuadrant and SemTech 2011 presenter. According to the summary, “Until recently, tools for managing controlled vocabularies, taxonomies, and thesauri all stored their data using proprietary formats that made the data difficult to integrate with external systems. The W3C SKOS standard defines a portable, flexible controlled vocabulary format that is increasingly popular, with the added benefit of a good entry-level step toward the use of Semantic Web technology.” Read more
This article takes a look at one of the new features in TopBraid Composer 3.5 – the Web Data Basket view: “This can be used to incrementally download Linked Data (either RDFa or RDF) while browsing the web. The best way to experience this is by getting a small TBC Firefox extension. This will add a tiny TopBraid button to the lower right corner of your browser. Click on this button while TopBraid Composer is executing, and all RDF data encoded on the currently visited page will be added to TBC’s Web Data Basket.” Read more
