Minding the Planet

My Visit to DERI -- World's Premier Semantic Web Research Institute

Earlier this month I had the opportunity to visit, and speak at, the Digital Enterprise Research Institute (DERI), located in Galway, Ireland. My hosts were Stefan Decker, the director of the lab, and John Breslin who is heading the SIOC project.

DERI has become the world's premier research institute for the Semantic Web. Everyone working in the field should know about them, and if you can, you should visit the lab to see what's happening there.

Part of the National University of Ireland, Galway. With over 100 researchers focused solely on the Semantic Web, and very significant financial backing, DERI has, to my knowledge, the highest concentration of Semantic Web expertise on the planet today. Needless to say, I was very impressed with what I saw there. Here is a brief synopsis of some of the projects that I was introduced to:

• Semantic Web Search Engine (SWSE) and YARS, a massively scalable triplestore.  These projects are concerned with crawling and indexing the information on the Semantic Web so that end-users can find it. They have done good work on consolidating data and also on building a highly scalable triplestore architecture.
• Sindice -- An API and search infrastructure for the Semantic Web. This project is focused on providing a rapid indexing API that apps can use to get their semantic content indexed, and that can also be used by apps to do semantic searches and retrieve semantic content from the rest of the Semantic Web. Sindice provides Web-scale semantic search capabilities to any semantic application or service.
• SIOC -- Semantically Interlinked Online Communities. This is an ontology for linking and sharing data across online communities in an open manner, that is getting a lot of traction. SIOC is on its way to becoming a standard and may play a big role in enabling portability and interoperability of social Web data.
• JeromeDL is developing technology for semantically enabled digital libraries. I was impressed with the powerful faceted navigation and search capabilities they demonstrated.
  
• notitio.us. is a project for personal knowledge management of bookmarks and unstructured data.
• SCOT, OpenTagging and Int.ere.st.  These projects are focused on making tags more interoperable, and for generating social networks and communities from tags. They provide a richer tag ontology and framework for representing, connecting and sharing tags across applications.
• Semantic Web Services.  One of the big opportunities for the Semantic Web that is often overlooked by the media is Web services. Semantics can be used to describe Web services so they can find one another and connect, and even to compose and orchestrate transactions and other solutions across networks of Web services, using rules and reasoning capabilities. Think of this as dynamic semantic middleware, with reasoning built-in.
• eLite. I was introduced to the eLite project, a large e-learning initiative that is applying the Semantic Web.
• Nepomuk.  Nepomuk is a large effort supported by many big industry players. They are making a social semantic desktop and a set of developer tools and libraries for semantic applications that are being shipped in the Linux KDE distribution. This is a big step for the Semantic Web!
• Semantic Reality. Last but not least, and perhaps one of the most eye-opening demos I saw at DERI, is the Semantic Reality project. They are using semantics to integrate sensors with the real world. They are creating an infrastructure that can scale to handle trillions of sensors eventually. Among other things I saw, you can ask things like "where are my keys?" and the system will search a network of sensors and show you a live image of your keys on the desk where you left them, and even give you a map showing the exact location. The service can also email you or phone you when things happen in the real world that you care about -- for example, if someone opens the door to your office, or a file cabinet, or your car, etc. Very groundbreaking research that could seed an entire new industry.

In summary, my visit to DERI was really eye-opening and impressive. I recommend that major organizations that want to really see the potential of the Semantic Web, and get involved on a research and development level, should consider a relationship with DERI -- they are clearly the leader in the space.

A Universal Classification of Intelligence

I've been thinking lately about whether or not it is possible to formulate a scale of universal cognitive capabilities, such that any intelligent system -- whether naturally occurring or synthetic -- can be classified according to its cognitive capacity. Such a system would provide us with a normalized scientific basis by which to quantify and compare the relative cognitive capabilities of artificially intelligent systems, various species of intelligent life on Earth, and perhaps even intelligent lifeforms encountered on other planets.

One approach to such evaluation is to use a standardized test, such as an IQ test. However, this test is far too primitive and biased towards human intelligence. A dolphin would do poorly on our standardized IQ test, but that doesn't mean much, because the test itself is geared towards humans. What is needed is a way to evaluate and compare intelligence across different species -- one that is much more granular and basic.

