public class LeipzigDoccatSampleStream
extends FilterObjectStream<String,DocumentSample>

Stream filter to produce document samples out of a Leipzig sentences.txt file. In the Leipzig corpus the encoding of the various sentences.txt file is defined by the language. The language must be specified to produce the category tags and is used to determine the correct input encoding.

The input text is tokenized with the SimpleTokenizer. The input text classified by the language model must also be tokenized by the SimpleTokenizer to produce exactly the same tokenization during testing and training.
