✖

SemanticInterpretation["string"]

attempts to give the best semantic interpretation of the specified free-form string as a Wolfram Language expression.

✖

SemanticInterpretation["string",pattern]

filters possible semantic interpretations, returning the best one that matches the specified pattern.

✖

SemanticInterpretation["string",pattern,head]

returns the semantic interpretation wrapped with the specified head.

Details and Options

"string" can be natural-language English text.
Types of objects returned include numbers, formulas, Entity objects, DateObject, etc.
The following options can be given:

	AmbiguityFunction	Automatic	function to apply to the collection of possible interpretations
	GeoLocation	$GeoLocation	geo location to assume
	TimeZone	$TimeZone	time zone to assume for semantic interpretation
	Method	Automatic	which parser to use

If multiple interpretations are found, SemanticInterpretation supplies the list of them (with the best first) to the function specified as the setting for AmbiguityFunction. The result of applying that function is returned as the result from SemanticInterpretation.
By default, SemanticInterpretation uses the Wolfram|Alpha server. With the Method"LocalParse" option, the Wolfram|Alpha server will not be called unless no interpretation can be found.