What we need is a system that focuses on basic building blocks of intelligence, starting by measuring the presence or ability to work with fundamental cognitive constructs (such as the notion of object constancy, quantities, basic arithmetic constructs, self-constructs, etc.) and moving up towards higher-level abstractions and procedural capabilities (self-awareness, time, space, spatial and temporal reasoning, metaphors, sets, language, induction, logical reasoning, etc.).

What I am asking is whether we can develop a more "universal" way to rate and compare intelligences? Such a system would provide a way to formally evaluate and rate any kind of intelligent system -- whether insect, animal, human, software, or alien -- in a normalized manner.

Beyond the inherent utility of having such a rating scale, there is an additional benefit to trying to formulate this system: It will lead us to really question and explore the nature of cognition itself. I believe we are moving into an age of intelligence -- an age where humanity will explore the brain and the mind (the true "final frontier"). In order to explore this frontier, we need a map -- and the rating scale I am calling for would provide us with one, for it maps the range of possible capabilities that intelligent systems are capable of.

I'm not as concerned with measuring the degree to which any system is more or less capable of some particular cognitive capability within the space of possible capabilities we map (such as how fast it can do algebra for example, or how well it can recall memories, etc.) -- but that is a useful second step. The first step, however, is to simply provide a comprehensive map of all the possible fundamental cognitive behaviors there are -- and to make this map as minimal and elegant as we can. Ideally we should be seeking the simplest set of cognitive building blocks from which all cognitive behavior, and therefore all minds, are comprised.

So the question is: Are there in fact "cognitive universals" or universal cognitive capabilities that we can generalize across all possible intelligent systems? This is a fascinating question -- although we are human, can we not only imagine, but even prove, that there is a set of basic universal cognitive capabilities that applies everywhere in the universe, or even in other possible universes? This is an exploration that leads into the region where science, pure math, philosophy, and perhaps even spirituality all converge. Ultimately, this map must cover the full range of cognitive capabilities from the most mundane, to what might be (from our perspective) paranormal, or even in the realm of science fiction. Ordinary cognition as well as forms of altered or unhealthy cognition, as well as highly advanced or even what might be said to be enlightened cognition, all have to fit into this model.

Can we develop a system that would apply not just to any form of intelligence on Earth, but even to far-flung intelligent organisms that might exist on other worlds, and that perhaps might exist in dramatically different environments than humans? And how might we develop and test this model?

I would propose that such a system could be developed and tuned by testing it across the range of forms of intelligent life we find on Earth -- including social insects (termite colonies, bee hives, etc.), a wide range of other animal species (dogs, birds, chimpanzees, dolphins, whales, etc.), human individuals, and human social organizations (teams, communities, enterprises). Since there are very few examples of artificial intelligence today it would be hard to find suitable systems to test it on, but perhaps there may be a few candidates in the next decade. We should also attempt to imagine forms of intelligence on other planets that might have extremely different sensory capabilities, totally different bodies, and perhaps that exist on very different timescales or spatial scales as well -- what would such exotic, alien intelligences be like, and can our model encompass the basic building blocks of their cognition as well?

It will take decades to develop and tune a system such as this, and as we learn more about the brain and the mind, we will continue to add subtlety to the model. But when humanity finally establishes open dialog with an extraterrestrial civilization, perhaps via SETI or some other means of more direct contact, we will reap important rewards. A system such as what I am proposing will provide us with a valuable map for understanding alien cognition, and that may prove to be the key to enabling humanity to engage in successful interactions and relations with alien civilizations as we may inevitably encounter as humanity spreads throughout the galaxy. While some skeptics may claim that we will never encounter intelligent life on other planets, the odds would indicate otherwise. It may take a long time, but eventually it is inevitable that we will cross paths -- if they exist at all. Not to be prepared would be irresponsible.

