Article Author identification for Turkish texts(Çankaya Üniversitesi, 2007) Görür, Abdül Kadir; Görür, Abdül Kadir; Bilgisayar MühendisliğiThe main concern of author identification is to define an appropriate characterization of documents that captures the writing style of authors. The most important approaches to computer-based author identification are exclusively based on lexical measures. In this paper we presented a fully automated approach to the identification of the authorship of unrestricted text by adapting a set of style markers to the analysis of the text. In this study, 35 style markers were applied to each author. By using our method, the author of a text can be identified by using the style markers that characterize a group of authors. The author group consists of 20 different writers. Author features including style markers were derived together with different machine learning algorithms. By using our method we have obtained a success rate of 80% in avaregeArticle Calculation of signal sources coordinates in 2D and 3D space(Çankaya Üniversitesi, 2008) Alyeksyeyenkov, Yuriy; Bilgisayar MühendisliğiMethods of calculations of coordinate of signal sources which are inaccessible and direct measurement of their properties is impossible are analyzed. Cases of 2D – 3D spaces and single – multiple sources of signal are investigated separately. Recommendations and necessary mathematical equations for practical applications are given. Advantage of sources coordinate measurement using signal parameters in frequency domain is shown. Experimental analysis of methods on the base of MATLAB modeling demonstrates full coincidence of theory and practiceArticle Compensation of errors in multi-channel analog-to-digital convertors at signal processing of multidimensional arrays(Çankaya Üniversitesi, 2012) Alyeksyeyenkov, Yuriy; Bilgisayar MühendisliğiÇıktı sinyalinin çok boyutlu dizin veya bir çok tek boyutlu dizinler ¸seklinde olduğu, çok kanallı analog sayısal çevirgeç (ADC)’lerde hataların kaynakları ve telafi yöntemleri dikkate alınmıştır. Analog sayısal çevirgeçlerde yaygın olan bir çok kanal için örnekle ve tut devresinde hata kaynağı analiz edilmiştir. Sinyal kaynağı’nın geometrik koordinatları algoritması zaman ve frekans bölgesinde hataların telafi yöntemleri analiz edilmiştir.Article “Is semantic web real or hype?(Çankaya Üniversitesi, 2007) Darvish, Hamid R.In this paper, first, I describe semantic web and second, I elaborate on four blocks of semantic web (XML, Resource Description Framework (RDF), RDF Schema, and Ontology) and finally some example of current semantic web tools and application. Semantic web is an extension of HTML (Hyper Text Mark up Language) and XML (Extensible Markup Language). XML and HTML play big part on semantic web implementation. The semantic web has been supported by W3C (www.w3c.org) organization, an international organization body for World Wide Web standardization
