Wolfram Alpha

[bascule]

So Stephen Wolfram, creator of Mathematica, is about to release a search engine for formal knowledge based on Mathematica:

 

http://www.twine.com/item/122mz8lz9-4c/wolfram-alpha-is-coming-and-it-could-be-as-important-as-google

 

The idea is they'll hand curate a formal knowledge database about science, technology, geography, weather, cooking, business, travel, people, music, etc. and from this Mathematica will be able to apply rich calculations to answer natural language questions.

 

It will be interesting to see how well this works.

yeah i'm pretty excited about this. Any guesses about how the thing works?

 

I bet they're just hooking up Wolfram's brain to a motherboard.

Any guesses about how the thing works?

 

I would guess it contains a logic language similar to Prolog for performing queries across formally specified relations between different knowledge systems.

Some people have pointed out MIT's START as an existing alternative:

...however I'm terribly underimpressed. START is unable to answer fairly basic biology questions like "Are humans mammals?"

 

I sure hope Wolfram Alpha will be able to answer those kinds of questions...

[Mr Skeptic]

Nice. I sure hope this works as advertised.

Wolfram Alpha launches on Tuesday. ReadWriteWeb did a review of it, and their take was quite positive:

I expect this will become a rather useful tool for scientists and mathematicians alike (not to mention the general public)

Tuesday as in 5.5?

[bascule]

Looks like they're only giving out early access to certain people today. The site will launch officially to the public in May.

It's happening! Check it out:

My feelings would best be described at surprised, meant in both the positive and negative way. While there are a lot of things that are infinitely cool, such as when you type in a mathematical problem, say [math] \frac{d}{dx} sin(x) + cos(x)[/math] you can ask it to show you the steps it took to arrive at the result, not just the result, although I'm not sure it works for every single computation.

Another is the extent of data available in certain areas. For example, I was astounded to find out that it had weather records dating back nearly 70 years for the town I live in (Pisek; population of 30k, in the middle of nowhere, South Czech Republic). And it certainly doesn't end there.

 

However, I was also disappointed by the lack of information in certain areas. For example, if you type in complex plane, or ferrofluid, it hasn't got a clue what you're talking about. Another one, if you type in "life expectancy male age 17 in Czech Republic", it gives you result, but add "smoker", and it's speachless.

If you type in "smoker male age 17" it gives you lots of graphs, LDL cholesterol ammount, systolic BP and whatnot. But replace "smoker" with "heroin addict", or "drug user", or just "drug", and it just doesn't know. Same with "heroin addicts in USA" or "drug users in USA".

Another one, if you type in "distance from Pisek to Sacramento", it gives you a result. But if you type in "distance from Pisek to Sacramento / 5 mph" it gives you a fraction with empty spaces (no result). If you type in "distance from Pisek to Sacramento at 5 mph" it won't give you a result. But if you type "pisek to sacramento at 5 mph", it will give you a result.

Another example, if you type in "number of males", it gives you a result, with plots and everything, but if you type in "number of females", it will interpret "female" as a physical quantity and give you nothing. To get the result, you need to type in "female population in all countries", or a suitable variation of that. And for that last one, I'm just waiting for some hardcore feminists to make an issue out of it (no offense intended).

You'll also experience a lot of server overload errors if you try it out now, but that's to be expected, and I'm actually pretty impressed at how well it's holding up under the strain. They say they'll have the whole cluster up and running at the end of the weekend, and we should experience any problems after that.

 

Anyway, as S. Wolfram said, this is just the beginning, and I'm confident that its repository of knowledge is going to grow fast. And even if it won't, I'll still consider May 15th 2009 a pivotal day in human history. So much data, and all of it is just a couple of keystrokes away.

 

As a PS, a Wolfram Alpha Toolbar is available for FF and IE, along with other gadgets. Check the download section on the site, and ENJOY!!

WolframAlpha definitely needs improvements. The response to my question, "Where is Osama Bin Laden?" wasn't anywhere near sufficient. So much for "predicting" the answers

[Shadow]

It never said it would predict the answers, it said it would compute them from the data at hand. Although it would be nice to be able to ask it "What is the probability of bin Laden being in Paris at 1650 tomorow?" In other words, it'd be nice to have Spock on a web page...

 

Wolfram|Alpha, as it exists today, is just the beginning. We have both short- and long-term plans to dramatically expand all aspects of Wolfram|Alpha, broadening and deepening our data, our computation, our linguistics, our presentation, and more.

 

Wolfram|Alpha is built on solid foundations. And as we go forward, we see more and more that can be made computable using the basic paradigms of Wolfram|Alpha—and a faster and faster path for development as we leverage the broad capabilities already in place.

I've been kind of disappointed with it so far... it wasn't what I was expecting. Also it's been broken a lot...

[Mr Skeptic]

I think it's mostly intended for math, and the attempts at language are simply lacking.

[insane_alien]

i like it, its useful for getting some quick figures. i think its going to be one of those projects that takes a while to get really amazing, needs to amass a large amount of data before then and thats going to take a while.

[Shadow]

That's my view as well. Although I admit it does get frustrating at times, I'm still impressed.

WA didn't manage that one either.

[bascule]

WA didn't manage that one either.

 

Nope, which is disappointing

[Mr Skeptic]

Nope, if you ask WA whether humans are mammals, it doesn't know how to answer. However, WA knows the scientific classification of humans, including that they belong to Mammalia.

Wolfram is giving away most stuff on the Raspberry Pi platform. The idea is to really kindle interest in the educational domain

Whenver I use Wolfram Alpha I get nostalgic for Eric's Treasure Trove of Mathematics.

 

Crazy pre-Wikipedia days.

There is a new Wolfram project for simplifying programming among other things. >>Wolfram Cloud
