在heidelTime属性文件中设置路径以使用斯坦福德语词性标记器？

Question

我正在尝试检测德语文本中的时间信息。我尝试使用斯坦福的CoreNLP管道，因为在后期阶段(在时态标记之后)利用依赖关系解析信息将非常有帮助，但据我所知，无法将CoreNLP的集成时态标记器设置为德语。我说的对吗?事实上，有没有办法做到这一点。

现在，我正在尝试使用HeidelTime来分别检索tamporal标签。我想使用斯坦福大学的POS标记器。在Heideltime config.props文件中，我这样设置斯坦福POS标记器的路径(使用windows)：

model_path = C:\\Users\\milu\\Documents\\stanford-postagger-full-2017-06-09\\stanford-postagger-full-2017-06-09\\models
# leave this unset if you do not need one (e.g., /home/jannik/stanford-postagger-full-2014-01-04/tagger.config)
config_path =   

这是我在NetBeans上运行的代码，后面跟着我得到的错误。我指定POS标记器的路径的方式有问题吗？

public class RunHeideltimeInJava {


public static void main(String[] args) throws
        DocumentCreationTimeMissingException, ParseException {

    OutputType outtype = OutputType.XMI;
    POSTagger postagger = POSTagger.STANFORDPOSTAGGER;
    String conffile = "C:\\Users\\milu\\Documents\\NetBeansProjects\\TimeTagging\\src\\config.props";

    HeidelTimeStandalone hsNarratives = new HeidelTimeStandalone(Language.GERMAN,
            DocumentType.NARRATIVES, outtype, conffile, postagger);

    String narrativeText = "Ich habe letztes Wochenende neue Schuhe gekauft.";

    String xmiNarrativeOutput = hsNarratives.process(narrativeText);
    System.err.println("NARRATIVE*****" + xmiNarrativeOutput);
    String dctString = "2016-04-29";
    DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
    Date dct = df.parse(dctString);
 }
}

输出：

Answer 1

根据Heideltime手册，您只需将语言选项设置为德语：java -jar de.unihd.dbs.heideltime.standalone.jar -l GERMAN。然后，Heideltime会将此选项设置为所选的位置标签器(TreeTagger或StanfordPosTagger)。

关于TaggerConfig错误，当我用StanfordPosTagger在命令行上调用Heidletime时，甚至对于英文文本：java -jar de.unihd.dbs.heideltime.standalone.jar reference.txt -pos STANFORDPOSTAGGER，我也收到了相同的消息。

我按照说明编辑了heideltime配置文件并将Stanford POS标记器.jar文件添加到CLASSPATH: CLASSPATH

当我使用TreeTagger进行词性标记时，一切都运行得很好。
