Variables with a limited number of options use a pull-down interface these elements include the current attribute to indicate which option is currently active and the count attribute to indicate how many options are available. Įach variable used in the formula has its own element with unique name and desc attributes. It has two attributes: name, the internal name of the formula, and desc, the descriptive name used for display purposes. This element is the outer wrapper for the formula. The following is a brief summary of formula-related XML elements returned by the Fast Query Recognizer API, along with the standard attributes for each.
The Instant Calculators API allows you to recreate this functionality with structured XML that can be easily embedded into web deployments: &input=RAID+array &assumption=FSelect_**RAIDArray- &assumption=*FP.RAIDArray.RAIDLevel-_RAID6 &assumption=*F.RAIDArray.disks-_2 &assumption=*F.RAIDArray.size-_500+GB Formula XML Elements For example, the "RAID array" query yields the following user interface:Īdjusting the options in this form allows the user to calculate the total storage capacity for various RAID configurations. Many Wolfram|Alpha queries generate simple interfaces for exploring equations, formulas and other information using pull-down menus and fillable text fields. The sections below give more detail on using formula assumptions. The assumptions listed in this result correspond directly to the XML elements given in the Fast Query Recognizer API response: īase-2 RAID capacity | 465.7 GiB (gibibytes) This URL will return an XML form with the resulting value, along with elements for further calculations. For instance, here is a query that uses the FormulaSelect assumption to evaluate the RAIDArray formula with default input values: ?appid=DEMO &input=RAID+array &assumption=FSelect_**RAIDArray. The rest of the URL uses formula assumptions (described below) to specify values for each variable.

The base URL for the Full Results API is: Īs before, this query requires an App ID and an input value (using the input parameter): ?appid=DEMO &input=RAID+array Now, using these variable names, you can build a Full Results API query to calculate a specific value.
When executed with a valid AppID, this URL will return an XML form with input elements for calculating the properties of a RAID array: For instance, here is a query for "RAID Array": queryrecognizer/ query.jsp? appid=DEMO& mode=Default & i=RAID+array Next, use the i parameter to specify the URL-encoded input for your query. For the purposes of this sample query, we'll use the "Default" mode: queryrecognizer/ query.jsp? appid=DEMO & mode=Default The Fast Query Recognizer has two distinct modes, "Default" and "Voice", explained below. The appid parameter tells your query which AppID to use: queryrecognizer/ query.jsp ? appid=DEMO The base URL for queries is: queryrecognizer/ query.jspĮvery query requires three pieces of information-an AppID, a mode and an input value-in order to be processed correctly. Now that you have an AppID, you can make your first query. The base URL for the Fast Query Recognizer API is: Start with a Fast Query Recognizer API request to retrieve the information for a particular formula. Using the Instant Calculators API Sample Query
