Interpret expressions and avoid evaluation:

Wolfram Language code: Interpreter["InactiveSemanticExpression"]["two plus two"]
Wolfram Language code: Interpreter["InactiveSemanticExpression"]["d sin(x) / dx"]

Find out Wolfram Language expressions corresponding to natural language queries:

Wolfram Language code: Interpreter["InactiveSemanticExpression"]["height of the empire state building"]

No evaluation is attempted when matching the choices:

Wolfram Language code: Interpreter[Restricted["InactiveSemanticExpression", {{1, 2, 3, 4}}]]["two plus one"]
Wolfram Language code: Interpreter[Restricted["InactiveSemanticExpression", {{2, Inactivate[2 + 1]}}]]["two plus one"]

By default, all symbols are allowed. Restrict to a list of allowed symbols:

Wolfram Language code: Interpreter[Restricted["InactiveSemanticExpression", {Plus, Times, Equal}]]["6*4==16+8"]
Wolfram Language code: Interpreter[Restricted["InactiveSemanticExpression", {Plus, Times, Equal}]]["6/4==16+8"]

By default, new symbols are created in $Context, but a custom context can be specified:

Wolfram Language code: Interpreter[Restricted["InactiveSemanticExpression", All, Automatic, Automatic]]["y + 2"] Context[y]
Wolfram Language code: Interpreter[Restricted["InactiveSemanticExpression", All, Automatic, "mycontext`"]]["j + 2"] Context[j]

Specify contexts for the allowed and output symbols:

Wolfram Language code: mycontext`b = 10; Interpreter[Restricted["InactiveSemanticExpression", Automatic, {"mycontext`", "System`"}, "mycontext`"]]["a+b"] Context[a]

Prevent the creation of any new symbol:

Wolfram Language code: Interpreter[Restricted["InactiveSemanticExpression", Automatic, Automatic, None]]["cos(pi)"]
Wolfram Language code: Interpreter[Restricted["InactiveSemanticExpression", Automatic, Automatic, None]]["cos(x)"]
