我正在尝试将 HeidelTime 包含到我的 uimaFIT-Pipeline 中。

这是我的管道：

AggregateBuilder builder = new AggregateBuilder();

CollectionReaderDescription reader = createReaderDescription(TextReader.class,
        TextReader.PARAM_SOURCE_LOCATION, dateTimePath, TextReader.PARAM_LANGUAGE, "en",
        TextReader.PARAM_PATTERNS, "*.txt");

AnalysisEngineDescription treeTagger = createEngineDescription(TreeTaggerWrapper.class,
        TreeTaggerWrapper.PARAM_LANGUAGE, "english",
        TreeTaggerWrapper.PARAM_ANNOTATE_PARTOFSPEECH, true,
        TreeTaggerWrapper.PARAM_ANNOTATE_SENTENCES, true, 
        TreeTaggerWrapper.PARAM_ANNOTATE_TOKENS, true);
builder.add(treeTagger);

AnalysisEngineDescription heidelTime = createEngineDescription(HeidelTime.class);
builder.add(heidelTime);

AnalysisEngineDescription intervalTagger = createEngineDescription(IntervalTagger.class);
builder.add(intervalTagger);

AnalysisEngineDescription xmiWriter = createEngineDescription(XmiWriter.class,
        XmiWriter.PARAM_TARGET_LOCATION, outputPath, 
        XmiWriter.PARAM_OVERWRITE, true);
builder.add(xmiWriter);

SimplePipeline.runPipeline(reader, builder.createAggregateDescription());

但是执行时出现以下异常：

Language parameter was specified as NULL.

如何在管道中设置语言和所有其他参数？我还没有找到办法。当我使用 HeidelTime 的独立版本时，我可以在构造函数中指定参数并且它工作正常。

我通过从 GitHub 下载 heideltime-master 并将以下文件夹放入我的 /src/main/resources 文件夹中解决了这个问题：

desc.annotator
desc.comsumer
desc.reader
desc.type

之后，我像这样创建了 AnalysisEngineDescriptions：

AnalysisEngineDescription heidelTime = createEngineDescriptionFromPath(
            "src/main/resources/desc/annotator/HeidelTime.xml");
            builder.add(heidelTime);

AnalysisEngineDescription intervalTagger = createEngineDescriptionFromPath(
            "src/main/resources/desc/annotator/IntervalTagger.xml");
            builder.add(intervalTagger);

有了这个，我终于让我的管道工作了，我可以在 Ruta Workbench 的 xmi 文件中看到 Timex3 注释。
