Question

好的我正在尝试使用Mallet对Windows中的某些文档进行分类

我在Linux中实现了它。只是无法让它在Windows（目标环境）中完成工作

我已将数据导入.mallet文件。

然后使用此输入数据创建分类器。

-rw-r--r-- 1 henry henry 15197116 Feb 23 15:56 nntp.classifier

和

07/03/2014  21:28        15,197,116 nntp.classifier

然而，当我在Linux中运行时：

bin / mallet classify-dir --input ./testfolder --output - --classifier nntp.classifier

它会迭代testfolder中的所有文件并转出它认为的每个类。

但是如果我在Windows中运行相同的命令：

bin\mallet classify-dir --input ./testfolder --output - --classifier nntp.classifier

它只是转出命令列表：

Mallet 2.0 commands:
  import-dir        load the contents of a directory into mallet instances (one per file)
  import-file       load a single file into mallet instances (one per line)
  import-svmlight   load a single SVMLight format data file into mallet instances (one per line)
  train-classifier  train a classifier from Mallet data files
  train-topics      train a topic model from Mallet data files
  infer-topics      use a trained topic model to infer topics for new documents
  estimate-topics   estimate the probability of new documents given a trained model
  hlda              train a topic model using Hierarchical LDA
  prune             remove features based on frequency or information gain
  split             divide data into testing, training, and validation portions
Include --help with any option for more information

我注意到的事情：我

f我在linux中运行bin/mallet classify-dir --help我得到了帮助文件，即每个命令的描述，但Windows bin\mallet classify-dir --help中的相同内容不会产生相同的结果 - 只是上面的命令列表... （如果你输入垃圾作为命令它会做同样的事情）

而早先的命令之一，例如bin/mallet import-dir --help和bin\mallet import-dir --help生成相同的完整帮助文件输出。

Answer 1

请注意，ignazio提供的.bat文件的第23行有一个拼写错误（并且很遗憾地包含在mallet-2.0.7下载中）导致它查找“import-smvlight”而不是“import” -svmlight“，这是帮助信息中指定的内容。如果要使用此功能，请确保切换“m”和“v”。

bin目录中的whit mallet.bat文件存在问题。你应该在：

修改它

能够在Windows环境中进行分类。

我希望这可以提供帮助。

Mallet适用于Linux但不适用于Windows
