Artificial Mediocrity, The Next Necessary Thing

This is a reply to a fantastic post named Artificial Stupidity: The Next Big Thing. by Nova Spivack.

In this post the author presents the following ideas:

  • He doubts that computers will be able to make intelligent decissions (comparing to humans).
  • We should concentrate mainly on low level thinking software (organizing, tagging, linking, remembering, etc.).
  • We should let humans making complex thinking, decission making, learning, teaching, problem solving, etc. etc.

The big point in this post lies in reducing our aims. Humans are working on AI since 1950s, and the Nexus 6 has not been built yet. And we are not going to build it soon.

I think most of people working with Semantic Web has this idea in mind. We don’t expect the web to sing Daisy Bell as HAL did, but perhaps humans are not so intelligent as Nova states, and computers could be smarter than he says.

I will follow the knowledge stairs.  (more…)

Playing with Ontologies for the GeoWeb II

Here we are again, with the second episode.

The first review was for a brand new, and ‘official’ ontology, GeoOWL. Now it’s the turn for the ontology of a popular free geospatial database, Geonames.

A great effort has been made to provide a graphical view of this ontology, dividing what is considered the core ontology, and the documents part.

Any critics or feedback will be much appreciate.

Geonames ontology review.

Playing with Ontologies for the GeoWeb I

This is the first, and I hope not the last post of a geospatial ontologies review series.

I’ve chosen GeoOWL to start, because it has been developed by W3C, and that means relevance, although it is more or less just a formalization of GeoRSS vocabulary.

Any critics or feedback will be much appreciate.

Zotero, the best research tool

Research activities involves a lot of tasks: reading articles, writing notes, searching for documents, web navigating, and, what is more important, Forget where you put the exact paper you need at this moment!

Zotero is a Mozilla Firefox plugin that can help you to deal with big amounts of information, documents, links, etc. Some of its most outstanding features by now:

  • Automatic capture of citations from web pages.
  • Store of PDFs, files, links and complete web snapshots.
  • A powerfool ‘as you type’ searching tool, which looks also inside PDF files.
  • Nice organization mechanisms, with directories or tags.
  • Great usability.
  • Integration with OpenOffice and MS Word and exportation facilities.

- So, It is perfect?

- Noooo!

- No? Why not?

Zotero doesn’t have an online storing server so far. The good news are that version 2.0 promises to give as this feature as a free present for all zotero lovers. You can read more about this plans in Zotero blog.

Exploring neighbourhood via outside.in

The list of location aware services grows every day. I have special interest on those services which aims at reducing the gap between human geospatial thinking and computer machine reasoning. I bring a nice example today, outside.in project.

An important percentage of worthwhile information for us is located near our home, or work place. That is our neighbourhood. But there exists a long distance between people who provide that information, and people who consume it. For instance, the street where we live could be closed for traffic because of an accident or for some repairs. Perhaps we are lucky and our council notifies to all citizens affected on time. Alice in wonderland. Most of times we’ll get notice when we take the car.

There are hundreds of examples: an special offer in our supermarket, a party in a bar near hour home, the birthday of hour neighbour, etc. etc. Sometimes interested people try to give us that information, but sometimes this is not posible. And this problem becomes bigger as the number of information sources also increases.

Outside.in project focuses on this problematic. They propose a web page where people can access information of their neighbourhood in an easy way, choosing the city + state, the neighbourhood and the city or just a zip code. Then you access to a map with the last news. Let’s see an example from Brookline neighbourhood, in Boston:

in.outside figure, from Brookline, Boston

And for information providers, the mechanism is easy. You have just to add your blog to Outside.in, and submit content to it directly from your blog. There are four ways to indicate that your post has an specific location:

  • Placing a link to a Google Map anywhere within a story.
  • A piece of content tagged with a zip code.
  • Using the where tag.
  • Using GeoRSS (obviously the best).

A great article talking about this idea.
But we have bad news, It’s designed just for the USA for the time being.We’ll have to wait (or we’ll have to develop) to see it in Europe.
