好的,我正在尝试使用 Mallet 对 Windows 中的一些文档进行分类

我已经在 Linux 中实现了它。只是无法在 Windows 中完成工作(目标环境)

我已将数据导入 .mallet 文件。

然后使用这个输入数据创建一个分类器。

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

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

但是,当我在 Linux 中运行时:

bin/mallet 分类目录 --input ./testfolder --output - --classifier nntp.classifier

它迭代测试文件夹中的任何文件并转储出它认为每个它的类。

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

它只是转储了命令列表:

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

我确实注意到的一件事:我

f 我bin/mallet classify-dir --help在 linux 中运行我得到帮助文件,即每个命令的描述,但是在 Windows 中相同的东西bin\mallet classify-dir --help不会产生相同的结果 - 只是上面的命令列表......(如果你输入 junk 作为命令,它会做同样的事情)

而较早的命令之一,例如bin/mallet import-dir --helpbin\mallet import-dir --help产生相同的完整帮助文件输出。

请注意,ignazio 提供的 .bat 文件的第 23 行有一个错字(不幸的是,它包含在 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 mallet.bat 文件有问题。你应该修改它:

@echo off

rem This batch file serves as a wrapper for several
rem  MALLET command line tools.

if not "%MALLET_HOME%" == "" goto gotMalletHome

echo MALLET requires an environment variable MALLET_HOME.
goto :eof

:gotMalletHome

set MALLET_CLASSPATH=%MALLET_HOME%\class;%MALLET_HOME%\lib\mallet-deps.jar
set MALLET_MEMORY=1G
set MALLET_ENCODING=UTF-8

set CMD=%1
shift

set CLASS=
if "%CMD%"=="import-dir" set CLASS=cc.mallet.classify.tui.Text2Vectors

if not "%CLASS%" == "" goto gotClass

goto :eof

:gotClass

set MALLET_ARGS=

:getArg

if "%1"=="" goto run
set MALLET_ARGS=%MALLET_ARGS% %1
shift
goto getArg

:run

java -Xmx%MALLET_MEMORY% -ea -Dfile.encoding=%MALLET_ENCODING% -classpath %MALLET_CLASSPATH% %CLASS% %MALLET_ARGS%

:eof

能够在 Windows 环境中进行分类。

我希望这会有所帮助。
