使用cTAKES解析临床文件

Question

我试图弄清楚如何从Java运行临床文档管道.我有一套临床文件作为纯文本.我想解析这些文档并提取文档doc_ID中的列表,有频率为freq的CUI.我花了几天时间安装cTAKES并寻找解决方案.我将其缩小到ClinicalPipelineWithUmls.java,在那里进行测试并使用AnaylisisEngineDescription运行SimplePipeline.这是代码的一部分:

String documentText = "Text of document to test goes here, such as the following. No edema, some soreness, denies pain.";
InputStream inStream = InputStreamCollectionReader.convertToByteArrayInputStream(documentText);
CollectionReader collectionReader = InputStreamCollectionReader.getCollectionReader(inStream);
AnalysisEngineDescription pipelineIncludingUmlsDictionaries = AnalysisEngineFactory.createAnalysisEngineDescription(
            "desc/analysis_engine/AggregatePlaintextUMLSProcessor");
AnalysisEngineDescription xWriter = AnalysisEngineFactory.createPrimitiveDescription(
            XWriter.class,
            XWriter.PARAM_OUTPUT_DIRECTORY_NAME,
            AssertionConst.evalOutputDir,
            XWriter.PARAM_XML_SCHEME_NAME,
            XWriter.XMI,
            XWriter.PARAM_FILE_NAMER_CLASS_NAME,
            CtakesFileNamer.class.getName());
SimplePipeline.runPipeline(collectionReader, pipelineIncludingUmlsDictionaries, xWriter);
System.out.println("Done at " + new Date());

问题是找不到"InputStreamCollectionReader".我搜索它但到目前为止没有成功!你能给我一个提示或显示一些指示吗？谢谢你的帮助!

您想使用有什么特别的原因吗InputStreamCollectionReader？否则，这里有关于如何使用 TextReader 的示例。
