public class WekaTextDirectoryReader extends adams.flow.transformer.AbstractTransformer
Loads all text files in a directory and uses the subdirectory names as class labels. The content of the text files will be stored in a String attribute, the filename can be stored as well.
Uses the WEKA weka.core.converters.TextDirectoryLoader converter.
Input/output:
- accepts:
java.lang.String
java.io.File
- generates:
weka.core.Instances
Valid options are:
-D <int> (property: debugLevel) The greater the number the more additional info the scheme may output to the console (0 = off). default: 0 minimum: 0
-name <java.lang.String> (property: name) The name of the actor. default: WekaTextDirectoryReader
-annotation <adams.core.base.BaseText> (property: annotations) The annotations to attach to this actor. default:
-skip (property: skip) If set to true, transformation is skipped and the input token is just forwarded as it is.
-stop-flow-on-error (property: stopFlowOnError) If set to true, the flow gets stopped in case this actor encounters an error; useful for critical actors.
-store-filename (property: storeFilename) If enabled, the filename will be stored in extra attribute.
-char-set <java.lang.String> (property: charSet) The character set to use when loading the text files. default: UTF-8
