Özet:

This thesis focuses on the role of modifiers used with discourse connectives and investigates modifiers in terms of affecting the modality of the discourse relations. Modifiers are originally adverbs used for different semantic purposes. The already annotated data in Turkish Discourse Bank, or TDB are used for identifying modifiers and classifying them. In the light of previous studies, the discourse connectives occuring with modifiers are analyzed and classified. The semantic distribution of modifiers is determined and their effect on the modality of discourse relations are examined. The data are put into a decision-tree algorithm and 10-fold cross-validation was applied. The results confirm that modifiers of discourse connectives have a role in discourse relations in terms of the modality of the relation.
