Question

我想在GATE中使用TermRaider功能。有人可以发布一些示例代码来加载并在java类中使用此资源。我试过跟随但失败了。

 Gate.getCreoleRegister().registerDirectories(new URL("file:///D:/misc_workspace/gate-7.1-build4485-SRC/plugins/TermRaider"));

    ProcessingResource termRaider = (ProcessingResource) Factory.
    createResource("gate.termraider.TermRaiderEnglish",Factory.newFeatureMap());

Exception:
gate.termraider.TermRaiderEnglish cannot be cast to gate.ProcessingResource

有人可以建议我该怎么做。

Answer 1

TermRaider系统不是单个PR，它是一个完整的应用程序（事实上是一个Groovy ScriptableController）。 TermraiderEnglish资源只是一个钩子，可以使该应用程序出现在GATE Developer GUI的“现成应用程序”菜单中。

在嵌入式代码中，您可以使用PersistenceManager

加载应用程序

File termRaiderPlugin = new File(Gate.getPluginsHome(), "TermRaider");
File gappFile = new File(new File(termRaiderPlugin, "applications"),
            "termraider-eng.gapp");
CorpusController trApp = (CorpusController)PersistenceManager.loadObjectFromFile(
    gappFile);

当您在语料库上运行应用程序时，它会创建三个“termbank”LR的新实例，其中包含有关新发现的术语的信息。 vanilla应用程序实际上是用于GUI而不是嵌入式使用，因此它不会在任何有用的地方存储对这些新LR的引用 - 您必须询问CreoleRegister才能找到它们。您可能更喜欢制作自己的应用程序副本并调整控制脚本以将术语库实例存储为Corpus上的（例如）功能，方法是添加类似

的内容

corpus.features.tfidfTermbank = termbank0
corpus.features.annotationTermbank = termbank1
corpus.features.hyponymyTermbank = termbank2

到控制脚本的末尾。然后，您可以通过corpus.getFeatures().get("tfidfTermbank")等

在Java代码中访问它们

由于这些Termbank类本身是TermRaider插件的一部分，因此您可能希望将gate-termraider.jar添加到主应用程序类路径中，而不是通过GateClassLoader加载它。
