Question

我在使用Jena RDF API的Java项目中使用Stanford POS tagger 3.7.0。 Jena需要slf4j-api-1.7.12.jar和slf4j-log4j12-1.7.12.jar，但是当尝试在类路径中调用具有这些jar的POS标记时，我收到以下错误：

我已经看到有similar problem的人通过从类路径中删除SLF4J来解决它。事实上，当我移除罐子时，POS标签工作正常，但Jena停止工作。

有没有办法让SLF4J保持在类路径中并且仍能让POS标记器工作？

我认为最好的解决方案是使用完整的Stanford CoreNLP 3.7.0版本，该版本不会遇到此问题，但会拥有所有的POS标记功能。

完整下载可在此处获取：

这个问题应该在Stanford CoreNLP 3.8.0的独立发行版中解决，我们将在初夏尝试发布。

Stanford POS标记符在类路径中不适用于SLF4J
