#### How does Wolfram|Alpha deal with linguistic ambiguity?

It ranks possible interpretations, gives results for the one it thinks is most plausible and gives links to click to get other ones. It often uses your location to rank interpretations—say, favoring cities that are near you.

#### When Wolfram|Alpha prompts for input, what can I enter?

Pretty much anything you could put into the main Wolfram|Alpha input field. For instance, if you're asked for a density, you can either give an explicit number or a response like "water".

#### Will I always get the same answer to a particular question?

Usually, but not necessarily. Some results may depend on the time and/or location of the query. In addition, Wolfram|Alpha is continually being updated and enhanced.

#### How does Wolfram|Alpha know where I am located?

It uses GeoIP, tracing back from the IP address it picks up when your browser contacts the Wolfram|Alpha server. The location it deduces should be correct to within about five miles. You can also set a specific location in the "Preferences" tab of the user drop-down menu in the top-right corner of Wolfram|Alpha pages.

#### Why does Wolfram|Alpha use the wrong location for me?

Wolfram|Alpha deduces your location from your IP address. If you are using a VPN, satellite internet or some other complex form of network, you may have to correct your location explicitly by including it in your input or by setting a specific location in the "Preferences" tab of the user drop-down menu in the top-right corner of Wolfram|Alpha pages.

#### How can I tell Wolfram|Alpha my location?

Wolfram|Alpha should automatically know your approximate location from GeoIP. If for some reason it does not, you can include a city or latitude, longitude specification in your input.

#### How can I tell whether Wolfram|Alpha covers a particular area?

The easiest thing to do is just to try a simple case of it. You can also browse the Examples by Topic page, or ask on Wolfram Community.

#### What are Wolfram|Alpha's main limitations?

It can only know things that are known, and are somehow public. It only deals with facts, not opinions. It limits the computation time for each query. And, of course, it's in continual development—and always will be.

#### In what areas is Wolfram|Alpha strongest?

We've first emphasized areas where computation or mathematics have traditionally had a more significant role, or where knowledge is more readily quantitative. But we're steadily working through all the content areas covered by reference libraries, handbooks and much more.

#### How much math can Wolfram|Alpha do?

Pretty much anything that's possible using today's best algorithms—subject only to the constraint that the computations must complete in the time Wolfram|Alpha has available.

#### Can Wolfram|Alpha do higher math?

Yes, absolutely. It has access to all of Wolfram Language's algorithms, which cover algebra, calculus, geometry, number theory, discrete math and much more.

#### Does Wolfram|Alpha cover what is in standard math handbooks?

Yes, quite thoroughly, including everything in standards like Abramowitz & Stegun, Gradshteyn & Rhyzik and many, many others. It covers much that isn't in such books, as well. And because Wolfram|Alpha performs real-time computations rather than simply looking up data, it can always derive new results.

#### Does Wolfram|Alpha cover what is in handbooks of chemistry and physics?

Yes, fairly thoroughly. And it's not just able to look up tabulated values, but also to compute from empirical formulas and so on, and to use such results as inputs to other computations.

#### How broad is Wolfram|Alpha's coverage of socioeconomic data?

For data that's systematically available internationally, its coverage is quite broad. There's more to do on data that's specific to particular countries.

#### Does Wolfram|Alpha have real-time financial data?

Yes. Wolfram|Alpha gives the latest trade quotes in real time.

Basic computable information about well-known people, such as birth and death dates, government positions, major awards, etc. More data and connections are being added.

#### How much data does Wolfram|Alpha have on popular culture?

Basics, particularly about more computable issues, such as movie box-office grosses. More is being added.

#### Why doesn't Wolfram|Alpha have data on a particular domain?

Most likely because we haven't gotten to it yet. Feel free to contact us with contributions or suggestions of data that we should include.

#### How much data is there in Wolfram|Alpha?

Many trillions of elements, continually growing through a large number of feeds.

#### Does Wolfram|Alpha get its data from the web?

No. It comes from Wolfram|Alpha's internal knowledgebase. Some of the data in that knowledgebase is derived from official public or private websites, but most of it is from more systematic primary sources.

#### Where does Wolfram|Alpha's data come from?

Many different sources, combined and curated by the Wolfram|Alpha team. At the bottom of each relevant results page there's a "Sources" button, which provides background sources and references.

#### Can I find the origin of a particular piece of data?

Most of the data in Wolfram|Alpha is derived by computations, often based on multiple sources. A list of background sources and references is available via the "Sources" button at the bottom of relevant Wolfram|Alpha results pages.

#### How is Wolfram|Alpha's data checked?

We use a portfolio of automated and manual methods, including statistics, visualization, source cross-checking and expert review. With trillions of pieces of data, it's inevitable that there are still errors out there.

#### How often is the data in Wolfram|Alpha updated?

Many kinds of data—such as financial or weather—stream in all the time. Other kinds of data are updated when they become available, on a daily, weekly, monthly or yearly basis.

#### What should I do if I find an error in Wolfram|Alpha's data?

Tell us! We're always working hard to perfect the quality of our data.

