Java'da Belge Dönüştürme ve Kavram Trendlerini kullanma için sınıf oluşturma

Question

Bu nedenle, Document Conversion sayesinde PDF'den dönüştürülen HTML belgelerinde Concept Insights'ı kullanmak için sınıflar oluşturmak istiyorum. Git dizininin görünümünde bir Eclipse IDE kullanıyorum. Koştuğumda cevap alamıyorum. Onu düzenli tutmak istiyorum ancak her yöntemin ihtiyaç duyduğu bilgileri aldığından emin olun. Neyse, işte kod şu ana kadar.

package example.servlet;

Belge Dönüştürme özelliğini kullanarak pdf'yi metne dönüştürecek bir örnek sınıfı; Concept Insights kullanarak kavramları ayıklayın. Varsa

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()); 
    } 
    } 

} 

O vcap.txt gelen kimlik bilgilerini yükleyecektir.
