java.lang.Object

com.ibm.watson.developer_cloud.service.WatsonService

com.ibm.watson.developer_cloud.natural_language_classifier.v1.NaturalLanguageClassifier

public class NaturalLanguageClassifier
extends WatsonService

The IBM Watson Natural Language Classifier service applies deep learning techniques to make predictions about the best predefined classes for short sentences or phrases. The classes can trigger a corresponding action in an application, such as directing a request to a location or person, or answering a question. After training, the service returns information for texts that it hasn't seen before. The response includes the name of the top classes and confidence values.

Method Detail

classify

public Classification classify(String classifierId,
                               String text)

Returns classification information for a classifier on a phrase.

Parameters:

classifierId - The classifier id

text - The submitted phrase to classify

Returns:

the classification of a phrase with a given classifier

createClassifier

public Classifier createClassifier(String name,
                                   String language,
                                   File trainingData)

Sends data to create and train a classifier, and returns information about the new classifier. The status has the value of `Training` when the operation is successful, and might remain at this status for a while.

Parameters:

name - the classifier name

language - IETF primary language for the classifier. for example: 'en'

trainingData - The set of questions and their "keys" used to adapt a system to a domain (the ground truth)

Returns:

the classifier

Parameters:

classifierId - the classifier ID

See Also:

Classifier

getClassifier

public Classifier getClassifier(String classifierId)

Parameters:

classifierId - the classifier ID

Returns:

the classifier list
