分類器作成

Java

package com.nlc.sample1;

import java.io.File;

import com.ibm.watson.developer_cloud.natural_language_classifier.v1.NaturalLanguageClassifier;
import com.ibm.watson.developer_cloud.natural_language_classifier.v1.model.Classifier;

/**
 * Hello world!

 */
public class App 
{
	
	final private static String UserName = "資格情報のユーザー名";
	final private static String Password = "資格情報のパスワード";
	
    public static void main( String[] args )
    {
        System.out.println( "Natural Language Classifier createClassifier start" );
        
        // インスタンス生成
        NaturalLanguageClassifier service = new NaturalLanguageClassifier();
        service.setUsernameAndPassword(UserName, Password);
        
        // 分類キー作成
        Classifier classifier = service.createClassifier("My Classifier", "ja", 
        		new File("./nlc/training02.csv")).execute();
        
        // 結果表示
        System.out.println(classifier);
        
        System.out.println( "Natural Language Classifier createClassifier end" );
    }
}

Natural Language Classifier createClassifier start

  "classifier_id": "分類器のID",
  "language": "ja",
  "name": "My Classifier",
  "status": "Training",

        NaturalLanguageClassifier service = new NaturalLanguageClassifier();
        service.setUsernameAndPassword(UserName, Password);
        
        // 分類キーより取得
        Classifier classifier = service.getClassifier("分類器のID").execute();
        
        // 結果表示
        System.out.println(classifier);
        
        System.out.println( "Natural Language Classifier getClassifier end" );
    }

とりあえずこんな感じ
watsonで使えるかわからないけどちょっとずつ調べていく
