How will the Seamntic Web address the fact that people lie?

Gianluca Angelici

I really agree about connections between ontologies. But it needs standardization of classes and properties described in owl. I could model the relationship "to work" in different ways: "work_at", "employee of", "developer at" or "consultant_at" etc.
And it shoul be indipendent from language. I'm Italian, and I could call this relationship in my language "lavora a".
So it should need an integration work that isn't so nice :-)
If we want a connected semantic web, we should create standard classes a props in owl (eg. like hcard in microformats). Something to extend where you need, but the least common multiple for everyone.
What do you think about it?

Excellent post.

Here's my input. The form of connection that I'm not seeing represented is that between people, not as individuals who network or have 'friends', but as both members of communities and participants of one type or another.

All the data on the web comes from people. If I'm searching for and accessing that data via a semantic facility, then I would think that my search results would be greatly enhanced by knowing more than only whether that data came from an individual (as opposed to an institution, private firm, etc.).

I haven't thought about how such information could be incorporated into a semantic relationship between packets structure, but do know that people contributing information are usually happy to identify their level of knowledge, expertise, interest and involvement, which self-identification options can be offered them in a variety of formats and situations.



What about intuitive connections with people Nova, especially regarding the Social Web? Surely this is a form of intelligence, that often goes unquantified and gets dismissed all too easily.

Regarding links: back about 12 years ago we built a software framework in the (then new) Java language named "Roku". Our ontology in Roku (Japanese for 'six') broke everything into one of six categories (Who, What, When, Where, Why and How).

In that implementation of our model we had semantic links between these granular objects (with meaning expressed in both directions). It was fully integrated with desktop applications (and Internet data) and broke up structured data into webs of semantically related objects.

One of the major issues we had was viewing these links between objects as individual entities in themselves. What we observed (in practice) was that links between objects happen in larger patterns (sets of links). We have since moved to patterns to hold the relationships between objects. Those patterns are classes in their own right and other objects only relate to the patterns. Our 'context engine' is the core of a project we are working on named indi. We pretty much hide all the semantics inside the platform, but folks will be able to feel it as they use it (oh, and we moved to Ruby in 2001).

I have really enjoyed your posts on this semantic web stuff. You have done a great job in explaining what can be a very arcane area. I look forward to checking out Radar when it launches.


You asked for other kinds of connections.

You've certainly covered all possible connections between people, information and applications, but what about other entities?

One that comes to mind is companies: What about links between companies, between people and companies, and companies and information?

That could be expanded to mean "group", as more informal groups than companies have the same kind of connections (and are sometimes better defined in today's web environment). Companies however have a certain status in the world - such as the right to own things (e.g. information) - which might set them apart.

Then again "a company" or "a group" are maybe not well defined as "objects" on the web today - and therefore wrong to say that these are connections currently found there?



Good points! One connection what I thing is coming important are location connections.

Nova's Trip to Edge of Space

  • Stepsedgestratosphere
    In 1999 I flew to the edge of space with the Russian air force, with Space Adventures. I made it to an altitude of just under 100,000 feet and flew at Mach 3 in a Mig-25 piloted by one of Russia's best test-pilots. These pics were taken by Space Adventures from similar flights to mine. I didn't take digital stills -- I got the whole flight on digital video, which was featured on the Discovery Channel.

Nova & Friends, Training For Space...

  • Img021
    In 1999 I was invited to Russia as a guest of the Russian Space Agency to participate in zero-gravity training on an Ilyushin-76 parabolic flight training aircraft. It was really fun!!!! Among other people on that adventure were Peter Diamandis (founder of the X-Prize and Zero-G Corporation), Bijal Trivedi (a good friend of mine, science journalist), and "Lord British" (creator of the Ultima games). Here are some pictures from that trip...


People I Like

  • Peter F. Drucker
    Peter F. Drucker was my grandfather. He was one of my principal teachers and inspirations all my life. My many talks with him really got me interested in organizations and society. He had one of the most impressive minds I've ever encountered. He died in 2005 at age 95. Here is what I wrote about his death. His foundation is at http://www.pfdf.org/
  • Mayer Spivack
    Mayer Spivack is my father; he's a brilliant inventor, cognitive scientist, sculptor, designer and therapist. He also builds carbon fiber trimarans in his spare time, and studies animal intelligence. He is working on several theories related to the origins of violence and ways to prevent it, new treatments for learning disabilities, and new theories of cognition. He doesn't have a Web site yet, but I'm working on him...
  • Marin Spivack
    Marin Spivack is my brother. He is the one of the only western 20th generation lineage holders of the original Chen Family Tai Chi tradition in China. He's been practicing Tai Chi for about 6 to 10 hours a day for the last 10 years and is now one of the best and most qualified Tai Chi teachers in America. He just returned from 3 years in China studying privately with a direct descendant of the original Chen family that created Tai Chi. The styles that he teaches are mainly secret and are not known or taught in the USA. One thing is for sure, this is not your grandmother's Tai Chi: This is serious combat Tai Chi -- the original, authentic Tai Chi, not the "new age" form that is taught in the USA -- it's intense, physically-demanding, fast, powerful and extremely deadly. If you are serious about Tai Chi and want to learn the authentic style and applications, the way it was meant to be, you should study with my brother. He's located in Boston these days but also travels when invited to teach master classes.
