我带着问题回来了。我正在使用 Rapid Miner 进行自动文本分类，但无法使其工作。我收到一条错误消息：“示例中未设置示例，违反了操作员性能”。知道那指的是什么吗？
I'm back with a question. I'm playing with Rapid Miner for automatic text classification and cant get it work. I'm getting an error that says, "no example set in the example, offending operator Performance ". Any idea what that is referring to ?

在 RapidMiner 中，您必须先使用转换器组件，然后才能将其用作示例集。因此，例如，如果您的输出为“doc”，则必须使用“文档到数据”组件才能将其链接到下一个输入“exa”。就这样！
In RapidMiner you have to use the converter components before using it as example sets. So, if you have an output as 'doc', for example, you have to use the component 'Documents to Data' in order to link it to the next input 'exa'. That´s all!

如果它说没有示例集，那么问题可能出在您的原始数据上。你能发布你的过程的图片吗？
例如，确保您已将初始输入连接到操作员 - 错误发生在哪两个操作员处？
一种想法：文本挖掘中设置的示例通常是你的文档集合，但是如果你真的使用文档（PDF、Word）那么你的格式将是文档（Doc），并且你可能需要将你的文档转换为数据（Documents to数据操作员）。然后您应该有一个示例集，您可以将其输入到 Performance 运算符中。
希望这会有所帮助 - 正如之前的评论所说，在不了解过程的情况下，很难准确说出错误在哪里。
If it says that there is no Example Set, then the issue is probably with your original data. Can you post an image of your process?
For instance, make sure that you have connected the initial input to your operator - what two operators does the error occur at?
One thought: the example set in text mining is usually your document collection, but if you are really using documents (PDF, Word) then your format will be Documents (Doc), and you may need to transform your documents to data (Documents to Data operator). Then you should have an Example Set that you can feed into your Performance operator.
Hope this helps - as the earlier comment said, without knowing the process, it is hard to tell exactly where the error is.
