Tim Berners-Lee on Linked Data

via ted.com

Tim Berners-Lee, the inventor of HTTP, HTML and URLs, tells us about the genesis of the World-Wide-Web. Then Tim reminds us that there is still very little data available on the web. From there he explains that we need data relationships, what he calls Linked Data.

Wikipedia contains a lot of data. DBpedia extracts that data out of the text and make it available as Linked Data.

Governments around the world hold a lot of data, once this data becomes available, new services can emerge.

Lots of data is also in social networks, although it is still not liberated from services, i.e. it is not available as Linked Data.

Computers Understanding Humans?

via techcrunch.com

"... it understands and then computes answers to certain kinds of questions."

If what they claim is true, Wolfram Alpha may be the first usable technology that "understands" and that therefore I could accept as being an intelligent system.

This is not just a knowledge base. What Wolfram does is (to try to) understand a question in order to compute an (hopefully) accurate response based on knowledge available in built-in models.

The system is based on models meaning that it will be limited by the actual power of these models. Also it is designed to answer questions for which there is a consensus and factual answer.

It will not be able to give opinions about which social network is the best but it might be able to give a comparative GDP graph of 3 countries over a set period of time, much like an intelligent report generator could do.

The system is not a search engine although it might be able to provide sources related to its answers, in which case this would make it a very valuable tool.

I can't wait to be able to try it.
