HeidelTime:语言参数指定为NULL

Question

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

以下是我的工作流程：

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());

但是当我执行它时，我得到了以下异常：

Language parameter was specified as NULL.

如何在流水线中设置语言和所有其他参数？我还没有找到一种方法。当我使用HeidelTime的独立版本时，我可以在构造函数中指定参数，它工作得很好。

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

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

之后，我创建了AnalysisEngineDescriptions，如下所示：

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);

这样，我的管道终于可以工作了，我可以在Ruta工作台中看到我的xmi文件中的Timex3注释。
