Part-of-speech tagset and stemming

The Turkish Web corpora are part-of-speech tagged with the following Turkish TRMorph Penn Treebank tagset summary indicating the part of speech and grammatical category. The corpus texts also contain stemming when each word form from the corpus is assigned to its word stem. In this case, stems replace lemma attributes.

Genre annotation and topic classification
