This study primarily aims to build a Turkish psycholinguistic database including three variables: word frequency, age of acquisition (AoA), and imageability, where AoA and imageability information are limited to nouns. We used a corpus-based approach to obtain information about the AoA variable. We built two corpora: a child literature corpus (CLC) including 535 books written for 3-12 years old children, and a corpus of transcribed children’s speech (CSC) at ages 1;4-4;8. A comparison between the word frequencies of CLC and CSC gave positive correlation results, suggesting the usability of the CLC to extract AoA information. We assumed that frequent words of the CLC would correspond to early acquired words whereas frequent words of a corpus of adult language would correspond to late acquired words. To validate AoA results from our corpus-based approach, a rated AoA questionnaire was conducted on adults. Imageability values were collected via a different questionnaire conducted on adults. We conclude that it is possible to deduce AoA information for high frequency words with the corpus-based approach. The results about low frequency words were inconclusive, which is attributed to the fact that corpus-based AoA information is affected by the strong negative correlation between corpus frequency and rated AoA.

A conceptual evaluation of frequency diverse arrays and novel utilization of LFMCW Eker, Taylan; Demir, Şimşek; Department of Electrical and Electronics Engineering (2011) Phased array based systems have extending applications in electronic warfare, radio astronomy, civilian applications with technological advancements. The main virtue offered by these systems is the creation of agile beams with utilization of phase shifting or delay elements. In fact, the desire for flexible steering comes with a cost. Frequency Diverse Array (FDA) concept is another approach to beam steering problem. In this context, the subsequent antenna elements are fed with stepped discrete frequencies ...
An investigation for maturity level and roadmap of unmanned aerial vehicle technologies in Turkey Türk, Afşar; Çakır, Serhat; Department of Science and Technology Policy Studies (2020-10) This research aims to investigate problems, needs of the UAV industry, and required actions for the future in Turkey, to determine technological maturity criteria, and to prepare a technology roadmap. Qualitative data collected through interviews with actors from institutions/enterprises operating in the UAV industry is analysed, and inferences about the Turkish UAV industry are made, and suggestions for findings are developed. Twenty statements prepared to determine the technology goals for the Turki...
A new hybrid multi-relational data mining technique Toprak, Seda Dağlar; Toroslu, İ. Hakkı; Department of Computer Engineering (2005) Multi-relational learning has become popular due to the limitations of propositional problem definition in structured domains and the tendency of storing data in relational databases. As patterns involve multiple relations, the search space of possible hypotheses becomes intractably complex. Many relational knowledge discovery systems have been developed employing various search strategies, search heuristics and pattern language limitations in order to cope with the complexity of hypothesis space. In this w...
Adapting and testing psycholinguistic toolboxes for Turkish visual word recognition studies Erten, Begüm; Bozşahin, Hüseyin Cem; Zeyrek Bozşahin, Deniz; Department of Cognitive Sciences (2013) This study presents two different software programs to be used in Turkish visual word recognition studies: KelimetriK and Wuggy with a Turkish plug-in extension. KelimetriK is a query-based software program developed as part of this thesis. KelimetriK provides word and bi-gram/tri-gram frequencies, orthographic neighborhood (ON), orthographic relatedness (transposed letter similarity and subset/superset similarity) and OLD20 (orthographic Levensthein Distance 20) scores. Wuggy is a pseudoword (i.e. wordlike...
