参数数量必须始终为偶数:opennlp [英] Number of parameters must be always be even : opennlp
问题描述
我一直在尝试使用命令行界面来训练我的模型,如下所示:
I've been trying to use the command Line interface to train my model like this:
opennlp TokenNameFinderTrainer -model en-ner-pincode.bin -iterations 500 \ -lang en -data en-ner-pincode.train -encoding UTF-8
控制台输出为:
Number of parameters must be always be even
Usage: opennlp TokenNameFinderTrainer[.evalita|.ad|.conll03|.bionlp2004|.conll02|.muc6|.ontonotes|.brat] [-factory factoryName] [-resources resourcesDir] [-type modelType] [-featuregen featuregenFile] [-nameTypes types] [-sequenceCodec codec] [-params paramsFile] -lang language -model modelFile -data sampleData [-encoding charsetName]
如果我不包括迭代次数,它可以正常工作。
有谁知道这背后的原因?
It works fine if I don't include the number of Iterations. Does anybody know the reason behind this?
谢谢!
推荐答案
实际上问题是
-params paramsFile
training parameters file.
-iterations num
number of training iterations, ignored if -params is used.
-cutoff num
minimal number of times a feature must be seen, ignored if -params is used.
如果有人使用 params
那么<$ c忽略$ c> iterations 和 cutoff
。因此,对于您的情况,会显示此信息消息。
If anyone use params
then iterations
and cutoff
are ignored. So for your case this info message is shown.

更新:
所以,请使用 ChunkerTrainerME
而不是 TokenNameFinderTrainer
您的命令应如下所示
opennlp ChunkerTrainerME -model en-ner-pincode.bin -iterations 500 \ -lang en -data en-ner-pincode.train -encoding UTF-8
UPDATE2:转换数据
我将使用西班牙语数据作为参考,但它与荷兰语的操作相同。您必须记住将-lang es更改为-lang nl并使用正确的培训文件。所以要将信息转换为OpenNLP格式:
UPDATE2: Converting the data
I will use Spanish data as reference, but it would be the same operations to Dutch. You just must remember change "-lang es" to "-lang nl" and use the correct training files. So to convert the information to the OpenNLP format:
$ opennlp TokenNameFinderConverter conll02 -data esp.train -lang es -types per > es_corpus_train_persons.txt
您也可以选择转换训练测试样本。
Optionally, you can convert the training test samples as well.
$ opennlp TokenNameFinderConverter conll02 -data esp.testa -lang es -types per > corpus_testa.txt
$ opennlp TokenNameFinderConverter conll02 -data esp.testb -lang es -types per > corpus_testb.txt
使用西班牙语数据进行培训
Training with Spanish data
为名称查找器训练模型:
To train the model for the name finder:
\bin\opennlp TokenNameFinderTrainer -lang es -encoding u
tf8 -iterations 500 -data es_corpus_train_persons.txt -model es_ner_person.bin
UPDATE3:转换数据(可选)
要将信息转换为OpenNLP格式:
UPDATE3: Converting the data (optional)
To convert the information to the OpenNLP format:
$ opennlp TokenNameFinderConverter conll03 -lang en -types per -data eng.train > corpus_train.txt
您也可以选择转换训练测试样本。
Optionally, you can convert the training test samples as well.
$ opennlp TokenNameFinderConverter conll03 -lang en -types per -data eng.testa > corpus_testa.txt
$ opennlp TokenNameFinderConverter conll03 -lang en -types per -data eng.testb > corpus_testb.txt
使用英语数据进行培训
您可以通过以下方式训练名称查找器的模型:
You can train the model for the name finder this way:
$ opennlp TokenNameFinderTrainer.conll03 -model en_ner_person.bin -iterations 500 \
-lang en -types per -data eng.train -encoding utf8
如果您已经转换了数据,然后您可以通过这种方式训练名称查找器的模型:
If you have converted the data, then you can train the model for the name finder this way:
$ opennlp TokenNameFinderTrainer -model en_ner_person.bin -iterations 500 \
-lang en -data corpus_train.txt -encoding utf8
