    A Study of the Information Services On Turkish High Schools
    (Elsevier Science BV, 2011) Darvish, Hamid R.
    The World Wide Web went public in 1989. Since then, every organization has come to utilize web-based technologies for their various purposes. Educational institutions have implemented web technology in their contemporary curriculums. The aim of this study is to investigate five private schools in Ankara, Turkey and to unravel the impact of information technology (internet usage, information services) in their programs. The five high schools were: Ari College, TED Ankara College, Tevfik Fikret High School, METU (Middle East Technical University) College and Bilkent High School. We conducted a qualitative research on the selected high schools by observing and collecting data. Research was done from March-May 2009. We found out that internet services in high schools are not utilized to their full capacity. (C) 2011 Published by Elsevier Ltd.

    Diffusion of Latent Semantic Analysis As A Research Tool: A Social Network Analysis Approach
    (Elsevier, 2010) Tonta, Yaşar; Darvish, Hamid R.
    Latent semantic analysis (LSA) is a relatively new research tool with a wide range of applications in different fields ranging from discourse analysis to cognitive science, from information retrieval to machine learning and so on. In this paper, we chart the development and diffusion of LSA as a research tool using social network analysis (SNA) approach that reveals the social structure of a discipline in terms of collaboration among scientists. Using Thomson Reuters' Web of Science (WoS), we identified 65 papers with "latent semantic analysis" in their titles and 250 papers in their topics (but not in titles) between 1990 and 2008. We then analyzed those papers using bibliometric and SNA techniques such as co-authorship and cluster analysis. It appears that as the emphasis moves from the research tool (LSA) itself to its applications in different fields, citations to papers with LSA in their titles tend to decrease. The productivity of authors fits Lotka's Law while the network of authors is quite loose. Networks of journals cited in papers with LSA in their titles and topics are well connected.

    Citation Count: DARVISH, H.R., (2007). “Is Semantic Web Real or Hype?. Çankaya Üniversitesi Fen-Edebiyat Fakültesi, Journal of Arts and Sciences Sayı:8, pp.17-21
    “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
