Wolfram Alpha Opens API, More Features on the Way

Michael Manoochehri, May 26th, 2009

Wolfram Alpha As far as web search tools go, few have generated as much hype as Wolfram Alpha. The service, which bills itself as a “computational knowledge engine,” differs from search engines such as Google, in that it does not return lists of web pages. Rather, Wolfram Alpha attempts to calculate answers to user queries. For example, a query of “los angeles county median household income” will return the result “$43,518.”

Access to Wolfram Alpha’s computational search results are provided via a RESTful “Query” API, which allows developers to submit query strings, much like users do at the Wolfram Alpha website. Because Alpha has limited language processing capabilities, it cannot parse every query string it receives, so developers can choose to first have their query strings checked to see if Alpha can handle the format of the question. The Query API has many features, such as the ability to request location specific information, or the ability to set the default return currency for economic queries. More details at our Wolfram Alpha API profile.

CNET’s Stephen Shankland describes the potential power of Alpha’s API:

There’s an API for Alpha that could help the service catch on. It’s a mashup expert’s dream, and the fact that Wolfram licenses data not publicly available, then vets it to boot, means a lot of people will be willing to incorporate it on their Web sites.

Wolfram Alpha’s Query API also provides very powerful return formats: Queries can be returned in text formats such as MathML, Mathematica, plain text and more. Alpha can also return queries as images in Gif, PDF, or HTML formats. In order to use the Wolfram Alpha Query API, developers are required to obtain a development key (see this page).

In the future, Wolfram Alpha plans to release a more detailed API (called the “Data” API) which will allow developers to have more control over the data sets used in the query result. Wolfram Alpha’s API documentation describes the upcoming Data API:

Wolfram|Alpha has a simple yet expressive internal mechanism for extracting specific pieces of data from its enormous store of curated data. In the near future we will be exposing this facility via a web API. This type of request can be used when you want a single result value or set of values and can describe the data you want in a precise way (or at least ask Wolfram|Alpha to assist you in determining the correct way to ask).

Wolfram Alpha claims to have a “trillions” of pieces of data in its database, which might make it the most comprehensive semantic search engine available. However, Alpha is not the only semantic search that offers an API. True Knowledge, another natural language query engine which we’ve recently covered, differs from Wolfram Alpha in that it focuses on returning user queries in a human readable style. While True Knowledge’s servers might not have access to the huge amount of data that Alpha does, developers may appreciate the user-friendly query results.

1. The name is not friendly and selfish.
2. The interface is not friendly either.

Hey, interesting article about Wolfram Alpha. Seems like a fascinating product. Just found another good article about it and its potential as a rival to google on http://www.dimnetblog.blogspot.com Worth a read.

That’s all nice.

But how comes, you are talking about API, which seems that it doesn’t work, or it’s down?

Of course I applied for a dev api key, but nothing received yet, and also the API URL, stated in their docs, is down as downs: api.wolframalpha.com

I tried that from various locations (US, UK, EU).

The only thing I found, regarding the API is: http://community.wolframalpha.com/story.php?title=api-key-request

but up today, no answer, no reaction.

Can someone please update, if the API works for him, or at least can we get some update on when/how we’ll be able to start using it, if articles like this just saying that everything is ok, but obviously it is not.

Thank you.
Kersha

Hi all,

Russ here from the WolframAlpha team…

The Wolfram Alpha API will be released in late august/early september.

Some preview access is available.

Please contact us via various forms at WolframAlpha.com if you’re interested, want information, have a killer app idea… or whatever else strikes you.

We will have a developer site up and running in the next month or so as well.

Thanks!

Comment by: Damian Campbell 37 Critical Items

On this Sold Out After Crisis Assessment and commentary, you will learn about
a set of guides that can prepare you for almost any catastrophe that
might be headed our way, regardless of whether it’s a hurricane, a flood, a terrorist assault, earth war
III, or an more and more additional most likely economical
collapse.

Damien Campbell is a survival specialist that has expended years studying
survival topics which include long-term foods storage,
h2o purification procedures, different sources of energy, unexpected emergency medicine,
and yard gardening. When he began scripting this tutorial, he started out by making a record of meals
to stock up on. The issue was that list was pretty extended,
and some of your food items had been hard to retailer.
While in the curiosity of holding his tutorial so simple as attainable, he narrowed the
past right down to 37 vital foods things that everybody order now previously it’s too late.

Unfortunately, the typical American has no strategy how bad issues definitely are.
The media want to pretend almost everything is alright, but
in fact, we face a lot more risk now than now we have in many years.
Farmers are working outside of acreage, outdated sources of consuming h2o
are drying up, terrorists are more common than previously, and deficit shelling out is draining our financial system
and could conveniently lead to hyperinflation.

That’s why it is so crucial for being ready. For those who hold out right until the crisis is at your step,
will probably be as well late mainly because by then,
the public will have emptied the outlets. A good deal of folks don’t know this,
but grocery shops only maintain 3-4 times price of food items available.
And when disasters strike, that food items is gone
in just 3-4 several hours! It is took place many times previously.
