Basic Examples  (2)

Use the "Profanity" built-in classifier to return True if a text contains strong language and False otherwise:

Wolfram Language code: Classify["Profanity", Import["http://www.urbandictionary.com/random.php"]]

Classify multiple examples:

Wolfram Language code: Classify["Profanity", {"I love this movie", "I am so sad", "My phone broke again"}]

Obtain the probabilities for the possible classes:

Wolfram Language code: Classify["Profanity", "This is a normal sentence", "Probabilities"]

Obtain a ClassifierFunction for this classifier:

Wolfram Language code: c = Classify["Profanity"]

Apply the classifier to a list of texts:

Wolfram Language code: c[{"This is a regular sentense", "I am so sad", "My phone broke again"}]

Scope  (1)

Load the ClassifierFunction corresponding to the built-in classifier:

Wolfram Language code: c = Classify["Profanity"]

Obtain the possible classes:

Wolfram Language code: Information[c, "Classes"]

Options  (3)

ClassPriors  (1)

Use a custom ClassPriors to restrict the possible outputs:

Wolfram Language code: Classify["Profanity", "There is nothing good about the fellas in this movie", ClassPriors -> <|True -> 0.5, False -> 0.5|>]

IndeterminateThreshold  (1)

Use a custom IndeterminateThreshold:

Wolfram Language code: Classify["Profanity", "My car broke again", IndeterminateThreshold -> 0.99]

UtilityFunction  (1)

Obtain the utility function of the classifier:

Wolfram Language code: utility = Information[Classify["Profanity"], "UtilityFunction"]

Modify this utility function to penalize True being misclassified as False:

Wolfram Language code: utility[True, False] = -1.;

Classify a text using this new utility:

Wolfram Language code: Classify["Profanity", Import["http://www.urbandictionary.com/random.php"], UtilityFunction -> utility]
