Automatic summarization can be further improved by preprocessing work, such as normalization of text, part-ofspeech tagging, morphological analysis, lemmatization and stemming (Leite et al., 2007;Torres-Moreno, 2012;Torres-Moreno, 2014;Nuzumlal andÖzgür, 2014;Eryigit et al., 2008).
we further apply the needed software tools and provide the annotated output corpus freely.
