A type system for combinatory categorial grammar

Erkan, Güneş
This thesis investigates the internal structure and the computational representation of the lexical entries in Combinatory Categorial Grammar (CCG). A restricted form of typed feature structures is proposed for representing CCG categories. This proposal is combined with a constraint-based modality system for basic categories of CCG. We present some linguistic evidence to explain why both a uni cation-based feature system and a constraint-based modality system are needed for a lexicalist framework. An implementation of our system is also presented.


An Experimental study on acquisition of prepositions in English as a third language
Çabuk, Sakine; Sağın Şimşek, Sultan Çiğdem; Gracanın Yüksek, Martına; Department of English Language Teaching (2016)
This study explores the role of cross-linguistic influence in third language acquisition process by examining English adpositions. Comprehension, processing and production of English prepositions (in, on, at, behind, over, to) were examined through off-line and on-line data collection tasks to find out which of the two known languages (L1 or L2) is the major source of cross-linguistic influence on the acquisition of English (L3) adpositions given the fact that adpositions are morphologically and syntactical...
Gradient characteristics of the unaccusative/unergative distinction in Turkish : an experimental investigation
Acartürk, Cengiz; Zeyrek Bozşahin, Deniz; Department of Cognitive Sciences (2005)
This thesis investigates the gradient behaviour of monadic intransitive verb classes in Turkish, under an aspectual classification of the unaccusative/unergative verb types, namely The Split Intransitivity Hierarchy. This Hierarchy claims that intransitive verb types are subject to gradient acceptability in certain syntactic constructions. The methods used in judgment elicitation studies in psychophysics, such as the magnitude estimation technique have recently been adapted to be used in capturing gradient ...
Testing the interface hypothesis: L2 acquisition of English subjects and articles by Turkish learners
Geydir, Ecem; Sağın Şimşek, Sultan Çiğdem; Department of English Language Teaching (2020)
This thesis aims to expand the testing grounds of the Interface Hypothesis (IH) by investigating the acquisition of English subjects operating with pure syntax and article uses of (in)definiteness and genericity in English governed with external and internal interfaces respectively by L1-Turkish learners. Fifty-eight sophomore students who have been studying in the Department of Foreign Language Education of a state university in central Turkey were asked to complete a Grammaticality Judgement, a Discourse ...
Frequency-driven late fusion-based word decomposition approach on the phrase-based statistical machine translation systems
Tatlıcıoğlu, Mehmet; Yazıcı, Adnan; Department of Computer Engineering (2013)
Machine translation is the process of translating texts from a natural language to another by computers based on linguistic motivations, statistical approaches, or the combination of them. In this study, the frequency-driven late fusion-based word decomposition approach is introduced to improve the translation quality of the phrase-based statistical machine translation system from Turkish to English. This late fusion-based approach is compared with the standalone statistical and rule-based word decompositio...
Processing of conditional constructions in Turkish l2 speakers of English
Evcen, Ebru; Özge, Duygu; Department of English Language Teaching (2019)
This thesis aims to examine whether Turkish L2 learners of English process conditional constructions in an incremental and/or predictive manner. An offline grammaticality judgment (GJT) task was devised to test L2 learners’ sensitivity to grammatical violations and an online self-paced reading (SPR) task was designed to find out whether processing patterns of L2 learners would match existing L2 processing accounts. We manipulated the Connector Type (unless, unless…not, if…not) and Context Type (congruent, i...
