我正在尝试从 UIMA fit 管道执行一个简单的示例 Ruta 脚本。

STRING s;
BOOLEAN a;
STRING s2 = "LAuGH";
DECLARE Test;
BLOCK(forEACH) W{}{
    W{->MATCHEDTEXT(s), ASSIGN(a,equals(s,s2))};
    W{->MATCHEDTEXT(s), ASSIGN(a,equalsIgnoreCase(s,s2))};
    W{a ->Test};
}

该脚本在作为具有单独 RUTA 项目的独立脚本执行并创建测试注释时工作正常。但是，在具有 UIMA fit 管道的 java 项目中，我收到以下错误：

该脚本无法解析，这很奇怪。我正在使用来自 maven repo (2.4.0) 的最新版本的 ruta-core。有谁知道为什么会这样？谢谢。

当使用 uimaFIT 手动创建分析引擎时，不使用预配置的描述符，而只使用实现 RutaEngine.class，则需要自己配置参数additionalExtension。此参数列出语言扩展工厂。

更改您的 java 行

 ... = AnalysisEngineFactory.createEngine(RutaEngine.class);

至

 ... = AnalysisEngineFactory.createEngine(RutaEngine.class, RutaEngine.PARAM_ADDITIONAL_EXTENSIONS, new String[]{BooleanOperationsExtension.class.getName(), StringOperationsExtension.class.getName()});

应该做的伎俩。
