So the day on tutorial is over. There were many choices, many activities and many participants trying to decide on which talk to hit on before it started at 8:30 this morning. The topics on the first half of the tutorials were presented asynchronously and were equally competitive in nature. From the plethora of choices, I decided to hit the first tutorial on The Future of Social Networks: The Need for Semantics by the DERI team. However, I quickly realized that there were other interesting things going on in parallel, so I moved on to W3C Tutorial: Using Semantic Web Data: Query, Inference, and Proof by Eric Prud’hommeaux of W3C. Well, guess what? Even that was not enough. I was craving for something more, so I decided to land onto Semantically-Enabled Service Oriented Architectures by the Zepheira team – Brian Sletten and Uche Ogbuji. The first half of the day was over and were ready for lunch by noon.

For the second half which started at 1:15 PM, I sorta juggled between the two sessions again to wet my appetite. First I went to Dynamic and Agile SOA using SAWSDL by Amit Sheth and the team from Knoesis, then half way I sneaked into Semantic Resource Oriented Architectures (ROA): The Next Generation of Enterprise Services by David Wood and Brian Sletten from Zepheira. Both talks were equally intriguing and informative on what has been established in the Semantic Web space for the Enterprise.


SemTech 2008 fired off today in Fairmont San Jose with an Introduction to Semantic Technology and the State of Semantic Web. Both the speakers were elegant and packed with an au fait in the Semantic Technology subject matter. It was Dave McComb for the first topic and Ivan Herman for the latter. Dave ignited the conference with the latest on Semantic Technology and greeted the audience with the notion of Boiled Frog as an analogy to how we are being boiled in data – the massive amount of data we are drowning in. He jumped right into the topic and introduced the T-Box and A-Box theories pertaining to Semantic Web. He mentioned that these theories can be related approximately to classes and instances, but not quite. T-Box is transitive box and A-Box is assertive.

Then, he went on to explain something very descriptive that I was longing to hear an explanation on for a while. He mentioned about the components involved in creating the entire Semantic Web solution. He showed a simple diagram to the audience mentioning the Data Extraction (DE) and Entity Extraction (EE) as the source to Semantic Web data. Data extraction can be something mapped from other data sources to RDF or OWL where as Entity Extraction is to create structured data from other data sources using NLP or similar tool. Then the RDF or OWL can be stored in a Triple Store. The data in the Triple Store can be referred to using Description Logic which then can be Inferred using Rules or analyzed using complex algorithms. These set of components were shown in the diagram to help the audience visualize the complete flow. Finally, he showed the same Boiled Frog as a disclaimer to prove that no frogs were harmed during the creation of his slides.

Right after Dave McComb was done, there was a 15 minute break and then started Ivan Herman’s talk. He started off with the tools and current state of the art in the Semantic Web technology. He showed several tools available in specific areas of Semantic Web and how far we have come with the tools, open source or commercial, in the current market.

A new search engine tool that understands your language. You can ask a question and it will give you an answer in a meaningful way around the context of what you have asked for. What does that mean? Meaning, if you ask “Who is Paris Hilton?”, it knows the difference between Hilton Hotel in Paris and the exorbitant Paris Hilton, unlike Google where Paris can be either – a person or hotel. All over the Web, you can find a lot of notes and blogs on what Powerset can do and whether it can defeat Google. Here is for you to find out – Powerset. Post comments about your thoughts on this “supposedly” new and intelligent search engine.

Hello, world!

Welcome to my new blog host.

If you have ever wondered of unimaginable things come to life, here is one that may amaze you with shock and awe. The researchers in the Brain-Computer Interface have come out of the cave and introduced the First Brain-Computer Interface for Mainstream Consumers. This device that looks like a headphone can sense your brain signals off of your scalp and control the movement of a cursor on a screen. This deus ex machina was recently introduced to the market by Emotiv Systems and the device is called EPOC Headset. The headset will be priced $299 once it starts its production and mainly be focused on gaming industry for now.

An introduction of such device makes me believe that someday Matrix will be live. How soon? That is for you to find out. Learn more @ Think Artificial

Twine? A site completely based on the Semantic Web technology implemented by Radar Networks (in San Francisco). It is a new way of organizing your personal information that enables you with an easy access and navigation. From the demo, it represented itself as a content bookmark where you can organize, share and discover any type of information you find in the Web to be parsed and logged into Twine. Unlike Facebook where the network is only limited to people, Twine can be of anything. Powered by semantic understanding, Twine automatically organizes information, learns about your interests and makes connections and recommendations. The more you use Twine, the better it understands your interests and the more useful it becomes.

So is Twine hot or not? I say it is recherché.