#### How may I use data from Wolfram|Alpha?

You can use individual pieces of data however you want. There are, however, restrictions on aggregate uses, as described in the Terms of Use. Please contact us if you're wondering about a particular use.

#### Does Wolfram|Alpha stand behind the data it uses?

Yes. Although we must rely on external sources for many kinds of raw data, we curate all data and our goal is to make sure that it is perfect.

#### How is real-time data curated?

Wolfram|Alpha effectively checks real-time data (such as weather, earthquakes, market prices, etc.) against built-in criteria and models. If an unexpected deviation is found, Wolfram|Alpha will normally indicate it, for example by showing lines as dashed.

#### How much of Wolfram|Alpha's data comes from Wikipedia?

Most of the data comes directly from primary sources. However, Wikipedia contains excellent "folk information" about everyday practices in many domains, about the popularity and names of things (such as "the big apple" for NYC, and so on). Wolfram|Alpha uses such information especially for linguistic disambiguation.

#### What educational levels is Wolfram|Alpha suitable for?

Any level, from kindergarten to graduate school and beyond. On the elementary end, Wolfram|Alpha can do arithmetic showing steps, make clocks, work with colors and so on.

#### Should I cite Wolfram|Alpha when I use results from it?

Yes. For academic purposes, Wolfram|Alpha is a primary source.

#### How should I cite results from Wolfram|Alpha?

The citable author is Wolfram|Alpha. Don't forget to include the time and/or place at which the query was made, as it can affect the result. You can reference results in individual pods by giving their names. See standard citation elements for Wolfram|Alpha for specific elements and an example.

#### How can I find out what to cite when I use data from Wolfram|Alpha?

Wolfram|Alpha should be considered the source, just as an encyclopedia or other reference would be. If you include the Wolfram|Alpha URL in your document, your readers can go to the "Sources" button to get further references. Note that Wolfram|Alpha often combines and adapts data from multiple sources.

#### Is the content of Wolfram|Alpha peer reviewed?

Yes, the content is reviewed by domain experts. It is also extensively validated using automated testing. For external data, we strive to use the most reliable sources available.

#### Can I find out how specific results in Wolfram|Alpha were derived?

Elementary math results often have "Step-by-step solution" buttons, and combinations of data have "Details" buttons. "Sources" buttons give information on background sources for external data.

Wolfram Language. Without Wolfram Language's high-level symbolic programming and huge base of built-in algorithms, Wolfram|Alpha simply wouldn't have been possible.

#### What web technology does Wolfram|Alpha use?

Its server technology is based on Apache Web servers accessing clusters of webMathematica servers.

#### Does Wolfram|Alpha use an ontology?

In effect it has a dynamic algorithmic version of an ontology, implemented using symbolic programming. A future version of the Wolfram|Alpha API may expose some of Wolfram|Alpha's internal ontology constructs.

#### How does Wolfram|Alpha compare to search engines?

Search engines give you links to pages that exist on the web. Wolfram|Alpha computes answers to specific questions using its built-in knowledgebase and algorithms.

#### How does Wolfram|Alpha compare to Wikipedia?

Wikipedia gives you pages of narrative about topics. Wolfram|Alpha computes answers to specific questions you ask, just giving facts, not narrative. Wolfram|Alpha often includes sidebar links to Wikipedia.

#### What is the closest precursor to Wolfram|Alpha?

In concept, perhaps Leibniz's characteristica universalis from the late 1600s—or the science-fiction computers of the 1960s. Technologically, many pieces of Wolfram|Alpha have precursors, but the ambitious scope of the whole project is believed to be unique.

#### Does Wolfram|Alpha use artificial intelligence?

Not in a traditional sense. Wolfram|Alpha isn't mainly based on emulating human reasoning. Instead it uses powerful methods from science and algorithmic computation to get directly to answers.

#### Is Wolfram|Alpha an artificial intelligence?

It's much more an engineered artifact than a humanlike artificial intelligence. Some of what it does—especially in language understanding—may be similar to what humans do. But its primary objective is to do directed computations, not to act as a general intelligence.

#### Does Wolfram|Alpha use semantic web technology?

Not directly. Wolfram|Alpha has its own internal knowledgebase, with its own extensive internal semantics and ontology.

#### Does Wolfram|Alpha use natural language processing (NLP)?

Wolfram|Alpha introduces many new methods for understanding linguistic inputs. Mostly they're unlike traditional NLP, not least because Wolfram|Alpha has to deal with linguistic fragments rather than full grammatical sentences.

#### Can Wolfram|Alpha discover new facts?

Whenever it does new computations, it's effectively deriving new facts. At present, it always uses established scientific or other models as the basis for its computations. But using NKS it'll probably one day be possible for Wolfram|Alpha to discover new models too.

#### What is the theoretical foundation of Wolfram|Alpha?

Wolfram|Alpha attempts to synthesize all forms of knowledge that can be made computable—and uses methodology from all of them. A key general element is the concept of symbolic computation—inherited from the Wolfram Language system that underlies Wolfram|Alpha.

#### How does Wolfram|Alpha relate to NKS (Wolfram's A New Kind of Science)?
