Javaでドキュメント変換とコンセプト分析を使用するためのクラスを作成する

Question

ドキュメント変換により、HTMLドキュメントのConcept InsightsをPDFから変換するためのクラスを作成したいと考えています。私は私のGitディレクトリのビューでEclipse IDEを使用しています。私はそれを実行すると、私は応答がありません。私はそれをきちんと保ちたいが、それぞれのメソッドが必要な情報を取得することを確認する。とにかく、これまでのコードはここにあります。

package example.servlet;

ここでは、ドキュメント変換を使用してpdfをテキストに変換するクラスの例を示します。 Concept Insightsを使用して概念を抽出します。

package com.ibm.watson.developer_cloud.retrieve_and_rank.v1; 

import java.io.File; 
import java.io.FileInputStream; 

import org.apache.commons.io.IOUtils; 

import com.ibm.watson.developer_cloud.concept_insights.v2.ConceptInsights; 
import com.ibm.watson.developer_cloud.concept_insights.v2.model.Annotations; 
import com.ibm.watson.developer_cloud.concept_insights.v2.model.Graph; 
import com.ibm.watson.developer_cloud.concept_insights.v2.model.ScoredConcept; 
import com.ibm.watson.developer_cloud.document_conversion.v1.DocumentConversion; 
import com.ibm.watson.developer_cloud.util.CredentialUtils; 


public class WatsonExample { 
    public static void loadCredentialsFromFile() { 
    try { 
     CredentialUtils.setServices(IOUtils.toString(new FileInputStream("vcap.txt"))); 
    } catch (Exception e) { 
     System.out.println("Error reading vcap.txt file"); 
     e.printStackTrace(); 
    } 
    } 


    public static void main(String[] args) { 
    loadCredentialsFromFile(); 
    ConceptInsights conceptInsights = new ConceptInsights(); 
    DocumentConversion documentConversion = new DocumentConversion(DocumentConversion.VERSION_DATE_2015_12_01); 

    // extract the text from the pdf 
    String text = documentConversion.convertDocumentToText(new File("docs/cpc-scheme-A.pdf")); 

    // annotate the text 
    Annotations annotations = conceptInsights.annotateText(Graph.WIKIPEDIA, text); 

    // print out concepts 
    for (ScoredConcept concept : annotations.getAnnotations()) { 
     System.out.println(concept.toString()); 
    } 
    } 

} 

資格情報がある場合はvcap.txtから読み込まれます。
