This thesis presents a methodology for an overall assessment of the Turkish Discourse Bank (TDB), a linguistic resource where discourse relations overtly expressed by discourse connectives have been identified and annotated with the two arguments they relate. We provide a quantitative and qualitative assessment of the TDB in order to establish the reliability of this discourse resource for Turkish and suggest that our methodology can be utilized for reliability evaluations of other annotated corpora. Our quantitative evaluation consists of calculating in depth statistical measures using the Kappa statistic and extra evaluators originally used in evaluating information retrieval systems. A two-way methodology for calculating the agreement statistics is proposed: a Common Arguments approach and an Overall approach. Although the Overall approach is e ective on its own, we propose a comparison of these two approaches, which enables to pin point sources of disagreements more accurately. As part of our qualitative evaluation we present a novel effort to automatically identify discursive uses of phrasal expressions that have been annotated systematically alongside explicit discourse connectives in the TDB, given any Turkish text. Our cascaded model, achieves full recall, provides 99.95% accuracy, and can be utilized to effortlessly enlarge the coverage of the TDB.

An Assessment of Explicit Inter- and Intra-sentential Discourse Connectives in Turkish Discourse Bank Zeyrek Bozşahin, Deniz (null; 2018-05-07) The paper offers a quantitative and qualitative analysis of explicit inter- and intra-sentential discourse connectives in Turkish Discourse Bank, or TDB version 1.1, a multi-genre resource of written Turkish manually annotated at the discourse level following the goals and principles of Penn Discourse TreeBank. TDB 1.1 is a 40K-word corpus involving all major discourse relation types (explicit discourse relations at intra- and inter-sentential positions, implicit discourse relations, alternative lexicalizat...
The Discourse structure of Turkish Demirşahin, Işın; Zeyrek Bozşahin, Deniz; Department of Cognitive Sciences (2015) This thesis investigates the structure of immediate discourse in Turkish. The first and fore- most question is how discourse is built. Are there components of discourse that constitute a predicate-argument structure, or is discourse realized by underlying non-structural ties that are merely made explicit by these components? If there is structure in discourse, what is the nature of this structure, and what is its complexity? For this purpose, we analyze the relations annotated in the Turkish Discourse Bank,...
Automatic sense prediction of implicit discourse relations in Turkish Kurfalı, Murathan; Zeyrek Bozşahin, Deniz; Department of Cognitive Sciences (2016) In discourse parsing, the sense prediction of the Implicit discourse relations poses the most significant challenge. The thesis aims to develop a supervised system to predict the sense of implicit discourse relations in Turkish Discourse Bank (TDB). In order to accomplish that goal, the discourse level annotations obtained from TDB are used. TDB follows the PDTB-2’s sense hierarchy and for all experiments within the current study, only CLASS senses are considered. As the primary experiment, the classifiers ...
Identity representations in the narratives on the EU-Turkey relations Özbey, Ebru Ece; Hauge, Hanna-Lisa; Rumelili, Bahar; Eralp, Atila (2019-3-19) This study aims to situate contemporary debates on the EU-Turkey relations in a broader historical context. It argues that understanding from where current narratives come and identifying their constituents, and particularly the narrators’ mutual perceptions on each other, which have endured through decades or even centuries, contributes to a deeper understanding of the relationship in critical ways. The paper is based on the results of two historically oriented studies carried out within the framework of t...
Vision of Modernity in the Early Turkish Republic: An Overview Şeker, Nesim (2007-09-01) : This article presents the main debates and existing lines of investigation about the foundation of the actual Turkey and which have been the factors of its process of modernization, examining the meaning and the principles of the kemalist political movement and its influence in the conformation of the contemporary Turkish State. Elements such as the political Islamism, the Kurd nationalism and the projects of integration with Europe are analyzed. As result of the combination of these factors, Turkish poli...
