Question

我一直在尝试使用POS模型进行POS标记，但在加载模型时，我得到以下异常，这对于maxent和perceptron模型都会发生：

我已经尝试加载tokenizaton模型（en-token.bin）并且它的加载和工作正常。以下是我用来加载模型的java片段：

InputStream is = new FileInputStream(MODEL_PATH);
POSModel model = new POSModel(is);

我从http://www.opennlp.org/models-1.5/下载了模型（en-pos-perceptron.bin，en-pos-maxent.bin）。

Answer 1

事实证明，上面提到的网站上托管的模型文件已损坏，我正在尝试使用相同模型文件的GATE（文本工程的通用架构），因此我复制它们并将它们放在构建路径上它奏效了。
