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

IBM Watson™ Natural Language Classifier uses machine learning algorithms to return the top matching predefined classes for short text input. You create and train a classifier to connect predefined classes to example texts so that the service can apply those classes to new inputs.

Constructor Detail

NaturalLanguageClassifier

public NaturalLanguageClassifier()

Instantiates a new `NaturalLanguageClassifier`.

NaturalLanguageClassifier

public NaturalLanguageClassifier(java.lang.String username,
                         java.lang.String password)

Instantiates a new `NaturalLanguageClassifier` with username and password.

Parameters:

username - the username

password - the password

NaturalLanguageClassifier

public NaturalLanguageClassifier(IamOptions iamOptions)

Instantiates a new `NaturalLanguageClassifier` with IAM. Note that if the access token is specified in the iamOptions, you accept responsibility for managing the access token yourself. You must set a new access token before this one expires. Failing to do so will result in authentication errors after this token expires.

Parameters:

iamOptions - the options for authenticating through IAM

Method Detail

classify

public ServiceCall<Classification> classify(ClassifyOptions classifyOptions)

Classify a phrase. Returns label information for the input. The status must be `Available` before you can use the classifier to classify text.

Parameters:

classifyOptions - the ClassifyOptions containing the options for the call

Returns:

a ServiceCall with a response type of Classification

classifyCollection

public ServiceCall<ClassificationCollection> classifyCollection(ClassifyCollectionOptions classifyCollectionOptions)

Classify multiple phrases. Returns label information for multiple phrases. The status must be `Available` before you can use the classifier to classify text. Note that classifying Japanese texts is a beta feature.

Parameters:

classifyCollectionOptions - the ClassifyCollectionOptions containing the options for the call

Returns:

a ServiceCall with a response type of ClassificationCollection

createClassifier

public ServiceCall<Classifier> createClassifier(CreateClassifierOptions createClassifierOptions)

Create classifier. Sends data to create and train a classifier and returns information about the new classifier.

Parameters:

createClassifierOptions - the CreateClassifierOptions containing the options for the call

Returns:

a ServiceCall with a response type of Classifier

deleteClassifier

public ServiceCall<java.lang.Void> deleteClassifier(DeleteClassifierOptions deleteClassifierOptions)

Delete classifier.

Parameters:

deleteClassifierOptions - the DeleteClassifierOptions containing the options for the call

Returns:

a ServiceCall with a response type of Void

getClassifier

public ServiceCall<Classifier> getClassifier(GetClassifierOptions getClassifierOptions)

Get information about a classifier. Returns status and other information about a classifier.

Parameters:

getClassifierOptions - the GetClassifierOptions containing the options for the call

Returns:

a ServiceCall with a response type of Classifier

listClassifiers

public ServiceCall<ClassifierList> listClassifiers(ListClassifiersOptions listClassifiersOptions)

List classifiers. Returns an empty array if no classifiers are available.

Parameters:

listClassifiersOptions - the ListClassifiersOptions containing the options for the call

Returns:

a ServiceCall with a response type of ClassifierList

listClassifiers

public ServiceCall<ClassifierList> listClassifiers()

List classifiers. Returns an empty array if no classifiers are available.

Returns:

a ServiceCall with a response type of ClassifierList

classify

public ServiceCall<Classification> classify(java.lang.String classifierId,
                                   java.lang.String text)

Classify. This method is here for backwards-compatibility with the other version of classify.

Parameters:

classifierId - the classifier ID

text - the submitted phrase to classify

Returns:

the classification of a phrase with a given classifier

createClassifier

public ServiceCall<Classifier> createClassifier(java.lang.String name,
                                       java.lang.String language,
                                       java.io.File trainingData)
                                         throws java.io.FileNotFoundException

Create classifier. This method is here for backwards-compatibility with the old version of createClassifier.

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:

Parameters:

classifierId - the classifier ID

Returns:

the classifier

getClassifiers

public ServiceCall<ClassifierList> getClassifiers()