A Bottle That Purifies Enough Water for a Year

This is a really great invention -- a hand held water bottle that can purify a year's worth of water. It removes not only parasites and bacteria, but also viruses. It was just announced recently at a defense industry tradeshow and was a big hit among military commanders who need a better way to get water to their troops. Beyond that it could be a lifesaver in disaster areas and in developing countries where finding clean water is a daily struggle.

New Photon Thruster: Get to Mars in 1 Week!

An interesting new patent pending design for a photon thruster appears to be the real deal. Check out the article and who is behind it. (A fellow SRI alumnus!). Getting to Mars in a week means getting to the moon, as well as other nearby planets would be quite fast as well. This could be quite revolutionary.

TUSTIN, Calif., Sept. 7, 2007 -- An amplified photon thruster that could potentially shorten the trip to Mars from six months to a week has reportedly attracted the attention of aerospace agencies and contractors.

Young Bae, founder of the Bae Institute in Tustin, Calif., first demonstrated his photonic laser thruster (PLT), which he built with off-the-shelf components, in December.

DBpedia.org is Among the Coolest Semantic Web Datasets I've Seen

I've been poking around in the DBpedia, and I'm amazed at the progress. It is definitely one of the coolest (launched) example of the Semantic Web I've seen. It's going to be a truly useful resource to everyone. If you haven't heard of it yet, check it out!

Russian Scientists Discover Radiation Absorbing Mineral

Russian scientists in the Khibinsky Mountains in the Arctic Circle have made an important scientific discovery. They've found a new mineral which absorbs radiation.     It does not yet have an official name and is known only as number 27-4. It can absorb radioactivity from liquid nuclear waste.

Burning Salt Water -- A New Form of Fuel

Inventor, John Kanzius, has figured out a way to burn salt water. This could provide a clean, naturally available alternative fuel source. Salt water is one of the most abundant natural resources on our planet. Here's a video.

Virtual Out of Body Experiences

A very cool experiment in virtual reality has shown it is possible to trick the mind into identifying with a virtual body:

Through these goggles, the volunteers could see a camera view of their own back - a three-dimensional "virtual own body" that appeared to be standing in front of them.

When the researchers stroked the back of the volunteer with a pen, the volunteer could see their virtual back being stroked either simultaneously or with a time lag.

The volunteers reported that the sensation seemed to be caused by the pen on their virtual back, rather than their real back, making them feel as if the virtual body was their own rather than a hologram.

Volunteers

Even when the camera was switched to film the back of a mannequin being stroked rather than their own back, the volunteers still reported feeling as if the virtual mannequin body was their own.

And when the researchers switched off the goggles, guided the volunteers back a few paces, and then asked them to walk back to where they had been standing, the volunteers overshot the target, returning nearer to the position of their "virtual self".

This has implications for next-generation video games and virtual reality. It also has interesting implications for consciousness studies in general.

Scientist Says "Never in Our Imagination Could This Happen." Famous Last Words?

Whenever a scientist says something like, don't worry our new experiment could never get out of the lab, or don't worry the miniature black hole we are going to generate couldn't possibly swallow up the entire planet, I tend to get a little worried. The problem is that just about every time a scientist has said something is patently absurd, totally impossible or could never ever happen, it usually turns out that in fact it isn't as impossible as they thought. Now here's a new article about scientists creating new artificial lifeforms, based on new genetic building blocks -- and once again there's one of those statements. I'm guessing that this means that in about 10 years some synthetic life form is going to be found to have done the impossible and escaped from the lab -- perhaps into our food supply, or maybe into our environment. Don't get me wrong -- I'm in favor of this kind of research into new frontiers. I just don't think anyone can guarantee it won't escape from the lab.

Axons Process Information

I just heard about a very interesting new discovery in neuroscience:. The basic gist is that it appears that axons process information. Until now it has been thought that only the cell body of neurons was the part that processed information. Our present understanding of the brain, and also of psychopharmacology, is based completely on the dendrites and main body of the neuron. If it turns out that axons -- the "wires" that connect neurons -- are actually major contributors to how the brain computes, then it may point to both a new understanding of cognition, as well as a new frontier in treating mental and neurological disorders. (Thanks to Bram for letting me know).
