UIMA管道与斯坦福NER

Question

我在UIMA中整合了Stanford NER并开发了一条管道。 管道包含一个FileSystemCollectionReader，一个NERAnnotator和一个CasConsumer，但输出是不合适的。在我的输入目录中，我有两个文件，在运行管道后，我得到两个文件作为输出，但第二个文件与第二个输出中的第一个文件合并。我不知道这里发生了什么。

CasConsumer的代码：

    public final static String PARAM_OUTPUT="outputDir";

     @ConfigurationParameter(name = PARAM_OUTPUT)
     private String outputDirectory;

     public final static String PARAM_ANNOTATION_TYPES = "annotationTypes";


    enter code here
     @ConfigurationParameter(name = PARAM_ANNOTATION_TYPES,defaultValue="String")
     public List<String> annotationTypes;

     public void initialize(final UimaContext context) throws ResourceInitializationException 
     {
         super.initialize(context);
     }

     @Override
     public void process(JCas jcas)
     {

            String original = jcas.getDocumentText();

            try
            {
                String onlyText="";
                JCas sofaText = jcas.getView(NERAnnotator.SOFA_NAME);
                onlyText = sofaText.getDocumentText();
                String name = UUID.randomUUID().toString().substring(20);   
                    File outputDir = new File(this.outputDirectory+"/"+name);
                    System.out.print("Saving file to "+outputDir.getAbsolutePath());
                    FileOutputStream fos = new FileOutputStream(outputDir.getAbsoluteFile());
                    PrintWriter pw = new PrintWriter(fos);
                    pw.println(onlyText);
                    pw.close();

            }
            catch(CASException cae)
            {
                System.out.println(cae);
            }
            catch(FileNotFoundException fne)
            {
                System.out.print(fne);
            }               
    }
