Stanford中NER模型的非缺省位置
Stanford中NER模型的非缺省位置
提问于 2015-02-06 20:05:37
默认情况下，Stanford按以下顺序使用这三种NER模型：
从edu/stanford/nlp/models/ner/english.all.3class.distsim.crf.ser.gz加载分类器。完成20.6秒。从edu/stanford/nlp/models/ner/english.conll.4class.distsim.crf.ser.gz加载分类器。完成[16.4秒从edu/stanford/nlp/models/ner/english.muc.7class.distsim.crf.ser.gz加载分类器.完成18.2秒。
但是，如果我们想从我的计算机中的某个位置加载我们自己的模型，那么我们必须设置哪个属性？
因为，如果我提取Stanford-corenlp-3.2.0Models.jar的内容并将我的模型添加到其中，重新创建jar文件并重新编译corenlp。但是，在加载新添加的分类器时，我得到以下错误：

-ner.model选项将尝试在Java上或作为文件系统路径查找该文件。如果您给出了文件系统上的ser.gz文件的绝对路径，那么它应该会很好地加载。

我认为FileNotFoundException是假的/误导的，这里的问题是ClassCastException从ArrayList到FeatureFactory的第一个错误。我认为这显示了您的类路径，并且正在运行一个旧版本的CRFClassifier，从我们对CRFClassifier进行修改以支持拥有FeaturyFactory的列表开始。我会仔细检查类路径上的内容。

通过提取重新编译的models.jar是否在预期路径(edu/stanford/nlp/ model /ner/)中具有支持文件的自定义模型。
