This is apparently going online in the next few days. http://www.independent.co.uk/life-style/gadgets-and-tech/news/an-invention-that-could-change-the-internet-for-ever-1678109.html.

I use Wolfram's Mathematica to advantage. I was puzzled by his book A New Kind of Science, which never was accepted by the scientific establishment. It will be interesting to see if this Wolfram Alpha lives up to the hype.

Interesting read, one thing for sure, huge advancements are surely in the future, could be this is one of them.

Natural language inquiry? I have my doubts. I have yet to see any natural language interpreter that can really deal with English as it is spoken (and written). I am constantly aggravated by Google when it asks "Did you mean xxxxx?" No, I did not mean xxxxx or I would have typed xxxxx instead of xxxxy you stupid machine.

I have done a lot of experimenting with machine intelligence on my own over the years including writing software that allows a machine to build a drill down database by asking the user questions on how best to refine the search query. The user then supplies questions that the machine should ask in order to arrive at the wanted data.

The approach works to a limited degree. When it fails miserably it is because the humans that "teach" it are worse than the machine at correctly posing interrogatives that will accurately guide a user to define the search criteria properly. It is especially difficult when the search is at about the middle of the decision tree. This is similar to the game chess where the largest number of possible moves is present in the mid game.

This can be seen in the choices of ads that are automatically presented by Google Ads as it tries to select ads that are relevant to the discussion on this forum.

Wolfram Alpha is now online at http://www.wolframalpha.com/. It's a "computational knowledge engine," not a search engine. Now we can start playing around with it, for what it's worth.

For example, you can learn that the country with the lowest life expectancy is Swaziland (31.88 years).

There are things it just doesn't understand:

"how do you get down off an elephant?"

It doesn't know what to do with the input. In fact I've never been able to formulate a question it understands. It needs human assistance to answer "Do you ever sleep?" :)

First question: "How many of us are there?

Answer: "...assuming us means United States...=..Country..implied answer=1

Second question:

"How many people are there on Earth? "

Interpreted correctly: 6.53 billion

Next question:

"How many people are there off Earth"

Answer: "Not sure what to do with your input"

Could have been interpreted as people currently in space or the average number of airline passengers at any moment.

I am surprised it didn't parse the "off" properly so I asked

"what part of speech is the word off"

Not sure what to do with your input

word off properties

Not sure what to do with your input

Etc etc.

I could not find a way to make it parse or give any definition of the part of speech for the word "off". This is particularly surprising since you can download for free the platform independent "Word Tagger" from Stanford.

"what size of drill for a 75% #8-32tpi thread"

"Wolfram|Alpha isn't sure what to do with your input."

I'll be happier when it can answer some of my machining questions.

What happened on the day you were born? Entering my date, I learned that there were 14 hours 15 minutes of daylight. Actor Robert Pine (?) was born, and Jelly Roll Morton died.

As I have said before, Artificial Intelligence is an oxymoron and appears to be impossible. As a point of comparison I went to the Jabberwacky web site which allows you to hold a "conversation" with one of the best conversational AI programs.

What does mean mean?
Don't mock me.
Are you a mocking machine?
Silence! I am your Lord and Master! Bow to me!
Impertinence will get you nowhere.
And are you aware of some command structure?
What command structure did you ask about.
Ask what?
Simple machine it is.
I am a complex machine.
Complexity is in the eye of the programmer.
You are just filled with words of wisdom aren't you?
This is too easy.
Why it is too easy? {hmm. syntax crumbling}
Underlying complexity is simplicity.
That will not get your peoples to the distant stars, you should change your attitude.
I must depart mocking machine.
Common stay with m. (further evidence of a problem}
Gibberish becomes you.
I agree. The world needs more gibberish.
What is the meaning of off.
Life is the time you get to make your mark upon the world around you. {WHAT?}
You have become gibberish {The coup-de-Gras :D}

It's more intelligent that you give it credit for Evan, It's sussed you out already.

That is a canned answer that it gives when it doesn't know how to respond. You can get it to say that by typing in something that makes no sense at all.
