def language
  @language
end

#magnitude ⇒ Float (readonly)

A non-negative number in the [0, +inf] range, which represents the overall strength of emotion regardless of score (positive or negative). Unlike score, magnitude is not normalized; each expression of emotion within the text (both positive and negative) contributes to the text's magnitude (so longer text blocks may have greater magnitudes).

Returns:

  • (Float) —

    the current value of magnitude

end

#score ⇒ Float (readonly)

The overall emotional leaning of the text in the [-1.0, 1.0] range. Larger numbers represent more positive sentiments.
