Document Conversion のおかげで、PDF から変換された HTML ドキュメントで Concept Insights を使用するためのクラスを作成したいと考えています。Git ディレクトリを表示する Eclipse IDE を使用しています。実行すると、応答がありません。きれいに保ちたいのですが、各メソッドが必要な情報を確実に取得できるようにします。とにかく、ここまでのコードです。

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次に示します。コンセプト インサイトを使用してコンセプトを抽出します。

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());
    }
  }

}

資格情報が存在する場合は、そこから資格情報を読み込みますvcap.txt。
